The Movomatic C25 3000980 is a high‑precision electronic touch trigger probe used in CNC machining and grinding operations to detect tool contact and provide real‑time feedback to the controller. Common failure modes in this class of probes include degraded signal integrity due to cable wear or connector corrosion, power supply ripple affecting the internal microcontroller, and sensor drift caused by temperature cycling or mechanical shock. For initial troubleshooting, verify that the probe receives its rated 12 V DC input within ±5 %, inspect all wiring harnesses for signs of abrasion or broken insulation, and confirm that the probe’s output signals (typically a 0–10 V analog or TTL digital pulse) match the controller’s expected levels. If the probe is connected to a PLC or CNC system, review any error logs or diagnostic codes that reference “touch probe failure” or “contact loss.”[oss-gpt-20b]
