The Pilz PNOZ X Set Spring-Loaded Terminals P3+P4 (Part Number: 374291) is a dedicated connection accessory designed to simplify wiring and enhance reliability within the Pilz PNOZ X safety relay series. Built to Pilz’s high standards of quality and durability, this set of spring-loaded terminals ensures secure electrical connections that remain stable under the stresses of industrial environments.

One of the primary benefits of the PNOZ X Spring-Loaded Terminals is their secure connection technology. Unlike screw terminals, which may loosen over time due to vibration, temperature fluctuations, or prolonged use, spring-loaded terminals maintain constant contact pressure. This guarantees consistent signal transmission, minimises the risk of wiring faults, and eliminates the need for frequent retightening, making them ideal for long-term, maintenance-free operation.

The terminal set includes the P3 and P4 configurations, designed for seamless integration with the PNOZ X relay range. This ensures engineers and maintenance teams can achieve straightforward, tool-free installation. By reducing setup complexity, the terminals help shorten commissioning times and simplify maintenance interventions, ultimately improving system availability and reducing downtime.

Despite its small footprint, the accessory plays a crucial role in maintaining the integrity of safety systems. Weighing just 27 g (net) and 28 g (gross), it is lightweight yet robust, offering reliable performance without imposing additional mechanical or spatial demands on the control cabinet. This makes it particularly well-suited for modern, compact automation environments where efficiency and space-saving design are priorities.

The PNOZ X Set Spring-Loaded Terminals P3+P4 is not only about convenience—it also directly supports safety compliance. By ensuring dependable electrical contact, it contributes to the overall reliability of Pilz safety relays, which are widely used for monitoring emergency stops, safety gates, two-hand controls, and other critical safety functions. Its precision design helps ensure that these safety circuits function exactly as intended, protecting personnel and machinery in line with international safety standards.

Applications for this accessory span across all industries where PNOZ X relays are used, including manufacturing, packaging, logistics, and process automation. In every case, the spring-loaded terminals provide a practical, long-lasting connection solution that reduces maintenance burden and increases operator confidence in system reliability.

In summary, the Pilz PNOZ X Set Spring-Loaded Terminals P3+P4 (374291) offers an essential combination of secure connectivity, quick installation, and compatibility with PNOZ X safety relays. With its robust spring technology and user-friendly design, it enhances both the reliability and efficiency of safety systems, making it an indispensable accessory for safe and effective industrial automation.
