The Pilz P2HZ X4P 24VAC 3N/O 1N/C (Part No. 777354) is a robust safety relay designed for monitoring and enforcing two-hand control systems in industrial environments. Specifically developed for two-hand device type III C applications, this relay ensures that hazardous machine functions can only be activated when both of the operator’s hands are engaged, eliminating the risk of accidental or premature machine start-up.

Operating on a 24 V AC supply voltage with a low power consumption of just 4 VA, the P2HZ X4P offers efficient and reliable operation in continuous-duty systems. Its compact and rugged design allows for easy integration into machine control panels while maintaining consistent performance across a variety of industrial settings.

The unit features a robust output configuration with three normally open (N/O) safety contacts and one normally closed (N/C) contact. The N/O contacts are designed for reliable disconnection of actuators such as motors, drives, or press mechanisms, ensuring that hazardous machine functions are immediately brought to a safe state. The additional N/C contact provides valuable auxiliary signalling or feedback to higher-level control systems, helping operators and maintenance personnel monitor the relay’s operational status.

A key application area for the P2HZ X4P is in press and forming operations, where two-hand control is a critical safety requirement. By enforcing the simultaneous actuation of two control buttons, the relay prevents one-handed or accidental operation, protecting operators from potentially life-threatening hazards associated with high-force machinery. Compliance with two-hand device type III C specifications ensures that the P2HZ X4P meets stringent international safety standards for this category of protective equipment.

The relay is also engineered with high-quality internal components that ensure long service life and resistance to the stresses of frequent actuation. Its clear terminal layout and compact design simplify installation and wiring, reducing setup times and minimising the potential for errors. Once installed, it provides dependable performance with minimal maintenance, ensuring both safety and productivity are maintained.

Typical industries where the P2HZ X4P is applied include metalworking, stamping, forming, packaging, and other automated production lines where two-hand control is essential. It is particularly valuable in machine environments where operators are working in close proximity to hazardous zones, and absolute certainty of safe operation is required.

In summary, the Pilz P2HZ X4P 24VAC 3N/O 1N/C combines energy-efficient AC operation, reliable safety contacts, robust two-hand control monitoring, and compliance with international safety standards. It is a trusted solution for safeguarding operators and ensuring safe operation of presses and other machinery, supporting both regulatory compliance and efficient industrial performance.
