Weeder Technologies Quadrature Encoder cards with free Window's software

To track the position of a rotating shaft an absolute quadrature encoder sensor is used which in many cases incorporates an optical photo detector circuit or hall effect circuit to sense the rotation. Also called an incremental shaft encoder, or rotary encoder, these sensors output a pair of square waves which are 90 degrees out of phase allowing the rotational direction of the shaft to be detected as well as the degree of movement. Our small low-cost counter/timer cards which plug into the RS-232 or USB port of a computer contain specialized circuitry to interface with and decode these pulse streams. Software running on the computer will then be able to track the shaft rotation on a continuous basis.
