Hohner HNE-322C-7-LX-SU (P/N 20013660) — 22mm Clamp-Flange Hollow-Shaft Encoder, Push-Pull, Single-Turn

Hohner Encoder · HNE-322C Series · Incremental · 7mm Hollow Shaft · In Stock

The Hohner HNE-322C-7-LX-SU (Hohner internal part number 20013660) is a compact incremental rotary encoder in a 22mm clamp-flange housing with a 7mm through hollow shaft. The “LX” suffix denotes push-pull (line-driver) output stages, while “SU” marks the single-turn mechanical configuration. It is engineered for small-format positioning and speed feedback on stepper, closed-loop stepper, and low-power servo axes used in factory automation, packaging, printing registration, conveyor systems, and laboratory / medical equipment. Hohner Elektrotechnik is a long-established German encoder brand and a sister company of Hengstler within the Hengstler Group, with field-proven designs in continuous duty on European and Asian production lines.

Sourced through KOEED’s China sourcing network with full traceability, the HNE-322C-7-LX-SU ships worldwide via DHL or FedEx with a 90-day warranty. For multi-line BOM quotes, see our Hohner HNE-322C family listing or send the full instruments list to Moritta@KOEED.COM.

1. Key Technical Specifications & Overview

2. Application Scenarios — Where It Fits

The Hohner HNE-322C-7-LX-SU is sized for small-shaft machinery where panel real estate and wiring complexity must stay minimal. The 7mm through-bore slips directly onto the driven shaft, removing the need for a coupling or an additional mounting bracket. Typical placements include:

• Closed-loop stepper feedback on NEMA 17 / NEMA 23 axes where the 7mm hollow bore matches common motor shaft diameters (with sleeve adapter where required).
• Small AC servo feedback for laboratory automation, dispensing heads, and pick-and-place gantries.
• Conveyor speed measurement on packaging lines that already use Allen-Bradley Micro800 high-speed counters or Siemens SIMATIC ET200S counter modules.
• Packaging and labelling registration, paired with Mitsubishi MELSEC-Q or Omron SYSMAC CJ2 motion modules.
• Printing registration marks in label printers and inline marking systems, where the index pulse (Z) drives the print-trigger latch.
• Medical and laboratory analyzers requiring IP65 sealing and a low-profile 22mm flange footprint.
• Robotics and CNC auxiliary axes on platforms built around Fanuc, Schneider Lexium, Yaskawa Σ-7, Panasonic MINAS, or KEYENCE vision-guided cells.

3. Integration & Wiring Notes

The LX push-pull output stage provides six lines — A, A¬, B, B¬, Z, Z¬ — on a 5–30V DC supply. Differential signalling is recommended for cable runs beyond two metres to reject common-mode noise from VFD-bearing cabinets. Wire colour conventions follow Hohner’s standard; always cross-check against the label affixed to the 20013660 unit before energising.

Compatible counter / motion interfaces include:

• Allen-Bradley Micro800 2080-MOTION high-speed counter modules.
• Siemens SIMATIC ET200S 6ES7 counter modules and S7-1200 HSC inputs.
• Beckhoff EL5xxx incremental encoder terminals (via KOEED’s encoder product index).
• Mitsubishi QD62 / QD62E high-speed counter units and Omron CJ2M-CT021 pulse I/O modules.

For cable pin-out specifics on the 20013660 lot, request the Hohner datasheet via Moritta@KOEED.COM — include the host PLC platform so we can pre-validate the pin map against your counter module.

4. Installation & Commissioning Tips

• Shaft alignment. Slip the 7mm hollow bore directly over the driven shaft; a soft sleeve compensates for nominal bore mismatch (e.g. 6mm motor shafts).
• Clamp torque. Tighten the 22mm clamp-flange screw to Hohner’s specified torque (typically 2–3 Nm) to avoid slip yet protect the housing.
• Anti-rotation arm. Engage the anti-rotation slot or torque arm on the encoder body; do not rely solely on the clamp friction.
• Bend radius. Maintain the manufacturer-specified cable bend radius (typically ≥ 10x OD) and route signal cable away from VFD power runs to keep noise immunity intact.
• Sealing check. Inspect the shaft seal for damage before mounting; the IP65 rating is contingent on a clean, undamaged seal.
• First-power verification. Before loading the machine, jog the axis slowly and confirm A/B phase relationship plus Z index pulse at the counter module’s diagnostic page.
• Troubleshooting shortcuts. Use KOEED’s PLC Error Code Database or the AI Diagnostic Tool to decode counter-module faults tied to encoder wiring.
