AUTONIC Product Lines We Repair
Our engineers are trained on the full AUTONIC product range. Below are the major product families we service.
Photoelectric Sensors (E3X Series)
AUTONIC's E3X photoelectric sensors detect object presence, color discrimination, and distance measurement in conveyor systems, packaging lines, and assembly automation. Common faults include lens contamination, amplifier drift, and output relay failure in high-humidity Indian manufacturing environments.
Proximity Sensors (PR Series)
AUTONIC PR-series inductive and capacitive proximity sensors operate in harsh industrial conditions including metal stamping, injection molding, and heavy machinery assembly. Typical repair needs involve oscillator circuit failures, sensitivity drift, and connector corrosion in dusty foundry and mill environments.
Control Relays and Timer Modules (ATM Series)
AUTONIC ATM series digital timers, counters, and relay modules provide logic sequencing in textile mills, sugar plants, and steel mills. Failures typically stem from contact oxidation, microprocessor faults under thermal stress, and input signal noise in electromagnetic-heavy environments across Indian industrial zones.
Fiber Optic Sensors (E2FQ Series)
AUTONIC E2FQ fiber optic sensors deliver non-contact detection for high-temperature, explosive, and electrically noisy applications in steel mills, foundries, and petrochemical refineries. Repair involves fiber alignment checks, light source replacement, and receiver amplifier diagnostics.
Safety Light Curtains (BM3 Series)
AUTONIC BM3 safety-rated light curtains protect machine operators in press shops, textile looms, and automotive assembly lines across India. Repair addresses misalignment issues, receiver sensitivity loss, and safety relay circuit faults that compromise workplace safety compliance.
Temperature and Pressure Transmitters (TX Series)
AUTONIC TX-series analog transmitters convert sensor inputs to 4-20mA or voltage signals for PLC integration in process industries. Common issues include zero/span drift, output noise, and connector degradation in humid paper mills, chemical plants, and dairy facilities.

Common AUTONIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AUTONIC equipment arriving at our workshop.
- ✓E3X photoelectric sensor output relay stuck closed — Contaminated relay contacts and aged internal switching circuitry in AUTONIC E3X amplifiers exposed to high ambient dust in Indian textile and flour mills. Thermal cycling across seasons weakens contact pressure.
- ✓PR proximity sensor losing sensitivity or false triggering — AUTONIC PR inductive sensors experience coil degradation when mounted near high-current welding equipment or subject to vibration from heavy stamping presses. Capacitive models fail due to accumulated moisture and salt spray in coastal Indian facilities.
- ✓ATM timer module displays flashing error code or no output pulse — AUTONIC ATM microprocessor corruption from power surges, inadequate input signal conditioning, or crystal oscillator failure in dusty Indian mills with poor electrical infrastructure. Thermal cycling causes solder joint cracks on printed circuit boards.
- ✓E2FQ fiber optic sensor no light signal to receiver — AUTONIC fiber tip fracture from mechanical handling, oil contamination on fiber end face, or light source LED failure in heat-intensive foundries and steel mills where thermal stress degrades optical coupling. Dust ingress onto ferrule causes intermittent signal loss.
- ✓BM3 safety light curtain beam misalignment or receiver sensitivity loss — AUTONIC BM3 optical alignment shifts due to machine vibration, thermal expansion of mounting brackets in Indian automotive and heavy equipment factories. Receiver photodiode aging or dust accumulation on lens reduces light collection efficiency.
- ✓TX transmitter output drifts or becomes nonlinear — AUTONIC TX conditioning amplifier component aging, reference voltage regulator failure, or input connector oxidation in high-humidity environments like sugar plants, dairies, and chemical processing facilities across India. Thermal shock causes calibration drift.

Frequently Asked Questions — AUTONIC Repairs
Do you repair AUTONIC equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete AUTONIC product range — photoelectric sensors, proximity sensors, safety light curtains, timers, counters, and transmitters. We provide door-to-door pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all major Indian cities. Repairs are completed in our ISO-certified facility in Vadodara, Gujarat with 48-72 hour turnaround for most faults.
What is AUTONIC E3X sensor lens contamination and how do you fix it?+
AUTONIC E3X photoelectric sensors rely on precise lens optics to detect objects. In dusty Indian textile mills, flour plants, and packaging facilities, oil vapor and dust accumulate on the lens, causing the sensor to fail detection or trigger falsely. Synchronics disassembles the E3X head, cleans all optical surfaces with precision-grade solvents, recalibrates sensor gain, and tests detection range before return. We also recommend periodic maintenance intervals based on your facility environment.
Can you repair AUTONIC PR proximity sensor coil faults?+
Yes. AUTONIC PR inductive sensor coil failures occur when welding equipment, induction heaters, or power cables run too close to sensor wiring in automotive and manufacturing plants. Our engineers perform coil continuity testing, replace corroded windings, and re-pot the sensor head. We also provide shielded cable recommendations and proper grounding techniques to prevent future coil degradation in your specific application.
How do you handle AUTONIC BM3 safety light curtain alignment issues?+
AUTONIC BM3 safety curtains protect press machine operators and assembly line personnel. Misalignment caused by vibration or thermal expansion of mounting brackets is a common issue in Indian automotive shops. Synchronics uses precision laser alignment tools to verify beam geometry, replaces worn photodiode elements, and cleans optical surfaces. We perform full safety certification testing per IEC 61496 standards and provide mechanical shims to lock alignment against future vibration.
What warranty and support does Synchronics offer on AUTONIC repairs?+
All AUTONIC repairs carry a 12-month warranty on repaired components and all replaced parts. We provide technical support throughout the warranty period and offer preventive maintenance schedules tailored to your industry — textile mills typically need quarterly checks, while foundries and steel mills may require monthly verification. Our engineers are available for phone support and on-site consultation across India.
How do I send my AUTONIC 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 AUTONIC 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 AUTONIC 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 AUTONIC 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.
