Expert repair of Hamlin reed relays, sealed switches, and electromagnetic sensing devices across all industrial sectors.
HAMLIN Product Lines We Repair
Our engineers are trained on the full HAMLIN product range. Below are the major product families we service.
Reed Relay Modules
Hermetically sealed reed switch assemblies used for signal switching in control circuits. Common failures include contact stiction, coil opens, and sealed chamber leaks causing contact oxidation and performance drift.
Solid-State Relay (SSR) Packages
Opto-coupled solid-state switching solutions for AC and DC loads. Typical issues include triac failure, input LED degradation, heat dissipation problems in tropical Indian climates, and gate-drive circuit failures.
Proximity and Position Sensors
Magnetically actuated sensing switches for machinery position detection and limit applications. Failures manifest as erratic switching, loss of sensitivity, connector corrosion, and ambient magnetic field interference in steel mill environments.
Sealed Electromagnetic Switches
Rugged, hermetically sealed switching devices for harsh industrial duty. Common repair needs include contact welding under heavy inductive loads, coil winding insulation breakdown, and seal deterioration in high-humidity textile factories.
Custom Relay Assemblies and Hybrid Modules
Application-specific Hamlin switching solutions combining multiple reed relays and driver circuitry. Repair challenges include PCB trace corrosion, potting compound cracking in thermal cycling, and solder joint fatigue at connector interfaces.

Common HAMLIN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HAMLIN equipment arriving at our workshop.
- ✓Reed switch contact stiction and permanent closure — Hamlin reed switches can experience contact welding or stiction when switching high inductive currents without proper suppression. Over time, contact surfaces oxidize or adhere, causing the switch to remain closed even after the magnetic field is removed.
- ✓Sealed chamber internal oxidation and fogging — Hamlin's hermetically sealed reed switches maintain an inert nitrogen atmosphere. Breach of the seal (via connector corrosion or mechanical stress) allows moisture and oxygen ingress, oxidizing contacts and creating internal fogging that blocks the reeds from actuating properly.
- ✓Coil open circuit and low pull-in voltage — Hamlin electromagnetic coils fail due to insulation breakdown from thermal cycling, vibration-induced wire fracture, or manufacturing defects in enamel coating. High-humidity Indian facilities (especially textile and chemical plants) accelerate insulation degradation.
- ✓Solid-state relay triac short circuit and thermal runaway — Hamlin SSR triacs fail when subjected to voltage spikes, high dV/dt transients, or inadequate heat dissipation in hot Indian manufacturing environments. A shorted triac causes the relay to lock on, risking load damage and fire hazard.
- ✓Proximity sensor loss of sensitivity and chatter — Hamlin magnetically actuated position sensors lose sensitivity due to coil contamination (ferrous dust accumulation), mechanical seal wear exposing the sensing element to moisture, or stray magnetic fields from nearby transformers and motor drives.
- ✓PCB trace corrosion and connector green rot in hybrid modules — Hamlin custom relay assemblies potted in conformal coating are susceptible to ionic corrosion under PCB traces when exposed to salt spray (coastal Indian plants) or process chemical vapors. Connector pins develop green patina and increase contact resistance.

Frequently Asked Questions — HAMLIN Repairs
Do you repair Hamlin equipment anywhere in India?+
Yes. Synchronics repairs the full Hamlin product range — reed relays, solid-state relays, proximity sensors, sealed switches, and custom hybrid modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and all other cities. All repairs are performed in our certified facility in Vadodara, Gujarat, with same-day diagnostics and same-week turnaround for most Hamlin failures.
Why do Hamlin reed switches fail prematurely in Indian textile mills?+
Indian textile mills expose Hamlin switches to high humidity, airborne lint particles, temperature swings, and vibration from heavy looms. Moisture breaches the hermetic seal, oxidizing contacts internally. Additionally, unfiltered inductive loads (motor contactors, solenoids) cause contact welding without proper arc suppression. Synchronics retrofits your Hamlin assemblies with snubber networks and improved connectors rated for tropical climates, extending reed switch life by 3-5 years.
Can you repair Hamlin solid-state relays or must we always replace them?+
Most Hamlin SSR failures are economical to repair. Failed triacs, input LEDs, and driver circuits are individually replaceable if the PCB is sound. Synchronics tests all Hamlin SSRs under load before shipment and replaces only the failed component, not the entire module — saving 40-60% versus OEM replacement. For high-current Hamlin SSRs handling heavy industrial loads, we often recommend new units to ensure safety warranty.
What is the turnaround time for Hamlin relay repairs at Synchronics?+
Hamlin reed relay modules and sealed switches typically receive same-day diagnostics (electrical testing and reed continuity checks). Simple repairs — contact cleaning, connector replacement, coil testing — ship within 3-5 business days. Complex failures requiring potting, seal replacement, or custom winding take 7-10 days. We maintain buffer stock of common Hamlin modules (HE3620, HE3621, SSR packages) for emergency loan units while your original equipment is being repaired.
Does Synchronics offer preventive maintenance services for Hamlin control systems?+
Yes. Synchronics provides on-site inspection and predictive maintenance for Hamlin relay panels, sensor networks, and switching assemblies at Indian manufacturing facilities. We perform helium leak testing, contact resistance trending, coil resistance tracking, and thermal imaging of SSR heat sinks. This proactive approach catches seal failures, coil degradation, and corrosion before catastrophic downtime occurs — especially valuable in 24/7 chemical plants and steel mills.
How do I send my HAMLIN 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 HAMLIN 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 HAMLIN 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 HAMLIN 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.
