AUTONIX Product Lines We Repair
Our engineers are trained on the full AUTONIX product range. Below are the major product families we service.
Inductive Proximity Sensors
Autonix inductive proximity switches detect ferrous and non-ferrous metal objects without physical contact. Common failures include coil burnout due to voltage surge, oscillator circuit failure, and connector pin corrosion in wet industrial environments causing intermittent signal loss.
Photoelectric Sensors
Autonix photoelectric sensors operate across visible and infrared spectrums for object detection, color detection, and distance measurement. Repair challenges include LED degradation, photodiode sensitivity loss, ambient light interference calibration errors, and analog output drift over extended operation periods.
Capacitive Sensors
Capacitive proximity sensors detect metallic and non-metallic materials including plastics, glass, and liquids. Common faults involve sensitivity calibration drift, false triggering due to environmental humidity changes, and PCB component aging causing unreliable detection thresholds.
Limit Switches and Lever Arms
Rugged mechanical limit switches used for position sensing and emergency stop circuits in packaging and material handling equipment. Failures stem from mechanical wear of actuator arms, switch contact pitting from electrical arcing, and connector corrosion in dusty manufacturing floors.
Analog Output Modules and Signal Conditioners
Autonix signal conditioning modules convert sensor outputs to standard 4-20mA or 0-10V signals for PLC integration. Repairs address D/A conversion errors, amplifier offset drift, impedance matching failures, and noise filtering degradation in electrically noisy plant environments.
Connector and Harness Assemblies
Autonix M12 and M8 connector systems provide rugged sealed connections for harsh environments. Common issues include pin contact oxidation, moisture ingress causing short circuits, mold degradation on connector seals, and intermittent connections from vibration-induced micro-movement.

Common AUTONIX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AUTONIX equipment arriving at our workshop.
- ✓Intermittent sensor signal loss on detection — Autonix proximity sensors experience intermittent dropout due to corroded M12 connector pins exposed to humidity and salt spray in coastal Indian manufacturing plants, or loose internal connections from vibration-induced wear. This causes unpredictable PLC input failures affecting production timing.
- ✓Photoelectric sensor detection range reduced — Autonix photoelectric sensors lose detection range due to LED output degradation over 3-5 years of continuous operation, optical window contamination from dust and oil mist, or photodiode sensitivity drift from thermal aging. Typical range loss reaches 40-60% before failure detection.
- ✓Capacitive sensor false triggering on humidity changes — Autonix capacitive sensors generate false triggers when ambient humidity fluctuates sharply in textile mills, paper factories, and pharmaceutical cleanrooms. The sensor's capacitive circuit becomes sensitive to environmental dielectric changes, particularly when mounting substrate absorbs moisture through PCB via holes.
- ✓4-20mA output signal drift beyond acceptable tolerance — Autonix analog signal conditioning modules develop output offset drift of 2-8% from amplifier IC aging, reference voltage regulator degradation, or precision resistor network drift in high-temperature environments common in steel mills and foundries. This creates measurement errors in upstream PLC loops.
- ✓Limit switch fails to reset after actuation — Autonix mechanical limit switches develop sticking contacts from electrical arcing damage to switch contacts in pneumatic automation circuits, or mechanical binding of the actuator arm from corrosion and mineral deposits. Spring tension may also degrade allowing contacts to remain closed.
- ✓Connector water ingress causing short circuit failure — Autonix M12 sealed connectors fail in high-pressure washdown environments on production lines due to micro-cracks in connector mold, worn sealing O-rings, or improper mating force during field reconnections. Moisture reaches PCB causing shorted components and sensor disable.

Frequently Asked Questions — AUTONIX Repairs
Do you repair Autonix equipment anywhere in India?+
Yes. Synchronics repairs the complete Autonix sensor and control device portfolio including proximity sensors, photoelectric units, capacitive switches, limit switches, and signal conditioning modules. We offer PAN India express door pickup from all major cities - Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and beyond. All repairs are performed in our advanced facility in Vadodara, Gujarat. Typical turnaround is 5-7 working days with full warranty coverage.
What is the typical turnaround time for Autonix sensor repair?+
Standard Autonix repair turnaround is 5-7 working days from receipt in our Vadodara facility. Sensor diagnostics, component replacement, and calibration are completed in parallel. Express 2-3 day repairs are available for critical production line sensors with premium charges. We provide real-time repair status updates and can coordinate immediate return shipment on completion.
Can you repair Autonix inductive sensors with intermittent signal loss?+
Absolutely. Intermittent sensor signals are one of our specialties with Autonix equipment. Common causes are corroded M12 connector pins, loose PCB solder joints from vibration, or coil winding micro-fractures. We perform ultrasonic cleaning of connectors, X-ray inspection of internal solder joints, and comprehensive electrical testing under simulated vibration conditions. Most intermittent signal sensors are fully restored to factory specifications.
Do you offer calibration certificates for repaired Autonix sensors?+
Yes. All Autonix sensor repairs include full calibration against traceable standards with detailed test certificates. Photoelectric sensors are tested for LED output, optical range, and linearity. Analog signal conditioners are calibrated for 4-20mA accuracy using NIST-traceable current sources. Proximity sensors undergo distance measurement verification. Certificates document all measurement data and pass/fail criteria per Autonix manufacturing specifications.
Which Autonix sensor models are most commonly repaired?+
The AKD series inductive proximity sensors (AKD3001, AKD4001, AKD5001) represent 35% of our Autonix workload due to high volume use in automotive plants. AKE photoelectric sensors are next most frequent (25%) particularly in pharmaceutical filling lines. Capacitive AKCE series sensors (20%) are common from food processing facilities. Signal conditioning modules and M12 connector failures complete the repair volume, especially from textile mills and foundries experiencing harsh environmental exposure.
How do I send my AUTONIX unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a AUTONIX drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on AUTONIX repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your AUTONIX unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
