The Pilz PIT ES SET8S-5C (part no. 400444) is a high-quality control and signal device specifically designed to serve as an emergency stop (E-STOP) switch in industrial applications. As part of Pilz’s well-regarded PITcontrol range, this unit combines compliance with international safety standards, robust construction, and reliable switching performance, making it a key component for safeguarding operators and machinery.

Built to meet EN 60947-5-1 standards, the PIT ES SET8S-5C ensures that emergency stop functions are executed safely and reliably. This certification underscores the device’s compliance with essential electrical and mechanical requirements for emergency stop devices, providing peace of mind that it will perform as expected in critical situations. When integrated into safety systems, it allows operators to halt hazardous machine operations immediately, minimising risks and preventing accidents.

The device’s contact design is a key strength. Using AgNi (silver-nickel) contact material, it delivers excellent conductivity, high resistance to welding, and strong durability, even under frequent operation. This ensures long service life and consistent performance, reducing maintenance needs while maintaining system reliability.

With a minimum contact current rating of 5 mA, the PIT ES SET8S-5C is well-suited for both standard and sensitive control circuits. This capability allows it to function reliably in applications where precise low-current switching is required, further broadening its usability across diverse machine types and safety architectures.

Environmental resilience is another advantage of the device. It is designed to operate within an ambient temperature range of -25 °C to +55 °C, making it suitable for a wide variety of industrial environments, from chilled storage facilities to warm production areas. Additionally, the pollution degree 3 clearance and creepage classification ensures safe and reliable performance even in areas where dust, dirt, or industrial residues may be present. This robustness allows the switch to maintain electrical safety and insulation integrity throughout its service life.

The PIT ES SET8S-5C is compact and designed for straightforward integration into control panels or operator stations. Its ergonomic design ensures user-friendly operation, allowing operators to trigger the emergency stop quickly and effectively. Combined with Pilz’s reputation for precision and quality, the device provides a reliable foundation for building compliant and efficient emergency stop systems.

In summary, the Pilz PIT ES SET8S-5C control and signal device is a robust, standards-compliant emergency stop solution designed to protect both people and machinery. With its silver-nickel contacts, low-current capability, wide operating temperature range, and adherence to EN 60947-5-1, it ensures safe, reliable, and efficient emergency stop functionality in industrial automation environments.
