The Pilz PITESB1.3 Safe Contact Block 2N/C 1N/C (Part Number: 400304) is a precision-engineered control and signal device designed to ensure the reliable transmission of safety signals in emergency stop (E-Stop) and related safety applications. As part of the trusted Pilz range of operator interface and control devices, this safe contact block provides dependable, standards-compliant performance in even the most demanding industrial environments.

One of the key strengths of the PITESB1.3 lies in its contact configuration. It is fitted with 2 normally closed (N/C) safety contacts, which provide redundancy and reliable monitoring of critical safety functions. This dual-channel configuration ensures that if one contact fails, the other continues to safeguard the system. In addition, it includes an auxiliary N/C contact that can be used for diagnostic or signalling purposes, such as alerting higher-level control systems or maintenance teams when an E-Stop has been triggered.

Engineered to comply with EN 60947-5-1, the international standard governing control circuit devices and switching elements, the PITESB1.3 ensures consistent safety performance in line with global industry requirements. This compliance gives machine builders and operators confidence that their systems meet both legal and operational safety obligations.

The contact material, made from AgNi (silver-nickel), enhances durability and reliability. Silver-nickel provides excellent electrical conductivity while resisting welding, pitting, and mechanical wear that can occur with frequent actuation. This ensures long-term stable performance, even in environments where E-Stops may be operated repeatedly.

With an operating temperature range of -30 °C to +85 °C, the PITESB1.3 is designed for resilience in diverse industrial environments. Whether in cold storage facilities, outdoor installations, or hot production lines, it maintains reliable performance across extreme temperature conditions.

Additionally, the device is built for demanding electrical environments, featuring a pollution degree classification of 3 for clearance and creepage distances. This means it is suitable for use in environments with significant airborne contamination, such as dust or humidity, further underlining its rugged design.

The PITESB1.3 is ideally suited for use in industries such as automotive manufacturing, robotics, packaging, logistics, and process automation, where operator safety and machine reliability are paramount. Its role in E-Stop systems, safety gates, and interlocks ensures that hazardous machine functions are quickly and reliably disabled when required, protecting both personnel and equipment.

In summary, the Pilz PITESB1.3 Safe Contact Block 2N/C 1N/C (400304) is a durable and reliable safety component designed to enhance the integrity of emergency stop and safety circuits. With its robust contact configuration, standards compliance, wide operating temperature range, and silver-nickel contact material, it provides engineers with a dependable solution for maintaining machine safety across a broad spectrum of industrial applications.
