HOHNER Product Lines We Repair
Our engineers are trained on the full HOHNER product range. Below are the major product families we service.
Hohner Solenoid Valves
Directional control solenoid valves used in pneumatic and hydraulic automation. Common faults include coil burnout, valve stiction, and pilot pressure leakage affecting production line response times and cycle accuracy.
Hohner Relay Modules and Contactors
Industrial-grade electromagnetic contactors and relay switching units for motor control and power distribution. Frequent issues: contact wear, coil insulation breakdown, and armature sticking causing intermittent equipment shutdown.
Hohner Electromechanical Timers
Precision time-delay relay modules for synchronization in textile machinery, packaging lines, and batch processing. Common failures: mechanical wear in timer mechanisms, contact corrosion, and accuracy drift over extended cycles.
Hohner Limit Switches and Position Sensors
End-of-travel and position detection switches for machine tool automation and material handling equipment. Typical faults: contamination ingress, spring fatigue, and electrical contact oxidation in harsh industrial environments.
Hohner Pneumatic Actuators and Cylinders
Industrial pneumatic linear and rotary actuators with integrated solenoid pilot control for automated assembly and material transfer. Repair needs: seal degradation, rod corrosion, and solenoid valve internal wear affecting speed and precision.

Common HOHNER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HOHNER equipment arriving at our workshop.
- ✓Solenoid coil burnout - no response to control signal — Hohner solenoid coils fail due to sustained high current draw, moisture ingress into winding insulation, or incorrect voltage supply. Thermal cycling in textile mills accelerates coil degradation.
- ✓Valve stiction and sluggish directional response — Hohner solenoid valve spools stick due to particulate contamination in hydraulic/pneumatic lines, corrosion on precision piston surfaces, or hardened seal residue. Common in steel mills with poor filtration.
- ✓Relay contact chattering and electrical arcing — Hohner electromagnetic contactors experience contact erosion and pitting after thousands of electrical cycles, causing intermittent arcing and dropout. Overload current and inductive switching surges accelerate contact wear.
- ✓Timer module inaccuracy and drift - cycles not synchronized — Hohner electromechanical timers lose accuracy due to mainspring tension loss, gear train wear, or contact bounce in the switching mechanism. Temperature variations in production environments worsen timing drift.
- ✓Limit switch contact oxidation and intermittent signal loss — Hohner position switches in humid environments (textiles, chemical plants, steel) suffer contact oxidation and corrosion, particularly at switch closure points. Vibration-induced micro-arcing accelerates contact surface degradation.
- ✓Pneumatic cylinder seal leakage and reduced output force — Hohner pneumatic actuators experience seal degradation from exposure to moisture, thermal cycling, and abrasive particulate in compressed air. Rod pitting from corrosion reduces seal contact pressure.

Frequently Asked Questions — HOHNER Repairs
Do you repair Hohner equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete Hohner product range including solenoid valves, electromagnetic contactors, relay modules, timers, limit switches, and pneumatic actuators. We offer door pickup from all major Indian cities - Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and across India. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat.
What is the typical turnaround time for Hohner solenoid valve repair?+
Standard Hohner solenoid valve repairs take 5-7 working days including diagnostic testing, coil resistance measurement, spool cleaning, seal replacement, and final pressure-cycle validation. Urgent repairs with expedited testing can be completed in 2-3 days. We provide real-time repair status updates to all customers.
Can Synchronics repair Hohner electromechanical contactors with non-standard coil voltages?+
Absolutely. Hohner contactors with 24V DC, 110V AC, 230V AC, and 380V AC coils are regularly repaired at Synchronics. Our technicians perform voltage identification, coil winding inspection, and supply correct replacement coils matching your exact nameplate specification. We maintain stock of common Hohner coil variants for rapid turnaround.
Do you provide genuine Hohner spare parts or equivalent alternatives?+
Synchronics uses OEM-equivalent components meeting Hohner's original engineering specifications - including silver-cadmium contacts, elastomer seals, and precision springs. We source from authorized distributors and validate all parts against original Hohner documentation. Genuine Hohner spare parts are also procured on customer request with extended lead times.
What warranty do you offer on Hohner equipment repairs?+
All Hohner repairs from Synchronics carry a 12-month warranty covering defects in workmanship and parts failure under normal operating conditions. We provide detailed test reports and calibration certificates for every repaired unit. Extended warranty options are available for critical production equipment in textile mills and automotive facilities.
How do I send my HOHNER unit for repair?+

What is the cost of repairing a HOHNER 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 HOHNER 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 HOHNER 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.
