NX B31AE1SMK-F60 Pizzato NX Series RFID safety switch

Why Choose the Pizzato NX B31AE1SMK-F60 RFID Safety Switch?

The Pizzato NX B31AE1SMK-F60 is a compact RFID safety switch with guard locking designed for monitoring and controlling access through movable machine guards and safety doors. Part of the Pizzato NX series, it combines RFID actuator detection, a bistable locking mechanism and electronic safety outputs in a compact format for machinery where installation space is limited.

This configuration is supplied with the VN NX-F60 universal actuator with low coding level. The switch uses Mode 1 bistable operation, with safety outputs OS1 and OS2 activated when the actuator is inserted and locked. The B31 configuration features factory-programmed actuator recognition and provides two safety inputs, two safety outputs, status signalling and solenoid control inputs for integration into compatible safety circuits.

The AE auxiliary-release arrangement combines a hexagonal-key release at the front with an escape-release pushbutton at the rear. An axial M12 12-pole stainless-steel connector, RGB LED illuminated cover, IP67 / IP69K protection and an actuator holding force of up to 6000 N make the NX B31AE1SMK-F60 a versatile solution for demanding machine-safety installations.

Key Advantages

• Compact RFID safety switch with integrated guard locking for space-constrained machinery.
• Supplied with a VN NX-F60 low-level coded universal actuator.

Compact RFID Guard Monitoring with Bistable Locking

The Pizzato NX B31AE1SMK-F60 uses RFID technology to detect its associated actuator while a bistable solenoid mechanism controls the guard-locking function. In Mode 1, the redundant OS1 and OS2 safety outputs are activated when the actuator is both inserted and locked, allowing compatible safety control equipment to monitor the required safe guard condition.

The VN NX-F60 actuator provides low-level coding and is supplied with this configuration. For guarded areas that may be entered by personnel, the AE release arrangement combines an externally accessible hexagonal-key release with a rear escape-release pushbutton, while the multicolour RGB LED cover provides convenient visual indication of switch status.

Typical Applications

• Compact industrial machine guards and safety doors.
• Robotic cells and automated manufacturing systems.
• Guarded areas requiring an internal escape-release facility.
• Packaging and processing machinery.
• Assembly and automated production equipment.
• Material handling and conveyor systems.
• OEM machinery requiring RFID guard monitoring and locking in limited installation space.
