The Pilz PIT ESC3 Contact Block 1 N/O, part number 400310, is a high-quality contact element developed for use in Pilz control and signal devices, particularly in emergency stop and operator interface applications. Known for its durability and compliance with international safety standards, this contact block ensures reliable signal transmission and operational safety across a wide range of industrial environments.

At its core, the PIT ESC3 offers one normally open (N/O) contact, designed for straightforward integration into control circuits. With a minimum switching current of 1 mA, the contact block ensures reliable operation even in low-current signalling applications. This makes it especially suitable for safety and control circuits where precise and dependable switching is essential.

The contact material is AgNi (Silver-Nickel), a proven alloy that combines high conductivity with excellent resistance to wear and oxidation. This ensures that the contact block delivers a long service life while maintaining consistent switching performance, even under frequent actuation. In safety-critical devices such as emergency stop buttons, this durability translates into higher system reliability and reduced maintenance.

Built for demanding industrial environments, the PIT ESC3 is capable of operating across a wide ambient temperature range of –30 °C to +85 °C. This broad range ensures that the device can be deployed in varied conditions, from cold storage facilities to high-temperature production areas. Furthermore, the unit is rated for pollution degree 3 clearance and creepage, meaning it is robust enough to withstand challenging industrial atmospheres where conductive dust or moisture might otherwise affect performance.

Compliance with EN 60947-5-1 ensures that the PIT ESC3 is suitable for use in emergency stop (E-STOP) devices, meeting the strict standards required for machine safety. This makes it a vital component in safety circuits where operator protection is paramount. By ensuring reliable contact closure in E-STOP applications, the contact block plays a crucial role in preventing accidents and enhancing overall workplace safety.

Integration is straightforward, as the PIT ESC3 is designed to be used within the Pilz PIT range of control and signalling devices. It can be combined with E-STOP pushbuttons or other operator devices, enabling flexible configuration of control panels and safety systems.

In summary, the Pilz PIT ESC3 Contact Block 1 N/O (400310) is a compact, durable, and safety-compliant contact element that provides reliable switching performance in industrial control and safety applications. With its AgNi contact material, low switching current capability, broad operating temperature range, and compliance with international standards, it delivers the reliability and safety assurance expected from Pilz products. Whether integrated into emergency stop devices or other control panels, it is a dependable solution for safeguarding industrial processes.
