RFS5

  • Limit value switch for frequency input sinusoidal signal

  • Simple application; for harsh environments

  • Limit value adjustable by drum scale

  • Normally open or normally closed version

  • Compact and robust construction

  • Operating status indication by integrated LED

Limit-value switches of type RFS5, monitor electrical measured variables. The integrated relay switches when the actual value present reaches the set target value. Normally open devices can also be equipped with a self-latching feature as an option. Its compact and robust design, as well as the relevant shipbuilding approvals, make this product ideal for marine applications.
