EC11E09244AQ is an 11mm size metal shaft rotary encoder featuring a vertical flat shaft configuration with two-phase incremental (A, B) output signal. The encoder operates at a rating of 10 mA 5V DC with a detent torque of 18 mN·m and 9 pulses per revolution, providing reliable position feedback for rotational control applications. It includes an integrated push-on switch with 1.5 mm travel distance and is rated for 15,000 operating cycles across a temperature range of -40°C to +85°C. This compact and highly reliable encoder is commonly used in consumer electronics, industrial control systems, and automotive applications where precise rotational sensing and user input switching are required.
