Why Choose the Pizzato NG 2D7E421A-F31 Safety Switch?
The Pizzato NG 2D7E421A-F31 is a compact and robust RFID safety switch with solenoid guard locking, designed for reliable monitoring and protection of machine guards, access doors and hazardous areas in industrial automation systems. As part of the advanced Pizzato NG safety switch series, it combines coded RFID actuator detection with electronic safety monitoring and guard locking in a durable industrial housing.
The D7E operating principle uses an energised solenoid to lock the actuator, while the integrated escape release button provides a means of releasing the guard from inside the protected area when required. The supplied F31 actuator uses a high coding level, helping prevent manipulation by substituting an incorrect actuator and providing reliable guard identification.
The NG 2D7E421A-F31 is designed for demanding machine safety applications where non-contact coded detection and guard locking are required. Its robust construction, electronic safety outputs and high protection rating make it suitable for integration into modern industrial safety circuits and automated machinery.

Reliable Machine Guarding and Safety Control
The Pizzato NG series combines RFID actuator recognition with electronic safety monitoring and guard locking to provide a dependable interface between machine guards and safety control systems. The non-contact RFID system detects the coded actuator while the electronic safety outputs communicate the guard status to a safety PLC or suitable safety module.
The NG 2D7E421A-F31 uses the D7E energised-solenoid locking principle and includes an escape release button for personnel inside the guarded area. Its F31 actuator has a high coding level and is individually associated with its corresponding switch, helping prevent another actuator from being recognised unless a new association procedure is performed. The electronic architecture allows the device to be incorporated into modern machine safety circuits requiring reliable guard monitoring and locking.
Typical Applications
- Machine guarding and safety access doors.
- Industrial production and processing machinery.
- Automated manufacturing systems.
- Packaging and material handling equipment.
- Robotic cells and automated workstations.
- Machines with hazardous movement or stored energy.
- Safety circuits requiring RFID-coded guard locking.
- Industrial machinery requiring non-contact electronic guard monitoring.
