59030 Series - Firecracker Reed Sensor

59030 Series Image
A cylindrical reed sensor 38.1mm x 6.22mm (1.50" x 0.245") with a choice of normally open, normally closed or changeover contacts. Capable of switching up to 265Vac/300Vdc at 10VA. Available with a range of sensitivity and cable length options. Ideally suited for position and limit sensing, security, level sensing and linear actuator applications. Functions best with the 57030 actuator.

Note: The 57030 actuator is sold separately.

Features:

  • Magnetically-operated proximity sensor
  • Operates through non-ferrous materials such as wood, plastic or aluminum
  • Hermetically sealed contacts
  • Options of normally open, normally closed or single-pole-double-throw
  • Customer-defined sensitivity
  • Custom cable length and connector options available

Benefits:

  • Quick and easy to install
  • Well suited for usage in high-moisture and contaminated environments
  • Non-contact solution, aesthetically more appealing than push-button or lever mechanical-type switches
  • Ideal for battery-powered applications as the contacts do not draw power when in the non-activated state
  • Reed contacts last for millions of operating cycles under micro-controller voltage and current logic-level loads

Applications:

  • Position and limit switching
  • Security
  • Level sensing
  • Linear actuators
