59145 Series - Flange Mount Reed Sensor

DataSheet:Littelfuse Reed Sensors 59145 datasheet

A flange mount reed sensor 28.57mm x 19.05mm x 6.35mm (1.125" x 0.750" x 0.259") with a choice of normally open, normally open high-voltage, normally closed or changeover contacts. Its case design enables screw or adhesive mounting. Wires exit from top right-hand side. Also available with left-hand exit (59150 series). Rated for operation up to 105°C. Capable of switching up to 265Vac/300Vdc at 10VA. Available with a range of sensitivity, cable length and connector options. Ideally suited for position and limit sensing, security, window and door alarm systems and linear actuator applications. Functions best with the 57145 or 57150 actuator.

Note: The 57145 and 57150 actuators are sold separately.

Features:

  • Magnetically-operated proximity sensor
  • Operates through non-ferrous materials such as wood, plastic or aluminum
  • Rated for high-temperature applications up to 105°C
  • Cross-slotted mounting holes for optimum adjustability
  • Customer-defined sensitivity
  • Choice of cable length and connector

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
  • Simple installation and adjustment

Applications:

  • Position and limit switching
  • Security
  • Linear actuators
  • Door switch
