NG series safety switches with solenoid and RFID technology

Description

These switches are used on machines where the hazardous conditions remain for a while, even after the machines have been switched off, for example because of mechanical inertia of pulleys, saw disks, parts under pressure or with high temperatures. Thus, the switches can also be used if individual guards are only to be opened under certain conditions.

Versions with mode 1 (safety outputs active when guard closed and locked) are interlocks with guard locking acc. to ISO 14119; the product is labelled with the symbol shown.

Maximum safety with a single device

The NG series switches are con-

structed with redundant electronics. As a result, the maximum PL e and SIL 3 safety levels can still be achieved through the use of a single device on a guard. This avoids expensive wiring in the ﬁeld and allows faster installation. Inside the control cabinet, the two electronic safety outputs must be connected to a safety module with OSSD inputs or to a safety PLC.

Series connection of several switches

One of the most important features of the NG series is the possibility of connecting up to 32 sensors in series, while still maintaining the maximum safety levels PL e laid down in EN 13849-1 and SIL 3 acc. to EN 62061.

missible in safety systems which have a safety module at the end of the chain that monitors the outputs of the last NG switch.

The fact that the PL e safety level can be maintained even with 32 sensors connected in series demonstrates the extremely secure structure of each single device.

This connection type is per-

RFID actuators with high coding level

The NG series is provided with an electronic system based on RFID technology to detect the actuator. This allows to provide each actuator with different coding and makes it impossible to tamper with a device by using another actuator of the same series. Millions

of different coding combinations are possible for the actuators. They are therefore classiﬁed as high level coded actuators, according to EN ISO 14119.

Dustproof

The switch is provided with a through hole for inserting the actuator. Thanks to this unique feature, any dust that enters the actuator hole can always come out on the opposite side instead of remaining inside. Moreover, the lock pin is provided with a diaphragm seal, making the system suitable for critical environments with a high level of dust.

Holding force of the locked actuator

tees a maximum actuator holding force of F

= 9750 N. This is one of the highest

1max

values currently available on the market today, making this device suitable for heavyduty applications.

Integrated control devices

The switch is also available with elevated cover. Control devices such as buttons, emergency buttons, indicator lights or selectors can thereby be attached directly to the switch together with corresponding contact blocks.

The result is a compact solution with direct access to control devices without needing to install them separately on the switch panel or in their own housing. The devices can be illuminated and, thanks to the PUSH-IN spring-operated connections, wiring is quick and intuitive.

The switch is provided with a wide centring inlet for the actuator pin. This solution makes it easier to align the actuator and the opening hole on the head during installation. Moreover, this solution drastically reduces the probability of a collision between the switch and the actuator, making it possible to install the device even on inaccurately closing doors.

Push-in spring-operated connections

The switch is provided with a PUSH-IN type spring-operated connection system on the inside. This technology allows wiring to be performed quickly and easily, as the wire just needs to be inserted into the appropriate hole in order to establish the electrical connection and automatically secure the wire. This operation can be performed with rigid or ﬂexible wires with a crimped wire-end sleeve and requires no tools. Release is obtained by pressing the appropriate wire-releasing button.

General Catalogue Safety 2017-2018

Six LEDs for immediate diagnosis

As the LEDs have been designed for quick immediate diagnosis, the status of each input and output is highlighted by one speciﬁc LED. This makes it possible to quickly identify the interruption points in the safety chain, which device is released, which door is opened and any errors inside the device. All of this at a glance, without needing to decode complex ﬂashing sequences.

Holding force of the unlocked actuator

The inside of each switch features a device which holds the actuator in its closed position. Ideal for all those applications where several doors are unlocked simultaneously, but only one is actually opened. The device keeps all the unlocked doors in their position with a retaining force of 30 N~, stopping any vibrations or gusts of wind from opening them.

Function for protecting against recoil forces

If a door is closed too quickly or with so much force that the recoil would cause it to open again, a special function in the NG switch prevents locking. This function prevents the immediate locking of the door if the lock signal is applied. This protects the switch against recoil forces that occur during instantaneous locking. This serves to protect the switch from damage and forces the operator to close the door more gently.

Protection against tampering

Each actuator of the NG series is supplied with four protective caps. Not only do the caps prevent dirt from accumulating and simplify cleaning, they also block access to the fastening screws of the actuator. As a result, standard screws can be used instead of tamper-proof screws.

Articulated actuator for inaccurately closing doors

All NG series actuators are articulated, thereby allowing the actuator pin to be safely guided into the switch through the centring hole. As a result, the actuator and switch do not need to be precisely aligned during installation. In addition, the device can thereby be used on doors with a minimum actuation

needing to be angled.

radius of 150 mm without the actuation pin

Head and devices with variable orientation

The system can be variably conﬁgured by loosening the 4 screws on the head.

The key release device and the emergency release button can also be rotated and secured independently of one another in steps of 90°. The device can thus assume 16 different conﬁgurations.

Key release device and emergency release button

The key release device (auxiliary release) is used to permit unlocking of the actuator only by personnel in possession of the key. The device also functions with no power supply and, once actuated, prevents the guard from being locked.

The emergency release button (escape release) allows actuator release and

immediate opening of the door. Generally used in machines within which an operator could inadvertently become trapped, it faces towards the machine interior, to allow the operator to exit even in the event of a power failure. The button has two stable states and can be freely extended in length with suitable extensions (see accessories).

Both devices can be positioned on the four sides of the switch. As a result, it can be installed both towards the interior and towards the exterior of the machine.

Two safety output actuation modes

Two different activation modes are available for the switch: active safety outputs with guard closed and locked (mode

1) for machines with inertia or active safety outputs with guard closed (mode 2) for machines without inertia.

Non-detachable head and release devices

The head and the release device can be rotated but cannot be detached from each other. This makes the switch more secure since the problem of incorrect assembly by the installer cannot occur; in addition, the risk of damage is lower (loss of small parts, penetration of dirt, etc.).

High protection degree

These devices are designed to be used in the toughest environmental conditions and they pass the IP67 immersion test acc. to EN 60529. They can therefore be used in all

environments where maximum protection degree of the housing is required. Due to their special design, these devices are suitable for use in equipment subjected to cleaning with high pressure hot water jets. These devices meet the IP69K test requirements according to ISO 20653 (water jets with 100 bar and 80°C).

External device monitoring

On request, the switch can be supplied with EDM function (External Device Monitoring). In this case, the switch itself checks the

proper function of the devices connected to the safety outputs. These devices (usually relays or safety contactors) must send a feedback signal to the EDM input, which checks that the received signal is consistent with the state of the safety outputs.

Compatibility with P-KUBE 2 safety handles

Anywhere it is necessary to monitor access to dangerous areas of machines or systems, the P-KUBE 2 safety handles can be used on doors or guards.

Together with the NG series RFID safety switches with guard locking, these door handles form an integrated locking system for guards that enables access control to dangerous areas. This combination allows a robust system to be created completely out of metal which is compact and conﬁgurable. It contains an RFID safety switch with centring pin for the door and optional emergency release button, an adjustable handle with LOCK OUT device and command devices.

The same article can be used on hinged doors with left and right stop as well as with sliding doors.
