The Pilz PIT ES SET1S-5NS (Part No. 400453) is a robust and reliable control and signal device designed to provide dependable emergency stop (E-Stop) functionality in industrial safety applications. As part of the Pilz PIT series, it combines compliance with international standards, durable materials, and robust performance to safeguard both personnel and machinery in demanding environments.

One of its most important features is compliance with EN 60947-5-1, the international standard governing electromechanical control devices used in safety circuits. This ensures that the PIT ES SET1S-5NS is not only reliable but also meets the rigorous requirements necessary for integration into certified safety systems, guaranteeing operator protection in emergency conditions.

The switch incorporates AgNi (silver-nickel) contact material, chosen for its superior electrical conductivity and wear resistance. This material provides consistent performance over many switching cycles, significantly reducing maintenance requirements and extending the lifespan of the device. The reliability of AgNi contacts is particularly important in safety applications, where dependable switching performance is essential.

With a minimum contact current rating of just 1 mA, the PIT ES SET1S-5NS is capable of functioning in modern low-level signal circuits as well as in traditional higher-current applications. This flexibility makes it suitable for integration into a wide range of control systems, including those that rely on sensitive electronic components for monitoring and signalling.

Designed to withstand challenging conditions, the device operates reliably in ambient temperatures from -25 °C to +55 °C. This broad operating range allows it to perform in environments ranging from cold storage and outdoor facilities to hot industrial workshops. Furthermore, the switch is built to comply with pollution degree 3 clearance and creepage requirements, ensuring that it maintains safe and consistent operation even in areas subject to dust, humidity, or other environmental contaminants.

The PIT ES SET1S-5NS is engineered for straightforward integration into machine control systems, typically mounted on operator panels or enclosures where emergency stop devices must be easily accessible. Its compact yet durable design makes it simple to install while ensuring long-lasting reliability.

Applications for this device span across multiple industries, including manufacturing, robotics, packaging, process automation, and material handling, where safety controls are critical to maintaining compliance and protecting operators. By ensuring that machinery can be safely and immediately stopped in emergencies, the device plays a crucial role in preventing accidents and safeguarding equipment.

In summary, the Pilz PIT ES SET1S-5NS combines international standards compliance, durable AgNi contact design, low-current switching capability, and wide environmental suitability. It is a reliable and essential safety component designed to enhance machine protection and operator safety while providing flexibility and durability in modern industrial applications.
