The Pilz PIT ES SET1S-5 (Part No. 400432) is a robust and reliable control and signal device designed to serve as an emergency stop (E-STOP) unit in modern industrial safety systems. As part of Pilz’s trusted PIT product range, it provides operators with a dependable and easy-to-use safeguard to immediately halt machinery in hazardous situations, protecting both personnel and equipment.

Built to meet EN 60947-5-1, the PIT ES SET1S-5 complies with international safety standards, making it suitable for integration into global machine designs. This ensures machine builders and plant operators achieve compliance with safety directives and regulations while maintaining operational reliability. The emergency stop function ensures that hazardous machine movements are interrupted immediately, reducing risks in environments where quick intervention is critical.

The device is equipped with AgNi (silver-nickel) contact material, selected for its high electrical conductivity and resistance to wear. This ensures reliable performance across frequent switching operations, extending service life and reducing maintenance demands. The use of AgNi also supports stable performance in demanding environments where durability is essential.

With a minimum contact current rating of just 1 mA, the PIT ES SET1S-5 is well-suited to modern safety and automation systems, including sensitive low-voltage control circuits. This feature ensures compatibility with both advanced electronic systems and traditional electromechanical circuits, offering flexibility for a broad range of applications.

The ambient temperature range of -30 °C to +70 °C is another defining strength. This wide range allows the device to function reliably in extreme environmental conditions, such as cold storage facilities, outdoor applications, or high-temperature production areas. Furthermore, compliance with pollution degree 3 clearance and creepage standards ensures that the device maintains reliable performance even in areas subject to dust, humidity, or other airborne contaminants.

The PIT ES SET1S-5 is designed for easy integration into control panels and operator stations. Its rugged construction, combined with Pilz’s renowned reliability, ensures consistent performance over long operating lifespans. This helps reduce downtime and supports high overall equipment availability.

Typical applications for the PIT ES SET1S-5 include manufacturing, robotics, packaging, automotive production, material handling, and process automation. In these environments, reliable emergency stop devices are not just a regulatory requirement but a fundamental aspect of safe machine operation.

In summary, the Pilz PIT ES SET1S-5 (400432) delivers certified E-STOP compliance, AgNi contact durability, wide environmental resilience, and compatibility with low-current control systems. It is a dependable and versatile solution for ensuring operator safety, reducing risks, and maintaining compliance with global safety standards in modern industrial environments.
