The Pilz PSEN sg2c Set Spring-Loaded Terminals (570777) is a dedicated accessory for the PSEN safety switch series with guard locking, designed to provide fast, reliable, and maintenance-free electrical connections. Compact and lightweight, the terminal set is built to meet the needs of modern safety applications where secure connectivity, easy installation, and long-term durability are essential.

Spring-loaded terminals offer a significant advantage over traditional screw-type connections. They ensure a secure and vibration-resistant hold, minimising the risk of loose wiring even under continuous machine operation or mechanical stress. By maintaining consistent electrical contact, the PSEN sg2c terminal set enhances the reliability of safety signals, which is critical in systems designed to protect both operators and machinery.

The set is designed for compact integration, with dimensions of 70 mm in height, 80 mm in width, and 20 mm in depth. At only 32 g net weight (34 g gross), it adds minimal bulk to the installation while delivering strong, stable connections. Its lightweight design makes handling, installation, and replacement straightforward, ensuring efficiency in both initial setup and maintenance tasks.

Built for use in standard industrial conditions, the PSEN sg2c terminals are rated for ambient operating temperatures between 0 °C and +55 °C. This makes them suitable for a wide range of production environments, from assembly and packaging lines to logistics and general machinery applications. Their robust design ensures stable performance across varying conditions, contributing to the long-term reliability of the overall safety system.

These terminals are particularly effective when used in combination with PSEN safety switches with guard locking. Such systems are commonly applied in machinery where access to hazardous areas must be controlled—for example, robotic cells, automated production lines, and packaging systems. The spring-loaded terminals ensure that wiring connections to the safety switches remain stable and maintenance-free, maximising system uptime and operator protection.

By simplifying installation, the PSEN sg2c terminals also reduce the risk of wiring errors, helping engineers save time during setup and ensuring that connections comply with the safety and reliability requirements of international standards such as EN ISO 13849 and IEC 62061.

In summary, the Pilz PSEN sg2c Set Spring-Loaded Terminals (570777) is a compact, durable, and efficient connectivity solution designed to support the reliability of safety switches with guard locking. With its spring-loaded design, compact dimensions, vibration-resistant hold, and straightforward integration, it provides an essential accessory for ensuring secure and consistent safety system wiring in industrial environments.
