PEC11L-4120F-N0020 is an 11 mm low-profile rotary encoder from Bourns designed for compact audio-visual and consumer applications requiring precise rotational input control. The encoder features 2-bit quadrature output with 20 pulses per 360° continuous rotation, a metal flattened shaft, and an integrated push-momentary switch (SPST) with 100,000 actuations minimum life. It operates over a temperature range of -25°C to +80°C with an IP 40 rating, 100,000 rotational cycles minimum, and supports wave soldering at 260°C. The device delivers 0.5 mm switch travel with 610 ±306 gf actuation force and is ideal for level control, tuning, and timer settings in audio equipment, consumer appliances, environmental controls, and musical instrumentation.
