The Pilz PIT ESC1 Safe Contact Block 1 N/C (Part Number: 400315) is a robust and reliable safety component designed to enhance the functionality of emergency stop (E-STOP) devices and other control and signal applications. As part of Pilz’s trusted safety portfolio, this contact block ensures dependable circuit interruption when safety devices are activated, contributing to both personnel protection and machinery safety in industrial environments.

At its core, the PIT ESC1 features a single normally closed (N/C) contact, which reliably opens when the E-STOP or related safety function is triggered. This straightforward yet vital design ensures that hazardous machine movements are interrupted immediately, reducing risks and supporting compliance with stringent safety requirements.

Built to meet EN 60947-5-1 standards, the contact block is specifically certified for E-STOP applications. This compliance provides assurance that the component is suitable for safety-related functions and meets international benchmarks for performance and reliability. By adhering to these standards, the PIT ESC1 plays an important role in ensuring systems remain audit-ready and compliant with machinery directives.

The contact material is AgNi (silver-nickel), chosen for its excellent conductivity, resistance to welding, and long mechanical endurance. This ensures the contact block maintains reliable performance across repeated switching cycles, even under demanding operating conditions. In safety-critical applications where reliability is paramount, the use of high-quality AgNi material ensures confidence in the device’s long-term durability.

The switching capacity of up to 250 V AC (AC15), along with utilisation categories for AC15 and DC13 as defined in EN 60947-5-1, makes the PIT ESC1 versatile for a wide range of control circuits. It can handle typical pilot control loads found in industrial automation, including relays, solenoids, and small actuators, ensuring dependable safety switching in both AC and DC systems.

In terms of practicality, the minimum contact current of just 1 mA allows the block to function effectively even in low-current applications, ensuring reliability across a spectrum of system designs. This versatility makes it a suitable choice for modern automation systems where mixed load requirements may exist.

The PIT ESC1 Safe Contact Block is widely used in industries such as manufacturing, packaging, automotive, and process automation, where emergency stop circuits and control devices form the foundation of machine safety. By providing a reliable and standards-compliant contact block, Pilz ensures that critical safety functions operate without compromise.

In summary, the Pilz PIT ESC1 Safe Contact Block 1 N/C (400315) is a dependable, standards-compliant solution for emergency stop and safety control applications. With its durable AgNi contacts, robust 250 V AC switching capacity, and compliance with EN 60947-5-1, it delivers the reliability and safety assurance needed in modern industrial automation environments.
