Schmersal Magnetic Safety Switch, 2NO/NC, 24V DC - BNS33 Series - BNS 33-12ZG-2187-2M
Safeguard hazardous areas in your workplace and protect your workforce from harm with this non-contact safety switch from Schmersal. The device functions by sensing whether a coded magnetic actuator is in range. For clarity, it has an LED indicator that turns on when a guard door is open and turns off when it's closed. Actuator coding stops the switch from being bypassed by a standard magnet, so is an effective security measure to prevent tampering. A matching actuator (198-7863) is available separately.
