59090 Series Image
A robust reed sensor with integral actuator magnet. Actuation occurs when a suitable vane passes through the slot between the magnet and reed switch. Choice of normally closed, high-voltage normally closed or changeover contacts. Capable of switching up to 265Vac/300Vdc at 10VA. Available with various cable length and connector options. Ideally suited for position and limit sensing, security, linear actuator, industrial process control and shaft rotation and heavy duty applications, such as off-road and heavy vehicles and farm machinery.

Features:

  • Sensor and magnet contained in a single housing
  • Operates when ferrous vane passes through slot
  • Quick and reliable single screw mounting with location feature
  • Options of normally closed, high-voltage normally closed or changeover contacts
  • Custom cable length and connector options available

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
  • Shaft rotation sensing
  • Industrial process control
  • Linear actuators

pdf icon Flow Sensing in Tankless Water Heaters Application Note

Reed switches and sensors are highly effective solutions for flow sensing applications that can be used for detecting the presence of fluid flow in a system or even measure the rate of fluid flow.

pdf icon Position and Level Sensing in Washing Machines

A most integral appliance in any home is a washing machine. Washing machines have helped made the chore of cleaning clothes quite effortless.

pdf icon Rice Cooker Lid Lock Application Note

This guide provides an introduction to magnetic sensing and options for value-added custom design packages.

pdf icon Capacitive Loads Application Note

When there is significant capacitance in a reed sensor reed relay or reed switch circuit the peak current and energy switched by the reed contacts should be considered.

pdf icon Inductive Load Arc Suppression Application Note

When a reed switch or reed sensor is used to control an inductive device (relay coil solenoid transformer small motor etc.)

pdf icon Reed Switch and Reed Sensor Activation Application Note

Although a reed switch can be activated by placing it inside an electrical coil many reed switches and reed sensors are used for proximity sensing and are activated by a magnet.

pdf icon Reed Switch Extended Shock Capabilities Application Note

The maximum shock specifications in the Littelfuse catalog are very conservative for most switches smaller than the DRxxxx type. T

pdf icon Vibration Testing and Precautions Application Note

Littelfuse tests sinusoidal vibration according to Mil. Std. 202G Method 204D Test Condition G (10 � 2000 Hz frequency sweep at 30 G or 0.06 inch double amplitude whichever is less).
