Balluff BNS-819-D03-R12-100-10-FE Position Limit Switch

Balluff BNS-819-D03-R12-100-10-FE is a mechanical three-position position limit switch designed for end-of-travel sensing in automation equipment. The unit features three roller actuators and a snap-contact switching arrangement, delivering precise, repeatable switching at each of the three positions (1–3). Housed in an aluminum, anodized enclosure measuring 120 x 80 x 83 mm, it is intended for vertical installation with screw-terminal connections and an approach direction parallel to the attachment surface; the maximum approach speed is 60 m/min and the switch-spacing between positions is 12 mm. Electrically, the device is rated for up to 6 A with a rated operating voltage up to 250 VAC. It operates across a temperature range of -5 to 85 °C and carries IP67 protection, making it suitable for demanding industrial environments. The FE suffix denotes the function-indicator variant within Balluff's BNS 819 family. The BNS-819 series is designed for robust, mechanical, multi-position limit switching in industrial environments.
