The Pilz PNOZ X Set Spring-Loaded Terminals P1+P2, part number 374290, is a dedicated accessory designed for use with the trusted PNOZ X series safety relays. Offering a compact, durable, and user-friendly design, this terminal set provides an efficient and reliable means of connecting safety relays into industrial control systems.

At its core, the P1+P2 set uses spring-loaded connection technology, which offers several advantages over traditional screw terminals. By eliminating the need for tightening, spring connections allow for fast, tool-free installation while ensuring that wires remain securely fixed in place. The spring mechanism automatically applies consistent pressure, creating a stable and vibration-resistant connection. This feature is particularly beneficial in industrial environments where machinery is subject to constant movement and vibration, conditions that can otherwise loosen conventional screw terminals over time.

With a net weight of only 13 g (gross weight 15 g), this accessory is lightweight yet robust. Its small footprint makes it ideal for compact control panels and applications where space is limited. Despite its minimal size, it is engineered to withstand the demands of continuous use, delivering long-term reliability and safety performance.

The plug-in terminal design further enhances usability. Once wired, the terminal blocks can be plugged directly into compatible PNOZ X safety relays. In the event of maintenance or relay replacement, the plug-in format allows for quick disconnection and reconnection without rewiring. This significantly reduces downtime during service, ensuring higher productivity in environments where safety and operational continuity are equally critical.

Designed to meet Pilz’s rigorous quality standards, the P1+P2 terminal set provides dependable electrical performance across diverse safety applications. It is particularly suited to safety circuits involving emergency stops, safety gate monitoring, light curtains, or two-hand control systems—anywhere a secure and stable connection is essential for maintaining operator and machine safety.

The use of spring-loaded terminals also contributes to long-term cost efficiency. By reducing wiring time, minimising the need for tools, and preventing common issues such as loose connections, these terminals lower both installation and maintenance costs. Their reliability ensures fewer connection-related faults, supporting continuous uptime and reducing unplanned service interventions.

In summary, the Pilz PNOZ X Set Spring-Loaded Terminals P1+P2 (374290) is a practical, compact, and highly reliable accessory for the PNOZ X safety relay range. Its spring-loaded technology ensures fast installation and secure, vibration-resistant connections, while the plug-in design simplifies maintenance and replacement. By combining convenience, durability, and trusted Pilz quality, it provides an essential solution for enhancing the efficiency and reliability of safety-critical systems in industrial environments.
