The Pilz PIT ESC2 Contact Block 1 N/C (Part No. 400320) is a robust control and signal device component, specifically designed to serve as part of an emergency stop (E-STOP) system. It provides a normally closed (N/C) contact configuration, ensuring that any activation of the emergency stop circuit immediately disconnects machine power, bringing hazardous equipment to a safe state.

Engineered in compliance with EN 60947-5-1, this contact block meets internationally recognised safety and performance standards. Its adherence to these requirements makes it a dependable choice for machine builders and plant operators who must achieve regulatory compliance while maintaining the highest levels of operator safety.

The use of AgNi (silver-nickel) contact material is a key feature of the PIT ESC2. AgNi contacts combine excellent electrical conductivity with outstanding resistance to mechanical wear and oxidation. This ensures consistent switching performance over a long service life, even in demanding industrial environments with frequent E-STOP activations.

One of the advantages of the device is its low-current capability, with a minimum switching current of 1 mA. This allows it to be used not only in traditional relay-based circuits but also in modern electronic systems where precise, low-level signals must be reliably detected. Its versatility ensures compatibility with a wide range of safety architectures.

The PIT ESC2 Contact Block is also built to withstand extreme ambient conditions, with an operating temperature range of -30 °C to +85 °C. This makes it suitable for use in cold storage facilities, outdoor installations, and high-temperature industrial environments, ensuring reliability in diverse applications. Additionally, it complies with pollution degree 3 clearance and creepage standards, meaning it can perform safely even in environments with dust, moisture, or other contaminants.

As part of the Pilz PIT emergency stop series, the PIT ESC2 Contact Block is designed for seamless integration with Pilz operator devices and control panels. Its compact design allows for easy installation, while its rugged construction ensures durability and reduced maintenance requirements.

Applications include manufacturing, packaging, robotics, process automation, material handling, and heavy machinery, where emergency stop functions are critical to ensuring the safety of operators and protecting equipment. By providing a dependable normally closed safety contact, the PIT ESC2 Contact Block ensures that hazardous machine functions are immediately halted when required.

In summary, the Pilz PIT ESC2 Contact Block 1 N/C (400320) offers compliance with international safety standards, durable AgNi contact technology, wide environmental tolerance, and compatibility with low-current control systems. It is a vital component in emergency stop systems, delivering reliable safety performance and long-lasting durability for modern industrial environments.
