BERNSTEIN Tiny Ti2 Limit Plunger Switch, 1NO/1NC, 7N

The BERNSTEIN Tiny Ti2 Series Limit Plunger Switch is a compact and robust solution for precise position detection and safety monitoring in automation and process control systems. Housed in a self-extinguishing, fibreglass-reinforced PBT enclosure with a hinged PA 6.6 snap lid—both rated UL94V-0—it delivers exceptional durability and flame resistance in demanding industrial environments. Its ultra-compact design, with mounting measurements conforming to DIN EN 50047, allows for installation in tight spaces where reliable switching is critical.

Featuring a snap-action contact system with minimal hysteresis, this switch ensures a definitive, crisp actuation, preventing undefined statuses even with very slow plunger movement. This positive break action is crucial for safety applications. The switch offers a versatile 1NO/1NC (one normally open, one normally closed) contact configuration, with a maximum rating of 10A at 250V AC. The 7N operating force provides a reliable actuation threshold.

Engineered for safety and longevity, it includes Type-Zb galvanically isolated terminals and an M16 x 1.5 cable entry, facilitating secure and easy wiring. The actuator can be mounted in 4 positions at 90° increments, offering flexible installation. With an IP65 protection rating, it is fully protected against dust ingress and water jets, making it suitable for use in harsh conditions. The 2mm contact opening on the slow-action system complies with EN 81-1 standards for lift construction, underlining its suitability for critical safety monitoring.

This limit switch is an ideal component for implementing 2-channel safety monitoring systems, thanks to its positive break contacts and reliable performance. Its optimised size utilises proven terminal technology within the renowned Tiny Ti2 series from BERNSTEIN, a trusted name in industrial safety and sensing technology.
