Phidgets PhidgetEncoder HighSpeed USB 4-Input

Description Phidgets PhidgetEncoder HighSpeed USB 4-Input Offers four digital inputs for reading limit switches or buttons Read up to four encoders simultaneously Works with all 0-5 V quadrature encoders Read at speeds of up to 250,000 quadrature cycles per second Draws 30 mA of current The Phidgets PhidgetEncoder HighSpeed USB 4-Input comes with four high-speed input interfaces with any 5 V quadrature encoder. A quadrature encoder is the most commonly used feedback device for a DC or stepper motor. With an encoder, you can keep track of how far your motor has turned, which then allows you to control the position and velocity in your code. This Phidget connects to your computer via USB.
