EN11-HNM1BF25 is an 11 mm incremental rotary encoder from the EN11 Series featuring 2-bit gray code output and top-adjust configuration with a threaded metal bushing and shaft. The encoder provides 15 or 20 pulses per revolution with continuous mechanical travel and supports detent options of 0, 20, or 30 detents per revolution. Electrically, it operates at a maximum of 10 mA with a closed circuit resistance of 3 ohms maximum, contact rating of 10 mA at 5 Vdc, and dielectric strength of 300 Vac at 1 mA for 1 minute. Mechanically, the rotational torque of detent is 2.5 oz-in maximum, with a rotational life of 30,000 cycles. This encoder is ideal for applications requiring reliable position feedback in industrial controls, instrumentation, and consumer electronics where compact size and incremental sensing are essential.
