The Pilz PIT ES SET8S-5 (part no. 400443) is a robust control and signal device engineered to provide dependable emergency stop (E-STOP) functionality in safety-critical industrial environments. As part of the well-established Pilz PIT series, it combines compliance with international standards, rugged construction, and precise switching capability, making it a trusted solution for safeguarding both operators and machinery.

Built to conform with EN 60947-5-1, the PIT ES SET8S-5 ensures its design and performance meet stringent requirements for emergency stop devices. This compliance provides machine builders and operators with confidence that the device can be relied upon to safely interrupt hazardous machine functions whenever required, supporting full regulatory adherence.

At the heart of the device’s reliability are its AgNi (silver-nickel) contacts. Known for their excellent conductivity and durability, AgNi contacts are resistant to electrical wear and arcing, making them ideal for frequent actuation scenarios. This ensures long service life, stable switching performance, and reduced maintenance needs in demanding industrial applications.

The device also supports a minimum switching capacity of 1 mA, making it suitable for use in low-power safety control circuits. This precision is particularly important in modern automation systems where fine control and accurate feedback are necessary. Despite its ability to handle low-current switching, the device remains robust enough to perform consistently in heavy-duty safety roles.

Environmental resilience is another defining feature of the PIT ES SET8S-5. With an operating range of -30 °C to +70 °C, it remains fully functional in both extreme cold and high-temperature environments. This wide tolerance ensures suitability for industries such as automotive, packaging, material handling, and process industries, where fluctuating or harsh operating conditions are common. Additionally, its design is rated for pollution degree 3, meaning it can withstand environments with conductive dust or moisture, further broadening its application scope.

Compact and easy to integrate, the PIT ES SET8S-5 is designed for use in control panels, operator stations, and machine housings. Its ergonomic layout ensures straightforward operator access in emergencies, while its compatibility with other Pilz safety relays and controllers enables it to be part of a fully modular and scalable safety system.

In practice, the device is widely used as part of emergency stop stations and operator control panels, providing operators with a reliable means of quickly halting hazardous movements. By ensuring fast and accurate switching, it helps protect personnel, reduce machine downtime, and prevent damage to valuable equipment.

In summary, the Pilz PIT ES SET8S-5 is a durable, standards-compliant emergency stop device that combines wide environmental tolerance, AgNi contact reliability, low switching current capability, and ergonomic integration. It represents a practical and proven choice for ensuring operator safety and regulatory compliance in diverse industrial applications.
