EN11-HSM1AF15
Overview
The EN11-HSM1AF15 is a compact 11mm mechanical incremental rotary encoder designed for panel mounting and PCB integration. It provides a 2-bit gray code quadrature output with 20 pulses per revolution and includes an integrated push-on switch for user interface navigation. The vertical orientation and threaded M7 bushing make it a reliable choice for human-machine interface (HMI) controls in space-constrained designs.
Why Choose This Part
This encoder features a robust metal bushing and flatted shaft for durability, rated for 30,000 rotational cycles. The combination of 20 detents and a built-in momentary switch allows for both incremental adjustment and selection in a single compact footprint.
Applications
Key Specifications
Getting Started
To integrate this encoder, connect the A and B quadrature pins to microcontroller GPIOs with internal pull-up resistors or external 10k ohm resistors. Use interrupt-driven logic or periodic polling to decode the gray code state transitions, and ensure a hardware RC filter or software debouncing routine is implemented to manage mechanical contact bounce.
