Honeywell SNDH-H Hall-Effect Speed Sensors

Honeywell SNDH-H Hall-Effect Speed Sensors use magnetically biased Hall-effect ICs to detect the movement of ferrous metal targets accurately. These sensors feature rugged probe-type packages, stable performance across temperature and air-gap ranges, and zero-speed detection for low-RPM systems. The SNDH-H hall-effect speed sensors operate within a temperature range from -40°C to 150°C and a maximum supply voltage range from 4Vdc to 24Vdc. These components provide a maximum supply current range from 6mA to 14mA and an output leakage current of 10µA. Typical applications include pump speed, motor speed, transmission speed, and vehicle speed.
