A flange mount reed sensor 28.57mm x 19.05mm x 6.35mm (1.125" x 0.750" x 0.259") with integral terminal pins. Choice of normally open, normally open high-voltage or normally closed contacts. Its case design enables screw or adhesive mounting. Capable of switching up to 265Vac/300Vdc at 10VA. Available with a range of sensitivity options. Ideally suited for position and limit sensing, security, window and door alarm systems and linear actuator applications. Functions best with the 57125 actuator.

Note: The 57125 actuator is sold separately.

Features:

  • Magnetically-operated proximity sensor
  • Operates through non-ferrous materials such as wood, plastic or aluminum
  • Molded-in terminal pins accept push-on connector or wire-wrap
  • Case design allows screw-down or adhesive mounting
  • Customer-defined sensitivity

Benefits:

  • Well suited for usage in high-moisture and contaminated environments
  • Reed contacts last for millions of operating cycles under micro-controller voltage and current logic-level loads

Applications:

  • Position and limit switching
  • Security
  • Linear actuators
