AUTONICS Equipment We Repair — By Category
AUTONICS Product Lines We Repair
Our engineers are trained on the full AUTONICS product range. Below are the major product families we service.
Photoelectric Sensors (BX, TL, SX, DX Series)
Autonics photoelectric sensors detect objects by light reflection and are widely used in Indian packaging, textile, and food processing lines. Common failures include lens contamination, LED drift, output failure, and threshold sensitivity loss in high-humidity or dusty environments.
Proximity Sensors (PR, PSN, PSEN Series)
Inductive and capacitive proximity sensors from Autonics enable touchless object detection in automotive and heavy machinery applications. Typical faults include coil short-circuits, sensitivity drift, connector corrosion, and false triggering in metallic environments common to Indian CNC and assembly lines.
Temperature and Humidity Controllers (TZN, THD Series)
Autonics thermal controllers regulate process temperatures in pharmaceutical, chemical, and textile dyeing plants across India. Repair issues include thermocouple faults, control loop instability, display panel malfunction, relay contact failure, and calibration drift over time.
PLC Modules (PLC-B, AP Series)
Autonics compact PLCs control logic-based automation in Indian small and medium manufacturing units. Common faults include CPU module failure, I/O card malfunction, memory corruption, communication port failure (RS232/RS485), and firmware corruption after power surges.
Stepper Motor Drivers (MD, SMD Series)
Autonics stepper drivers control precision positioning in textile machinery, printing equipment, and CNC routers across Indian workshops. Typical failures include gate driver IC burnout, heat sink thermal paste degradation, PWM circuit failure, and connector pin corrosion in shop-floor environments.
Counter and Timer Units (CT Series)
Autonics digital counters and preset timers manage production counting and dwell timing in high-speed Indian manufacturing lines. Common issues include display segment failure, counting relay fatigue, input sensitivity loss, and reset button mechanical wear affecting operational reliability.
Communication Modules (CAN, Modbus, Ethernet Adapters)
Autonics communication cards enable Industry 4.0 integration and networked sensor data transfer in modern Indian smart factories. Faults include connector corrosion, protocol configuration loss, isolation circuit failure, and EMI-induced signal corruption in noisy factory environments.

Common AUTONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AUTONICS equipment arriving at our workshop.
- ✓Photoelectric sensor no output signal — Autonics photoelectric sensors fail to output when the lens gets contaminated by oil mist, dust, or moisture in Indian textile and food plants. Internal LED may also degrade, or the output relay contacts become stuck open due to electrical stress.
- ✓Proximity sensor sensitivity loss or false triggering — Autonics inductive proximity sensors lose accuracy when coil windings degrade, or when placed near high-frequency electrical noise common in Indian CNC and welding shops. Capacitive types fail when exposed to moisture ingress or conductive dust accumulation.
- ✓Temperature controller display blank or erratic readings — Autonics TZN and THD series controllers develop display failures when LCD segments degrade, or when the thermocouple connector loosens due to vibration in Indian pharmaceutical and textile dyeing environments. Main PCB solder joints also crack from thermal cycling.
- ✓PLC CPU module not responding or communication lost — Autonics PLC-B and AP series modules fail when power supply fluctuations cause CPU brownout, or when RS232/RS485 connectors corrode in humid Indian factory conditions. Firmware corruption can occur after unplanned power cuts or static discharge during maintenance.
- ✓Stepper motor driver not energizing or stalling — Autonics stepper drivers (MD, SMD series) fail when gate driver ICs overheat due to poor thermal contact, or when the PWM circuit receives corrupted step/direction signals from Indian CNC controllers. Electrolytic capacitors also dry out in high-temperature shop environments.
- ✓Counter unit display malfunction or counting errors — Autonics counter and timer modules develop display segment failure when LCD driver IC degrades, or when the counting input relay gets stuck due to mechanical wear in high-speed Indian production lines. Power transients can also corrupt counter memory settings.

Frequently Asked Questions — AUTONICS Repairs
Do you repair Autonics equipment anywhere in India?+
Yes. Synchronics repairs the full Autonics product range — photoelectric and proximity sensors, temperature controllers, PLC modules, stepper drivers, counters, and communication adapters. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other major industrial cities. All repairs are performed at our certified facility in Vadodara, Gujarat, with 48-72 hour standard turnaround.
What is the most common Autonics sensor repair issue in Indian factories?+
Photoelectric sensor failure due to lens contamination is the most frequent issue we see across Indian textile, food, and packaging plants. Oil mist, dust, and moisture accumulate on the lens, reducing optical transmission. Synchronics provides professional lens cleaning, LED/phototransistor testing, and calibration. We also recommend preventive maintenance schedules and suggest protective covers for high-contamination environments.
Can Synchronics repair Autonics PLC firmware corruption or communication loss?+
Absolutely. Firmware corruption in Autonics PLC-B and AP series modules is common after power surges or unplanned shutdowns. Synchronics uses original Autonics firmware and specialized programming tools to restore CPU modules. We also diagnose and repair RS232/RS485 communication port failures, test all I/O channels, and verify networked operation before returning the PLC.
How long does Autonics sensor or controller repair typically take?+
Standard Autonics repairs — sensor cleaning, controller calibration, relay replacement, or display repair — take 24-48 hours at Synchronics. Complex cases like PLC firmware restoration or stepper driver coil rewinding may require 3-5 days. We offer express turnaround for critical production equipment. Call us at our Vadodara facility to confirm timelines for your specific Autonics equipment.
Do you provide Autonics spare parts or only repair service?+
Synchronics primarily offers repair and restoration of Autonics equipment. For routine spare parts (sensors, relays, connectors, displays), we recommend contacting authorized Autonics distributors in your region. However, if you have failed Autonics modules we cannot economically repair, we can help identify compatible replacement units or guide you to certified Indian distributors stocking Autonics inventory.
How do I send my AUTONICS 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 AUTONICS 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 AUTONICS 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 AUTONICS 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.
