Model HESS Hall Effect Speed Sensor
Brand: Red Lion Controls
The Hall Effect Speed Sensor (HESS) is ideal for sensing steel gears or other ferrous targets from 0 to 10 kHz.
This sensor does not have a minimum threshold speed as does a magnetic pickup sensor.
However, when the sensor is first powered up, the output state is indeterminate (Hi or Lo) when the sensor is not detecting metal.
The unit operates from a 8-30 Vdc power supply and is reverse polarity protected.
The sensor face can be mounted flush into metal panels.
The case is stainless steel and is supplied with 10 feet (3 meters) of cable.
The stranded shield wire is not connected to the sensor circuit or case.
