The Pilz PIT ES SET2S-5C (Part No. 400435) is a robust control and signal device engineered to provide dependable emergency stop (E-Stop) functionality in industrial safety systems. Designed as part of Pilz’s trusted PIT series, it ensures that operators can bring machinery to a safe stop quickly and reliably during hazardous situations, protecting both personnel and equipment.

Built in compliance with EN 60947-5-1, the PIT ES SET2S-5C meets the stringent international standards required for emergency stop devices. This guarantees safe operation in line with legal and regulatory requirements, providing assurance to machine builders and plant operators alike. By integrating seamlessly into safety circuits, it ensures hazardous machine functions are immediately deactivated when triggered, reducing accident risks significantly.

The device employs AgNi (silver-nickel) contact material, known for its superior electrical conductivity, durability, and resistance to oxidation. This makes it ideal for repetitive switching operations, providing consistent performance and a long service life. AgNi contacts ensure that even under frequent actuation cycles, the switch maintains reliable functionality—critical in emergency stop applications where performance cannot be compromised.

The minimum contact current rating of 5 mA allows the device to function effectively in modern control environments, including low-level electronic systems where traditional E-Stop switches may struggle to perform reliably. This flexibility ensures compatibility with both sensitive control electronics and higher-current circuits, making it suitable for a wide variety of safety architectures.

Environmental resilience is another key strength of the PIT ES SET2S-5C. It is designed to operate in ambient temperatures from -25 °C to +55 °C, making it adaptable to a wide range of industrial conditions—from refrigerated areas and outdoor installations to warmer factory floors. Compliance with pollution degree 3 clearance and creepage requirements further ensures reliable operation even in environments where dust, humidity, or other contaminants may be present.

The device’s compact and practical design allows for straightforward installation into control panels, operator stations, or machine enclosures. Its durability ensures low maintenance requirements and reduced downtime, supporting long-term cost efficiency.

Applications for the PIT ES SET2S-5C include manufacturing, robotics, packaging, material handling, and process automation industries, where emergency stop systems are mandatory. By enabling immediate shutdown of machinery, the device plays a vital role in preventing workplace accidents, safeguarding operators, and protecting equipment from damage.

In summary, the Pilz PIT ES SET2S-5C combines compliance with international safety standards, durable AgNi contacts, low-current switching capability, and wide environmental tolerance. It is a reliable and versatile emergency stop device that enhances both safety and efficiency in industrial environments, making it a trusted choice for machine builders and plant operators committed to maintaining the highest safety standards.
