Current Sensors Line Guide

current sensors

Past, future, and current excellence. Honeywell offers a wide variety of current sensors to monitor alternating (ac) or direct (dc) current. From digital output detectors sensing a few hundred milliamps to linear sensors monitoring over one thousand amps, our comprehensive line provides superior performance at a reduced cost. 

As well as the advantages you'd expect from an experienced provider:

  • Decades of engineering expertise
  • Thru-hole design
  • Fast response times
  • Output voltage isolation from input
  • Minimum energy dissipation
  • Enhanced reliability with adjustable performance and built-in temperature compensation
