Telemecanique VY1A66105 Hall Effect Current Sensor

The Telemecanique VY1A66105 Hall Effect Current Sensor (HAK 150-S S2) is designed to mount inside Altivar 66 variable speed drives to provide accurate motor current measurement for drive control and protection. It uses open-loop Hall-effect technology, accepts AC or DC primary current, and provides a voltage output for feedback with a nominal current rating of 150 A RMS. Compatible with Altivar 66 drives, it supports ATV66D54N4 through ATV66D79N4 and ATV66D33M2 through ATV66D46M2 models. In industrial automation, it is commonly used in conveyors, pumps, fans, compressors, HVAC equipment, mixers, and material handling machinery where precise motor current sensing enables closed-loop control, overload protection, and drive diagnostics.
