If you're shopping for sensors and encoders for machine safety, the main question is whether you need a full measuring system or a single component. One package comes with everything for roll length measuring; the other is a small part for DIY controls. The price difference between them reflects that: one is a ready-to-run system, the other is a part to build into something you already have.
Quick Verdict
Pick the complete kit if you want a ready-to-run measuring system with a direct readout. Pick the EC11 if you're replacing or building a DIY project and need a compact encoder. The right choice comes down to whether you want a complete system or a build-it-yourself component.
Comparison at a Glance
| Product | Price | What's included | Best for |
|---|---|---|---|
| Digital Meter Counter with Wheel & Mounting Bracket | USD 86.20 | Digital meter counter, encoder, wheel, mounting bracket | Roll length measurement and equipment control |
| EC11 30-Position Rotary Encoder | USD 21.00 | Single encoder with integrated switch | DIY project replacement |
Where Each Product Wins
The complete kit wins if your project involves measuring material length, counting rotations, or using a relay output to stop or start equipment. With the meter and encoder in one package, you can set up a measuring station without tracking down parts individually.
The EC11 wins if you need a compact part for a DIY project. It is a single component, so you'll integrate it into your own circuit. That gives you flexibility in the final build.
Product Notes
300ppr Rotary Encoder Digital Meter Counter with Wheel & Mounting Bracket
This is the all-in-one choice for roll length measuring. The package is complete, so you don't need to track down extra parts. The encoder sends 300 pulses per wheel revolution, and the controller has a relay output that can stop or start connected equipment. It works on 110-220V with a US plug, making it easy to power in a workshop. You can also set an early warning value to know when you're close to the target. The trade-off is that this is a larger wired system, not a compact knob, so you need space for the meter and support hardware. At USD 86.20, it's the higher-priced option, but it's a complete system rather than a single part.
One 5PIN EC11 30 Position Rotary Encoder With Push Switch Split Shaft
This is the practical component for DIY projects. It has detented positions and an integrated switch, so you can rotate to select a value and press to confirm it. The split shaft fits into a knob, and the 5-pin layout is straightforward for wiring into a radio. Because it's a compact part, it can fit into tight spaces without adding bulk. At USD 21.00, it's the more affordable option, but it is a single component rather than a full kit, so your project will need the rest of the control setup already planned. Choose a knob that matches the 12.5mm shaft, and integrate the encoder into your circuit. If your project needs a compact rotary encoder with a click action, this part fits that role well.
Final Choice by Use Case
For a workshop measuring project where you want to track roll length and control equipment, the complete kit is the clear choice. For a radio repair or DIY project where you need a compact encoder, the EC11 is the right fit. Think about whether you want a complete readout system on your bench or a small component inside a radio. Let the completed system versus the single component decide for you.
