How We Outperform The Rest

Available Only at HSI Sensing

Spot On™

  • No-touch sensing to ferrous target or magnet.

  • Consumes no power for either switching or sensing, and no signal loss.

  • Stable contact resistance even in high power, high voltage applications.

  • Not gravity sensitive.

  • Normally open or normally closed contacts.

  • Data-coded for traceability.

  • Vacuum-sealed with no moving magnets or parts for reliability in extreme environments.

  • Epoxy-sealed for a double layer of protection against shock, vibration and stress.
