Choosing between two rotary encoders in the sensors, encoders, and machine-safety space usually comes down to project scope: do you need a handful of general-purpose modules for building, or one unit aimed at a specific model? The Precision 360° Rotary Encoder Pack of 4 costs $12.99, while the For KOYO TRD-N1000-RZ Rotary Encoder costs $63.84. That is a $50.85 spread between the two, and it mirrors the difference between a four-module kit and a single targeted component.
Quick verdict
If you are working with stepper and servo motors, a 5V rotary encoder with 20 pulses per rotation is useful, and the four-pack gives you four modules for $12.99. Both units are listed as new. If you have a KOYO TRD-N1000-RZ in mind and want a new single encoder, the $63.84 unit is the more focused path.
At a glance
| Product | Listed Price | What Stands Out | Price Bar |

| Precision 360° Rotary Encoder Pack of 4 | $12.99 | Four KY-040 modules, 5V working voltage, 20 pulses per rotation, shaft actuator | |
| For KOYO TRD-N1000-RZ Rotary Encoder | $63.84 | Single unit for KOYO TRD-N1000-RZ-model applications |
Where each product wins
Precision 360° Rotary Encoder Pack of 4
- Gives you four modules in one $12.99 order.
- Runs at 5V and outputs 20 pulses per rotation.
- Counts pulses in both rotation directions and allows unlimited rotation, making it useful for stepper and servo motor control, digital potentiometer setups, and other rotary-input work.
- Listed with a shaft actuator and through-hole mounting.
For KOYO TRD-N1000-RZ Rotary Encoder
- Narrows the focus to one specific encoder model name.
- Is a single new unit, so there are no extra modules to store.
- Costs $63.84, which makes it the higher-priced item in this head-to-head.
Product notes
Precision 360° Rotary Encoder Pack of 4
This is the right pick when you want a 5V rotary encoder with 20 pulses per rotation and need more than one module on hand. The four KY-040 modules come with knob caps for hand turning, and the design supports pulse counting in both directions and unlimited rotation. That makes the set a good fit for stepper and servo motor work, digital potentiometer-style controls, and other projects where a rotary input is central. The limitation is the quantity: at $12.99 you are buying four modules, so if your build only calls for one, the extras may be more than you need.
For KOYO TRD-N1000-RZ Rotary Encoder
This purchase is focused on the KOYO TRD-N1000-RZ name in its title and costs $63.84 for one unit. If your application is built around that model, this is the more targeted single-encoder choice. It is listed as new, so the condition matches the four-pack in this comparison. The trade-off is the concentration: you are paying more for one encoder instead of four modules. For general-purpose projects, the Precision 360° pack is the lower-priced route; for a specific KOYO TRD-N1000-RZ setup, this unit points in the direction of the part you have in mind.
Final choice by use case
- Choose the Precision 360° Rotary Encoder Pack of 4 when you want four 5V modules for stepper and servo motor work at $12.99.
- Choose the For KOYO TRD-N1000-RZ Rotary Encoder when you have a KOYO TRD-N1000-RZ setup in mind and want one $63.84 unit aimed at that model.
