The Pilz PNOZ S6 24VDC 3N/O 1N/C (Part No. 750106) is a purpose-built safety relay designed for monitoring two-hand control devices in accordance with Type III C requirements. As part of Pilz’s proven PNOZsigma range, this relay provides the highest levels of reliability, ensuring that machines can only be activated safely when both operator hands are engaged simultaneously.

Operating on a 24 V DC supply with a low power consumption of just 3.5 W, the PNOZ S6 is highly energy-efficient while delivering dependable performance in continuous duty. Its compact and efficient design ensures straightforward integration into safety circuits, making it a cost-effective yet robust solution for machine safety applications.

At its core, the PNOZ S6 is engineered for two-hand control monitoring. In compliance with EN 574 Type III C standards, the relay ensures that both control buttons must be pressed simultaneously to initiate machine operation. If only one button is pressed or if one is released during operation, the relay immediately interrupts the control circuit. This functionality is critical for applications such as presses, stamping machines, or other machinery where operators must keep both hands away from hazardous zones during machine activation.

The relay provides three normally open (N/O) safety contacts for switching off hazardous functions and one normally closed (N/C) contact for feedback or signalling purposes. This combination of outputs offers flexibility in safety circuit design, supporting both direct control of actuators and system-level monitoring. By ensuring safe disconnection of machine power, the PNOZ S6 protects both personnel and equipment from accidental or unsafe operation.

Engineered for industrial durability, the PNOZ S6 is suitable for use in demanding environments. Its compliance with relevant international safety standards ensures that it can be integrated into systems requiring Performance Level e (PL e) to EN ISO 13849-1 or SIL CL 3 to IEC 62061, delivering maximum safety integrity for high-risk applications.

The design of the PNOZ S6 also supports easy installation and integration. Clear terminal assignments and a compact housing simplify wiring, reduce installation time, and minimise the risk of errors during commissioning. Its robust construction ensures long service life, reducing maintenance costs and minimising downtime.

Industries that benefit most from the PNOZ S6 include metalworking, automotive manufacturing, packaging, woodworking, and other process industries where machinery such as presses and stamping equipment pose significant risks. By enforcing strict two-hand operation, the PNOZ S6 ensures that operator safety is always maintained while keeping machinery efficient and productive.

In summary, the Pilz PNOZ S6 24VDC 3N/O 1N/C offers energy-efficient operation, standards-compliant two-hand monitoring, versatile outputs, and robust safety performance. It is an indispensable relay for ensuring operator protection in machine environments where two-hand controls are essential, helping businesses achieve both safety compliance and operational efficiency.
