Why Choose the Pizzato NS M4TE1SRK-N242 Safety Locking Switch?
The Pizzato NS M4TE1SRK-N242 is a sophisticated RFID safety switch with guard locking and integrated control devices designed for machine guarding, controlled access and operator control functions. Part of the Pizzato NS Safety Switch Series, it combines electronic guard monitoring, electromagnetic locking and machine-control functions within one robust industrial assembly.
This configuration is supplied without an actuator, allowing the appropriate compatible NS-series RFID actuator to be selected separately for the installation. The switch uses Pizzato's electronic safety architecture with dual safety inputs and outputs, separate actuator-inserted and actuator-locked signalling outputs and dedicated electromagnet-control inputs.
The NS M4TE1SRK-N242 uses the M working principle, with the actuator locked when the electromagnet is energised. Mode 3 provides differentiated monitoring of the inserted and locked guard conditions, while the locking mechanism delivers a maximum holding force of 2100 N. Two 12-pole M12 connectors provide convenient electrical integration with machine safety and control systems.
Key Advantages
- Combines RFID safety interlocking, guard locking and integrated control devices in one assembly.
- 2100 N maximum holding force provides secure retention of machine guards.
- M working principle locks the actuator when the electromagnet is energised.
- Mode 3 safety architecture provides differentiated monitoring of actuator insertion and locking.
- Dual safety inputs and outputs support integration with compatible safety controllers and safety PLCs.
- Separate signalling outputs provide clear actuator-inserted and actuator-locked status information.
- Two 12-pole M12 connectors provide a practical detachable wiring arrangement.
- Integrated control devices reduce the need for separate operator-control enclosures around the guard access point.

Integrated Guard Locking and Machine Control
The Pizzato NS series is designed for industrial machinery where reliable guard monitoring must be combined with controlled access to hazardous areas. RFID actuator detection electronically monitors the guard, while the electromagnetic locking mechanism provides secure mechanical retention when access must be prevented.
Mode 3 operation enables the NS M4TE1SRK-N242 to distinguish between actuator insertion and the fully locked condition through its electronic safety architecture. The integrated control-device arrangement further allows operator commands to be positioned directly at the guarded access point, helping create a compact and efficient machine-control installation.
Typical Applications
- Machine safety doors and guarded access points.
- Automated manufacturing and assembly cells.
- Robotic cells and automated production systems.
- Packaging and processing machinery.
- Conveyor and material handling equipment.
- Machine guards requiring local operator control devices.
- Industrial safety systems requiring monitored guard locking and emergency escape release.
