Choosing between two rotary encoders feels like a no-brainer until you look at what each is built for. One is an EC11 360-degree rotary encoder; the other is a unit for the KOYO TRD-N1000-RZ. Your real decision isn't just price; it's whether you need a general-purpose board-level encoder or a specific named model.
For most control-panel and knob-style projects, the EC11 is the more practical buy because it comes with concrete specs. If you are working with equipment that calls for a KOYO TRD-N1000-RZ, the unit for that model is the one to consider. The EC11 is not a named replacement; it is a component you integrate. The KOYO unit is defined by a model reference. Use the table below to anchor the price.
| Product | Price | Price Bar | Best for |
| 1 Pc - EC11 360 Degree Rotary Encoder PCB Mount Push Switch D Shaft | USD 2.50 | | Board-level projects needing a rotary encoder |
| For KOYO TRD-N1000-RZ Rotary Encoder | USD 63.84 | | Anyone seeking a unit for the KOYO TRD-N1000-RZ |
Where each product wins
EC11 wins for price and detail. At $2.50, you get a single EC11 with D shaft, 7-pin PCB mount, 15 mm shaft length, PC-pin termination, and push-to-actuate momentary switch. It also provides 20 pulses per revolution and 5 V / 10 mA switch contacts.
KOYO model unit wins for model specificity. It is new and for the KOYO TRD-N1000-RZ rotary encoder. If your project or machine references that exact encoder, this product answers that need directly, albeit at $63.84.
1 Pc - EC11 360 Degree Rotary Encoder PCB Mount Push Switch D Shaft

This EC11 is the component-level option in this pairing. It is a single 360-degree rotary encoder with a D shaft, through-hole PCB mounting, and a push-to-actuate momentary switch. It uses PC-pin termination, and the mechanical switch contacts are rated at 5 V / 10 mA. It comes as one piece, so you are buying a single EC11, not a pack. If you're building a control panel or another knob-style project and need a board-mounted encoder, the specs give you a clear starting point: 15 mm shaft length, 7 pins, and 20 pulses per revolution. The main thing to weigh is whether you need a board-level component or a specific model match. This is a bare PCB-mount encoder with a fixed 15 mm shaft, so confirm that length against your knob or panel. For many projects, the combination of technical detail and component-level design makes it worth considering.
For KOYO TRD-N1000-RZ Rotary Encoder

This option is the model-specific pick in this head-to-head. It is a new unit for the KOYO TRD-N1000-RZ rotary encoder. If your equipment references that specific model, this product gives you a direct match rather than trying to adapt a general-purpose EC11. Choosing this unit only makes sense when the model number is already in your equipment's spec. It does not try to be a general rotary encoder; it is a product for a specific KOYO reference. The decision comes down to whether the KOYO TRD-N1000-RZ name is part of your equipment's requirement. With its new condition and model-specific title, it is the straightforward choice for that scenario. If you are not tied to that model, the EC11 remains the more general route.
Final choice by use case
- For a project that fits the EC11's specs, pick the EC11.
- For a KOYO TRD-N1000-RZ application, pick the unit for KOYO.
Your final pick should be based on whether you are assembling a board or tracking down a specific encoder model.
