Unique-Bargains EC11 Rotary Encoder 20 Pulses 14mm Shaft 10pcs

SKU CH-3356-QZ6AP

Pack of ten 14 mm shaft rotary encoders with 20 pulses and integrated switch for 5 V digital control

  • 360-degree continuous rotation for unlimited adjustment
  • 20 pulses per revolution gives precise digital feedback
  • Five-pin layout with three signal pins simplifies wiring
  • 14 mm shaft height fits standard panel cut-outs
  • 5 V rated voltage matches common logic levels

EC11 Encoder Pack for Digital Control

This pack contains ten EC11 rotary encoders with integrated push switches. Each unit converts 360-degree shaft rotation into 20 digital pulses per revolution. They operate at a rated 5 Volt supply and feature a 14mm shaft height with a 6.7mm thread diameter. The 5-pin footprint includes three signal pins and two mounting pins for PCB stability.

Suited for Breadboard Prototyping and Panel Mounting

Makers building custom interfaces, volume knobs or menu navigation controls will find the 20-pulse resolution adequate for incremental adjustments. The 15mm by 12mm body fits standard perfboard spacing. Engineers needing absolute position data, higher pulse counts per turn or sealed industrial ratings should look at alternative sensor types not covered by this listing.

Ten Units Provide Spares for Iterative Builds

The 20 pulses per revolution give clear detent feedback for menu scrolling or parameter tuning in microcontroller projects. Mechanical life is limited by the unsealed construction, so dusty or high-vibration environments will degrade contact reliability faster than bench use. Each encoder measures 31mm total height, so ensure panel cutouts accommodate the 14mm shaft protrusion.

Questions about this item

What voltage supply do I need to power the EC11 encoder?

The encoder is rated for a 5 Volt supply, so provide a stable 5 V source for correct operation.

Will the 14 mm shaft fit into my existing 6.7 mm panel cutout?

The thread diameter is 6.7 mm, matching a standard 6.7 mm mounting hole, while the shaft itself extends 14 mm above the bushing.

How can I verify the encoder outputs the correct 20 pulses per revolution?

Rotate the shaft through 360 degrees and count 20 distinct signal transitions on each of the three working signal pins.
