- Versatile Contact Arrangement: Provides 1 normally closed (N/C) safety contact and 1 normally open (N/O) contact, enabling both reliable safety shutdown and diagnostic signalling.
- Standards-Compliant E-Stop Switching: Built to EN 60947-5-1 standards, ensuring suitability for emergency stop and operator safety circuits.
- Durable in Harsh Conditions: Operates within a wide -30 °C to +85 °C temperature range and features a pollution degree 3 rating for demanding environments.
- High-Quality Contact Material: Utilises AgNi (silver-nickel) contacts for excellent conductivity, resistance to wear, and long service life.
The Pilz PITESB1.4 Safe Contact Block 1N/C 1N/O (Part Number: 400307) is a robust and flexible control and signal device designed to ensure safe and reliable switching in emergency stop (E-Stop) applications and other safety-related functions. As part of the Pilz PIT range, it delivers the trusted reliability, durability, and compliance required for modern industrial environments.
This contact block is built around a dual contact configuration, consisting of 1 normally closed (N/C) safety contact and 1 normally open (N/O) contact. The N/C contact provides reliable interruption of safety-critical circuits, ensuring that power to hazardous machine operations is cut when an E-Stop is pressed or a safety event is triggered. The additional N/O contact can be used for auxiliary functions such as diagnostic signalling, system status indication, or triggering alarms, giving engineers flexibility to enhance system transparency and operator feedback.
The device is manufactured in compliance with EN 60947-5-1, the international standard for electromechanical control circuit devices and switching elements. This certification guarantees that the PITESB1.4 is suitable for use in emergency stop circuits, providing dependable performance and ensuring conformity with regulatory requirements for machine safety.
The contacts are made from AgNi (silver-nickel), a high-quality material that offers outstanding electrical conductivity and excellent resistance to wear, oxidation, and contact welding. This ensures the device maintains consistent switching performance even under frequent operation, reducing the need for maintenance and extending service life.
Engineered to withstand demanding environments, the PITESB1.4 can operate reliably within a broad ambient temperature range of -30 °C to +85 °C, making it suitable for both cold storage facilities and hot industrial shop floors. In addition, its pollution degree 3 classification for clearance and creepage distances ensures dependable performance in environments subject to dust, humidity, or contamination, which are typical in many heavy-duty industries.
The PITESB1.4 Safe Contact Block is ideal for integration into operator panels, E-Stop stations, safety gates, or machine-mounted control units. Industries such as automotive manufacturing, packaging, robotics, logistics, and process automation benefit from its robust design and flexibility. Its ability to provide both safety-critical switching and auxiliary diagnostic feedback makes it especially valuable in systems where uptime and quick fault identification are priorities.
In summary, the Pilz PITESB1.4 Safe Contact Block 1N/C 1N/O (400307) is a compact, durable, and standards-compliant device designed to enhance both safety and usability. With its versatile contact arrangement, silver-nickel contact material, wide operating temperature range, and compliance with international standards, it provides engineers and operators with a dependable solution for ensuring operator protection and maintaining efficient control of safety systems in challenging industrial environments.
