Reed Switch and Hall Chip based Magnetic Proximity Sensors


   Magnetic Sensors

Standex Electronics designs and builds magnetic proximity sensors for a wide range of markets and applications. The basic sensing element for most applications is the hermetically sealed reed switch or hall chip. Other technologies are used as the application dictates.

Hall Chip based Proximity Sensor features:

  • Digital Switching

  • Miniature Packages

  • True Zero Speed

  • Non Contact Sensing

Reed Switch based Sensor Features:

  • Hi-Rel Switching - hermetically sealed contacts - billions of operations switching low level loads.

  • No external power required

  • Power Switching - direct switching of power loads with up to 2.5 amp DC inrush

  • Wide actuation Distance - reliable actuation at up to one inch for certain applications

  • Low cost - very competitive with other technologies
