Selection Guide
Use the HC20 series part number structure to select the correct variant:
- HC20 – Series identifier (58 mm incremental encoder)
- 2500 – Resolution: 2500 PPR
- 0 – Shaft type: 0 = solid shaft 6 mm
- XX – Flange/mounting code (application-specific)
- 0 – Cable exit direction
- A – Output circuit: A = push-pull 5–24 V
- J – Connector type: J = M12 connector
- 2 – Cable length / termination code
Need a different PPR (100, 360, 500, 1000, 5000) or output type (RS422, HTL, TTL)? Contact Konmask.com for the correct part number.

Replacement & Compatibility FAQ
Q: Can I replace the HC202500/0XX0AJ2 with an Omron E6B2-CWZ6C 2500P/R?
A: In many cases yes — both are 2500 PPR with 5–24 V supply. However, the Omron uses NPN open-collector output vs. push-pull on the Hengstler. Verify your controller’s input circuit before substituting.
Q: Is the HC202500/0XX0AJ2 compatible with Siemens SINAMICS drives?
A: Yes. With appropriate HTL/TTL input modules (e.g., SMC20, SME20), this encoder integrates directly with SINAMICS S120 and G120 drives.
Q: What does the suffix 0XX0AJ2 mean?
A: The suffix encodes shaft type, flange, cable exit, output circuit (A = push-pull), connector (J = M12), and termination. See the Selection Guide section above for a full breakdown.
Q: Do you supply original Hengstler or compatible replacements?
A: We supply both. All units are clearly labeled as OEM original or compatible equivalent. Contact us to specify your preference.
Q: What is the minimum order quantity?
A: MOQ is 1 piece. Volume discounts apply for orders of 5+ units.
