Reed Sensors for Position and Limit Sensing 59140 Series

Littelfuse offers its 59140 series miniature flange-mount reed sensors suitable for position and limit sensing, security system switches, linear actuators, and door switches

Image of Littelfuse Reed Sensors for Position and Limit Sensing 59140 SeriesLittelfuse 59140 series are miniature flange mounting reed sensors occupying only 3.22 cm2 (0.500 in.2) board space. They offer a choice of normally open, normally open high voltage, normally closed or changeover contacts. Their case design enables screw or adhesive mounting and the wires exit from top right hand side. They are also available with left hand exit (59141 series). The sensors are capable of switching up to 265 VAC / 300 VDC at 10 VA. The 59140 series function best with the matching actuator 57140-000.

Note: The 57140 actuator is sold separately.

Features
  • Magnetically operated position sensor
  • Customer-defined sensitivity option
  • Choice of cable length and connector
Applications
  • Position and limit sensing
  • Security system switches
  • Linear actuators and door switches
Benefits
  • Hermetically sealed, magnetically operated contacts continue to operate long after optical and other technologies fail due to contamination
  • No standby power requirement
  • Operates through non-ferrous materials such as wood, plastic or aluminum
  • Excellent for switching micro-controller logic level loads
