Choosing between a single EC11 rotary encoder and the Precision 360° encoder pack comes down to how many control knobs you need and how you want to wire them. Both products use a shaft actuator and through-hole mounting, so they fit similar board-level builds in sensors, encoders, and machine-safety work. The EC11 is a one-piece encoder with a push-to-actuate switch; the Precision pack is aimed at stepper and servo control.
Quick verdict
For a single dial with click-to-select, the EC11 360 Degree Rotary Encoder is the focused choice at USD 2.50. If you need multiple 360° controls that count in both directions and drive motors, the Precision 360° Rotary Encoder Pack is the more complete choice at USD 12.99.
| Product | Listed Price | Price Bar | Key Facts |
|---|---|---|---|
| 1 Pc - EC11 360 Degree Rotary Encoder PCB Mount Push Switch D Shaft | USD 2.50 | Single encoder with D shaft and 20 pulses per revolution | |
| Precision 360° Rotary Encoder Pack of 4 - Ideal for Stepper and Servo Motors | USD 12.99 | Four-module set with knob caps, 5V, 20 pulses per rotation, forward/reverse counting |
Where each product wins
The EC11 gives you a single, targeted encoder for one manual input. If you need exactly one control, that is the simpler route. The Precision pack provides multiple modules, directional pulse counting, and a module-style layout. If your project needs several encoder inputs, the pack covers more at once.
1 Pc - EC11 360 Degree Rotary Encoder PCB Mount Push Switch D Shaft
The EC11 360 Degree Rotary Encoder is a conventional through-hole rotary control with a D shaft and a push-to-actuate momentary switch. It produces 20 pulses per revolution in each direction, has switch contacts rated for 5 V at 10 mA, and uses a 7-pin PCB-mount layout. That makes it a straightforward choice for a single manual input where you also want a click action from the same component. The clear limitation is the package: you get one piece, so if your control panel needs three or four shafts, you have to source additional units. For a one-knob build, though, it keeps the BOM short.
Precision 360° Rotary Encoder Pack of 4 - Ideal for Stepper and Servo Motors
The Precision 360° Rotary Encoder Pack of 4 includes modules with knob caps. It counts output pulses during both forward and reverse rotation, supports unlimited rotations, and runs from a 5 V supply. The intended roles include stepper and servo motor control plus digital potentiometer applications. That makes the pack useful when you need multiple encoders on one board or test fixture. The trade-off is the multi-module package: a single-dial project may not use every included module. It is also a module-style part, so mounting and wiring follow the module's pin layout rather than a bare PCB-pin encoder footprint.
Final choice by use case
Need exactly one rotary control on a PCB-mount footprint? Choose the EC11 360 Degree Rotary Encoder. Need several 360° encoder modules for a stepper or servo motor project? Go with the Precision 360° Rotary Encoder Pack of 4.
