siemens.com/safety-integrated

Reliable protective door monitoring is one of the most common safety
requirements that has to be provided for machines: hazardous machine
movements must be reliably brought to a standstill when a protective door is
opened. SIRIUS 3SK safety relays from Siemens provide the perfect solution for
every safety application on the basis of standard DIN EN ISO 14119: mechanical
protective door monitoring with standard and safety position switches, non­contact protective door monitoring with magnetically-operated switches,
protective door monitoring with non-contact RFID safety switches for the ultimate
protection against tampering.

Customer benefits/application

Mechanical protective door monitoring with SIRIUS 3SE5 position switches

- Modular design for versatile use (different actuator heads)

- Quick connect system and simple plug-in installation

- Suitable for higher currents

- Safe shutdown without action by the machine controller

- Absolute protection against electromagnetic interference

- 3D-coded actuators rule out the possibility of simple tampering

Non-contact protective door monitoring with coded 3SE6 magnetically­operated switches

- Two safety contacts + 1 signaling contact (diagnostics option)

- Long service life due to wear-free switching

- Particularly suitable for areas exposed to contamination, cleaning

and disinfecting

Non-contact protective door monitoring with 3SE63 RFID safety switches
offer additional benefits:

- Protection against tampering thanks to individual coding

- Extensive diagnostics functions provided by LEDs increase plant

availability

- High IP69K degree of protection for use in extreme environmental

conditions
