Speed Sensor/Speed Pickup, Indoor, 2ppr, 24VDC, Reliable Way To Monitor Speed

Speed sensing of motors is an important requirement for industrial applications!

Our Dart Controls speed sensors can be used with our digital DC speed controls or as feedback to a plc/HMI/SCADA system,

Customers choose our Dart PU Series over encoders on the market for many reasons:  reliability, ease of installation, and value.  

Originally designed for the harsh, continuous duty of a pizza oven, this motor speed sensor is used around the world in a wide variety of applications with a very simple design.

This product may also be called hall effect sensors, hall effect pick-up and motor speed sensors.

If you have limited space that prevents physical contact with the motor shaft please consider using the OPU photoelectric optical pick-up.

The Dart PU series pick-up is a low cost and reliable way to monitor motor speed!
