Enabling Switches
HE1G-L Light Force Grip Enabling Switch
Key features:
• 3 position functionality (Off – On – Off) as required for manual robotic control
OverviewXW Series E-StopsInterlock SwitchesEnabling SwitchesSafety Control RelaysLight CurtainsAS-Interface Safety at Work
• Ideally suited for use as an enabling (aka “deadman”) switch for robotic cells
• Provides a high level of safety based on human behavioral studies that determine
personnel may squeeze OR let go when presented with a panic situation
• Contacts will not re-close when released from Off On (3 1) (per IEC60204-1; 9.2.5.8)
• Optional E-Stop switch built in
• Connection for conduit and cable strain relief built in
• IP66 waterproof sealing
• Meets ANSI RIA 15.06 robotics standards
• Optional momentary pushbutton
• Distinctive tactile feedback when shifting to position 2 (enabling position)
• Lighter operating force to on position
(Monitor Switch)
Variation
In addition to a monitoring switch, the HE1G grip switch is also available with an emergency stop switch or a momentary pushbutton. Screw terminal and wire-saving
internal connector models can be selected.

1: Yellow silicon rubber: Can be used in general factories. Remains exible at cold temperatures. Suitable to applications in a wide operating temperature range.
2: Gray NBR/PVC polyblend: Oil-proof. Suitable for environments subjected to machine oil and painting robot where silicon rubber cannot be used.

Terminals 1-2/A1-B1 and 3-4/A2-B2 are outputs of the 3-position enabling switch.
Terminals 5-6/A3-B3 are outputs of the monitor switch.
The above operation characteristics show when the center of the grip switch button is pressed. Because
two contacts are designed to operate independently, pressing the edge of the button turns on one
contact earlier than the other contact, causing a delay in operation. To avoid this, always press the
center of the button.
