The AEDR-9940 is a versatile three-channel reflective optical encoder offering selectable and programmable options for digital or analog differential outputs. It can interface directly with external interpolators in analog mode, providing Sine+, Sine-, Cos+, Cos-, I+, and I- outputs. In digital mode, it delivers two-channel (AB) quadrature outputs and a third channel digital index output, compatible with TTL signal processing circuitry for easy integration. Designed for a wide operating temperature range and small form factor, it is suitable for commercial, industrial, and automotive applications.
