Hall-Effect Pick Ups
A Hall effect pickup, or hall effect sensor, is a transducer that responds to a magnetic field. Hall sensors can sense proximity, positioning, speed and current as they detect the presence of a magnetic field and produce an output voltage.

Hall effect pickups are commonly used to detect the presence of magnetic objects in switches, pistons or valves. In this capacity, hall sensors are placed at one or both ends of a device to determine the position of the magnet and help identify when a switch is open or closed, or act as the switch themselves.

Hall sensors are also used to detect the speed and position of the rotor in a brushless DC motor. Providing position and speed information, pickups assist with DC motor control, speed regulation, and braking systems.

PU-E Series Image
  • Mounts Directly to Shaft
  • 5~24 VDC
  • 1 to 20 Pulses Per Revolution
  • Quadrature Pick Up Available
  • Stainless Steel Ball Bearing
The PU-E Series pick-up is an economical and reliable way to monitor motor speed. Its patented design provides ease of installation in otherwise difficult to reach areas. The PU-E pick-up operates at a 5 to 24 volt level producing a sharp square wave output, which may be fed into Dart's field programmable tachometer, closed-loop control, counter, or any other digital device.
The PU-E pick-up series also includes a quadrature model to monitor both motor speed and direction by providing two square wave output signals 81 degrees out-of-phase.
HESS Series Image
The ARCJ kits with the HESS sensor require an external +8 to +30 VDC power source. 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 when the sensor is not detecting metal. The sensor face can be mounted flush into metal panels. The case is stainless steel and is supplied with 10 feet (3 M) of cable. The stranded shield wire is not connected to the sensor circuit or the case.
