Safety switch STM with guard locking and guard lock monitoringDue to its small design, the safety switch STM with plastic housing is particularly suitable for applications in which robustness is required in combination with small dimensions. Along with the variants with plastic actuating head, the STM is also available with a metal actuating head and cam. This variant is particularly suitable for applications that required high locking forces (up to 2000N). Features- Plastic housing with actuating head optionally made of metal or plastic
- Safety switch with separate actuator, guard locking and guard lock monitoring
- Separate switching contact for guard lock monitoring (1 switching contact) and door monitoring (2 switching contacts)
- Suitable for door radii down to minimum 300 mm
- High degree of protection IP 67

Connector Type: With Cable Entry | Safety switch STM |
- Actuating head optionally made of metal or plastic
- Mechanical release on the front
Mechanical releaseIs used for releasing the guard locking with the aid of a tool. To protect against tampering, the mechanical release is sealed with sealing lacquer. Solenoid operating voltage- AC/DC 24 V +10%, -15%
- AC 230 V +10%, -15%
Guard locking types| STM1 | Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the interlocking solenoid. | | STM2 | Open-circuit current principle, guard locking by applying voltage to the interlocking solenoid. Release by spring force. |
Switching elements| ÜK | For monitoring the guard locking (built-in solenoid) slow-action switching contact 1 NC |
| SK | For monitoring the door/actuator position |
Combinations available: | 222 | Slow-action switching contact 2 NC | | 242 | Slow-action switching contact 1 NC + 1 NO |
