ASM SIPLACE 00343442 is the Y-axis incremental encoder / reading head used in legacy SIPLACE HS motion systems. Its strongest purchasing boundary is simple but important: 00343442 belongs to the Y axis, while the closely related 00343441 is the X-axis reference.
During a Y-axis feedback, positioning or servo-related investigation, the reading head is one part of the motion-feedback chain that may need inspection together with its connector, cable path and associated axis hardware. An axis alarm should not automatically be treated as proof that the encoder itself has failed.
00343442 Y-Axis Encoder Identification
| Part Number | 00343442; commonly documented as 00343442-05 / 00343442S05 |
|---|---|
| Part Type | Y-axis incremental encoder / reading head |
| Term Note | The reading head senses motion-position information used by the Y-axis feedback system |
| Machine Context | Legacy SIPLACE HS motion systems |
| Paired X-Axis Reference | 00343441 |
| Main Inventory Risk | X- and Y-axis reading heads being stored under one generic encoder description |
| Suffix Caution | Confirm the complete suffix from the removed unit before assuming another 00343442 version is interchangeable |
| Core Matching Point | Full P/N, suffix, Y-axis position, machine configuration, label and connector arrangement |
In a machine-down situation, issuing the X-axis 00343441 from stores for a Y-axis repair does not resolve the intended feedback requirement. The production impact is therefore not merely a wrong spare on the purchase order: the machine remains unavailable while maintenance reopens the job and waits for the Y-axis part.
For legacy HS fleets, the useful preventive step is inventory discipline. Mark 00343441 as X-axis and 00343442 as Y-axis directly in the spare-parts system and physical storage location, rather than depending on the generic description reading head.
