GEL 2474 – 1 or 2 channel speed sensor

GEL 2471 speed sensor

The GEL 2474, 1- or 2- channel speed sensor delivers a square-wave, current or voltage output and provides safe detection of very slow rotation from 0 Hz without pulse loss and for high-speed rotation up to 25 kHz. The speed sensor operates based on the magnetic measurement principle. It is maintenance- and wear-free and operates contact […]
