Five small rotary encoders with D-shafts and five pins each

Unique-Bargains

Unique-Bargains EC12 360 Degree Rotary Encoder 5 Pin 14.3mm D-Shaft 5pcs

SKU CH-RMN2-6RD2A

Pack of five 360-degree rotary encoders with integrated push-switch, 24 detents, 5-pin D-shaft at 14.3 mm height and 5 V rating

  • 360-degree continuous rotation for precise control
  • 24 detents per revolution give tactile feedback
  • 5-pin layout simplifies breadboard wiring
  • 3 mm D-shaft fits standard knobs securely
  • 5 V logic level matches common microcontrollers

Rotary Encoder with Switch for Digital Control

The Unique-Bargains EC12 is a 360-degree rotary encoder that converts shaft motion into digital output signals. It suits hobbyists and engineers building control panels, robotics interfaces or custom input devices. The pack contains five units, each with a 14.3 mm D-shaft and five-pin layout. This component fits breadboard prototyping and permanent PCB designs alike.

Low-Power Operation at Five Volts

Rated for 5 V supply, the encoder draws minimal current and generates no audible noise during rotation. The mechanical switch clicks cleanly without electrical arcing under normal use. No active cooling is required and thermal output is negligible in typical low-voltage applications. The contacts are rated for reliable switching within the specified voltage range.

Compact Footprint for Tight Layouts

Each unit measures 14.5 mm by 12.7 mm by 21 mm overall, with a 6 mm shaft diameter and 12.5 mm shaft height. The D-shaft profile prevents knob slippage while allowing standard 6 mm bore caps. Five pins provide encoder A, B, common, switch normally-open and switch common connections. The small body frees board space for adjacent components in dense designs.

Questions about this item

How do I solder the 5 pins of this EC12 encoder to a PCB and which step causes misalignment?

Insert the 14.3 mm D-shaft through the panel, align the 5 pins with the PCB holes, and solder; the step that causes misalignment is forgetting to secure the 12.5 mm shaft height before the pins cool.

What maintenance will the encoder need after extended use?

Keep the unit away from high temperature, high humidity and corrosive gases; avoid any water contact because moisture can distort the output waveform.

At what point does the 24-digit resolution limit appear during continuous rotation?

The encoder outputs 24 distinct positions per 360 degree turn, so the resolution limit is reached each full rotation when the code repeats.
