59021-1-S

59021-1-S-03-A SENS | Series: 59021
info
A miniature, cylindrical reed sensor with a robust aluminum body 15.24mm x 5.10mm (0.600" x 0.201") with a normally open contact. Capable of switching up to 170Vdc at 10W. Available with a range of sensitivity, cable length and connector options. Well suited for position and limit sensing, security, level sensing and linear actuator applications. Functions best with the 57020 actuator.

Note: The 57020 actuator is sold separately.

  • Magnetically-operated proximity sensor with aluminum body
  • Operates through nonferrous 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
  • Fits nicely into small, confined spaces
  • Easy to install
  • Well suited for usage in high-moisture and contaminated environments
  • Noncontact 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 microcontroller voltage and current logic-level loads
