Rotary encoders are a standard building block in sensors encoders and machine safety setups, but choosing one can feel like a guessing game when the listed prices run from $21 to $425. The main decision is whether you need a detented manual control with a push switch or a high-resolution incremental feedback encoder for a machine axis. These four new units cover both ends of that spectrum. On the low end is a 5-pin EC11 split-shaft encoder with push switch; on the high end is a Heidenhain ERN 180 incremental encoder. In between are the Omron E6B2-CWZ6C at $68.90 and the Hontko HTR-HB-8-600-2-PP at $200.48.
Quick take
For a quick decision: the EC11 is the $21 entry point with a push switch and split shaft for manual controls. The Omron E6B2-CWZ6C adds a stated 500 P/R and a 5-24 VDC range for $68.90. The Hontko HTR-HB-8-600-2-PP sits at $200.48 as a new-in-box rotary encoder, and the $425 Heidenhain 589614-1X is the highest-priced incremental unit in this lineup. Pick the EC11 for simple knobs, the Omron for speed feedback, and the Heidenhain for a high-resolution axis. The Hontko fits when you need that exact HTR-HB-8-600-2-PP replacement.

Decision matrix
Use the model number and the listed electrical details as your first filter.
- Need a knob with push-to-select? The EC11 has 30 positions and a split shaft.
- Need an encoder with a named resolution and supply range? The Omron states 500 P/R and 5-24 VDC.
- Need a new-in-box encoder from the Hontko HTR-HB line? The $200.48 unit is the only one from that line here.
- Need the highest-priced incremental feedback option, with 3600 in the model? The Heidenhain is your pick.
Product notes
New Heidenhain 589614-1X Incremental Rotary Encoder ERN 180 3600 03S12-03 K Unit
The $425 price puts this Heidenhain unit at the very top of the comparison. The listing describes it as brand new and unused in box, with incremental encoding and a country of origin of Germany. The ERN 180 3600 designation appears in the title, and the 3600 is the main numeric feature to work with if you are comparing resolutions. The trade-off is cost: it is the most expensive item here by a wide margin. Choose it only if your machine calls for this specific ERN 180 form factor and that higher count matters. For simpler tasks, the Omron or EC11 will cost considerably less.
New In Box HONTKO HTR-HB-8-600-2-PP Rotary Encoder
At $200.48, this Hontko is the second-highest-priced unit in the group. Its listing confirms the new-in-box condition and leaves the model number to carry the identification weight. That makes it a candidate for someone who already has a HTR-HB-8-600-2-PP and needs the same unit for a replacement or a spare. The limitation is the gap between the mid-range price and the level of documented specification. Compared with the Omron, which states 500 P/R and 5-24 VDC, and the Heidenhain, which names the ERN 180 3600 series, the Hontko supplies less information about resolution and electrical interface at nearly three times the Omron's price.
New OMRON E6B2-CWZ6C Rotary Encoder 500P/R 5-24VDC
The Omron E6B2-CWZ6C at $68.90 is the mid-priced option with the clearest stated electrical specs: 500 P/R and a 5-24 VDC supply range. It is listed as new in box, so you get a fresh part for $68.90 compared with $425 for the Heidenhain. The 500 P/R resolution is a moderate count for feedback applications, useful for motor speed monitoring and position control without the cost jump of the $425 unit. The limitation is that 500 P/R is a lower count than the 3600 figure associated with the Heidenhain. If your closed-loop axis needs a much higher pulse-per-revolution rate, the Omron will not get you there.
One 5PIN EC11 30 Position Rotary Encoder With Push Switch Split Shaft
The EC11 30 Position rotary encoder with push switch and split shaft is the low-priced entry at $21. It is a 5-pin unit with a 12.5 mm shaft length stated in the description, and the integrated push switch makes it useful for encoder-plus-button interfaces. The listing gives the country of origin as China. The limitation is that this is a manual-control, switch-style part, not a high-resolution feedback encoder. If your goal is a detented knob for a radio or panel, the price is the lowest in this comparison. If you need closed-loop speed feedback, the Omron or Heidenhain are more appropriate.
Final recommendation by use case
For a manual selector knob with push-to-select functionality, start with the EC11 30 Position with push switch. For general-purpose incremental feedback with 500 P/R and 5-24 VDC, the Omron E6B2-CWZ6C is the natural match. If you need an exact Hontko HTR-HB-8-600-2-PP replacement, choose that model and accept its higher listed price. For a feedback encoder with a 3600 in the model and a Germany origin, the Heidenhain 589614-1X is the top-priced option. The right choice comes down to whether the encoder is a finger-operated knob or part of a motion feedback loop.
