EDHARD Product Lines We Repair
Our engineers are trained on the full EDHARD product range. Below are the major product families we service.
EDHARD Proximity Sensor Range
Inductive and capacitive proximity sensors used in machine tool positioning, part detection, and conveyor systems. Common failures include coil burnout from electrical surges, oscillator circuit failure due to moisture ingress in humid factory floors, and connector pin corrosion in coastal Indian plants.
EDHARD Control Interface Modules
Signal conditioning and relay interface modules for PLC and motion control integration. Typical repair needs include relay contact welding under high-load switching, signal-processing chip degradation, and power supply voltage regulation failures in variable-frequency environments.
EDHARD Temperature and Pressure Transmitters
Analog transmitter modules for process monitoring in injection molding, chemical reactors, and thermal processing. Repair challenges include calibration drift from PCB corrosion, transmitter failure under thermal cycling, and 4-20mA loop instability from connector resistance.
EDHARD Solenoid Driver and Valve Control Boards
Power switching and solenoid driver boards for pneumatic and hydraulic valve actuation in industrial automation. Common faults include MOSFET or IGBT switching device failure under surge conditions, gate drive circuit malfunction, and flywheel diode degradation in high-cycle applications.
EDHARD Industrial Connector and Cable Assemblies
Ruggedized M12 and custom connector systems for field-mounted sensors and distributed I/O in automotive and machinery plants. Failure modes include pin corrosion, impedance mismatch in high-frequency signal lines, and water ingress through degraded cable jackets in monsoon-prone Indian regions.
EDHARD Compact PLC and Logic Modules
Modular micro-PLC and discrete logic modules for standalone machine control without networked infrastructure. Repair focus includes firmware corruption, I/O relay failures, power supply voltage regulation under load transients, and backlighting failure in integrated operator panels.

Common EDHARD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EDHARD equipment arriving at our workshop.
- ✓EDHARD proximity sensor oscillator circuit failure — Humidity ingress into sealed sensor housing causes capacitor leakage and oscillator tank circuit damping in coastal or high-moisture Indian factory environments. Moisture corrosion of PCB traces and component leads degrades signal generation.
- ✓EDHARD solenoid driver MOSFET or IGBT gate drive failure — High-frequency PWM switching in high-amperage solenoid circuits causes thermal cycling stress on gate drive capacitors and isolated gate driver ICs. Surge voltage spikes from inductive loads degrade gate oxide in power switching devices.
- ✓EDHARD 4-20mA transmitter output stuck or unstable — Loop resistance increases from corroded connector pins and cabling in humid industrial sites, or D/A converter IC failure from thermal shock during process cycling. Capacitor aging in signal conditioning circuit causes frequency response degradation.
- ✓EDHARD control interface module relay contact welding or chatter — High-current switching transients exceed relay contact rating under fault conditions. Sustained arcing from high-frequency PWM currents causes contact material migration and surface oxidation. Vibration from adjacent machinery causes mechanical chatter.
- ✓EDHARD temperature transmitter calibration drift over time — Pt100 RTD sensor poisoning from industrial atmosphere contaminants or sensor lead resistance increase from terminal oxidation. Reference resistor network aging and op-amp offset voltage drift in signal conditioning circuit degrade accuracy.
- ✓EDHARD M12 connector pin corrosion and intermittent signal loss — Moisture and salt air ingress causes electrochemical corrosion of gold-plated contact pins and tin-plated socket barrels in coastal Indian manufacturing zones. Repeated mating cycles cause microscopic scratches allowing corrosion initiation.

Frequently Asked Questions — EDHARD Repairs
Do you repair EDHARD equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full EDHARD product range across India — proximity sensors, control modules, transmitters, solenoid drivers, and PLC modules. We offer PAN India pickup and drop service from all major industrial cities: Mumbai, Pune, Delhi, Bangalore, Hyderabad, Chennai, Kolkata, Ahmedabad, Jaipur, and Chandigarh. All repairs are performed in our Vadodara, Gujarat facility with 180+ qualified engineers.
What is the typical turnaround time for EDHARD proximity sensor repair?+
Standard diagnostics and repair of EDHARD proximity sensors takes 3-5 working days. Expedited repair (24-48 hours) is available for critical production downtime situations at nominal premium. We provide daily status updates and issue detailed technical reports explaining failure root cause and remedial action taken to prevent recurrence.
Can Synchronics repair EDHARD modules with corroded M12 connectors?+
Absolutely. Salt-air and moisture corrosion of EDHARD M12 connector pins is common in coastal Indian plants. Synchronics cleans corroded pins using precision cleaning agents and burnishing, replaces severely corroded connectors with genuine EDHARD or equivalent industrial-grade M12 sockets, and applies silicone grease protection. We pressure-test repaired connectors to verify IP67/IP69K sealing integrity.
Do you stock EDHARD spare parts and replacement modules?+
We maintain inventory of common EDHARD modules, relay cards, connector kits, and sensor components for quick-turnaround repairs. For obsolete EDHARD components, Synchronics identifies cross-compatible industrial alternatives from Turck, Festo, Pilz, and similar manufacturers that interface seamlessly with your existing equipment and wiring. Custom circuit board repairs are available when spares are unavailable.
What warranty do you provide on EDHARD repairs?+
Synchronics provides 12-month parts and labor warranty on all EDHARD repairs. If equipment fails due to defective repair within warranty period, we provide free re-repair and shipping. We also issue detailed calibration and performance testing certificates for critical modules used in regulated food, pharmaceutical, or automotive OEM supply environments.
How do I send my EDHARD 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 EDHARD 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 EDHARD 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 EDHARD 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.
