  • SP-16 16 CPR Optical Shaft Encoder

Overview

The SP-16 is a rugged, reliable, low cost optical incremental encoder that converts shaft angle, speed, and direction into real-time digital information. The shaft is torque-loaded to feel like a potentiometer. Two quadrature outputs provide 64 quadrature states per revolution (16 CPR x 4). The internal electronics and LEDs draw less than 27 mA from a single +5 V supply. Placed behind a knob on a front panel, the SP-16 offers these advantages over other types of man-to-machine...

Note:

Symmetry is a measure of the relationship between the high and low times of the A/B outputs in electrical degrees. Quadrature Delay is the phase lag or lead between channels A and B in electrical degrees. See "Output Waveform" for an illustration.

Product Description

The SP-16 is a rugged, reliable, low cost optical incremental encoder that converts shaft angle, speed, and direction into real-time digital information. The shaft is torque-loaded to feel like a potentiometer. Two quadrature outputs provide 64 quadrature states per revolution (16 CPR x 4). The internal electronics and LEDs draw less than 27 mA from a single +5 V supply. Placed behind a knob on a front panel, the SP-16 offers these advantages over other types of man-to-machine interfaces: direct rotary to digital conversion with no digit bobble, no contact wear and no mechanical stops. Limits can be defined by the system designer. No gearing is required for multi-turn operation. Non-torque loaded and ball bearing versions of the SP-16 are available for motion control applications.
