The Pilz PIT ES SET9U-7 – 400457 is a rugged and reliable control and signal device designed for use in safety-related applications, particularly as part of emergency stop (E-STOP) systems. Engineered to Pilz’s high-quality standards, it provides precise switching performance, environmental resilience, and compliance with international safety requirements, making it ideal for use across a wide variety of industrial sectors.

This unit is specifically built for emergency stop functionality, meeting the stringent requirements of EN 60947-5-1, the international standard governing E-STOP devices. Compliance with this standard ensures that the PIT ES SET9U-7 provides safe and dependable interruption of hazardous machine functions during an emergency, safeguarding both operators and equipment.

One of its notable features is its low minimum contact current rating of just 1 mA, which allows it to operate reliably in low-power control circuits. This makes it highly suitable for modern automation systems that increasingly depend on sensitive, low-voltage electronics. In addition, its AgNi (Silver-Nickel) contact material provides superior conductivity and resistance to wear, ensuring long service life and consistent performance even under demanding operational conditions.

The PIT ES SET9U-7 is also designed to withstand challenging environmental conditions. With an ambient operating temperature range from -30 °C to +70 °C, it is suitable for applications in both cold storage environments and high-temperature industrial settings. Its pollution degree 3 classification further demonstrates its ability to operate reliably in industrial atmospheres where dust, moisture, or other contaminants may be present.

Built with durability and reliability at its core, this control device ensures consistent performance during repeated actuation, an essential feature for emergency stop applications that demand flawless operation every time. Its robust design makes it a trusted component for machine builders, system integrators, and maintenance teams looking to enhance operator safety and meet regulatory requirements.

Typical applications include use in machinery where emergency stop buttons are required, such as packaging systems, manufacturing lines, processing plants, robotics, and material handling equipment. By providing reliable and standards-compliant control, the PIT ES SET9U-7 ensures that operators can halt dangerous machine functions instantly, reducing risks and preventing accidents.

In summary, the Pilz PIT ES SET9U-7 – 400457 offers a dependable and compliant solution for emergency stop systems. With its low contact current capability, AgNi contact durability, wide temperature tolerance, and adherence to EN 60947-5-1, it is a robust, long-lasting, and standards-compliant choice for ensuring operator safety in industrial environments.
