3-Axis Safety Interlock Switch with Positive Break Contacts

Product Introduction

This 3-axis safety interlock switch is designed for industrial safety applications, featuring 1 auxiliary contact and 1 safety contact with positive break technology. Compliant with EN ISO 13849-1, it achieves Performance Level c (Category 1) in single-channel use and up to PL d (Category 3) in dual-channel configurations with a logic unit. The switch offers 2 million operations for NC contacts and 1 million for NO contacts, ensuring long-term reliability in harsh environments. With IP67 protection and a wide temperature range (-30°C to 80°C), it suits heavy-duty machinery and automated systems.
