OPTEX Equipment We Repair — By Category
OPTEX Product Lines We Repair
Our engineers are trained on the full OPTEX product range. Below are the major product families we service.
OPTEX Photoelectric Sensors
Through-beam, retroreflective, and diffuse OPTEX sensors used in conveyor sorting, part detection, and positioning applications. Common failures include LED aging, lens clouding from dust/moisture, amplifier threshold drift, and output transistor burnout from electrical transients.
OPTEX Safety Laser Scanners (SLS)
Compact safety-rated laser scanning sensors for area monitoring, collision avoidance, and personnel protection in automated production environments. Repairs address laser tube degradation, mirror scanning failure, analog signal noise, and safety-rated output intermittency.
OPTEX Displacement and Distance Sensors
Optical displacement, distance, and color/contrast detection sensors for high-precision positioning and material identification in food, pharmaceutical, and automotive assembly. Common defects include analog output linearity loss, target reflectivity sensitivity shifts, and signal conditioning circuit failures.
OPTEX Proximity and Presence Sensors
Long-range optical proximity and object presence detection for material handling, packaging, and palletizing systems. Repairs include oscillator frequency drift, background light rejection circuit tuning, and connector corrosion causing intermittent detection.
OPTEX Fiber Optic Sensors
Miniature fiber-coupled photoelectric and displacement sensors for tight spaces, high-temperature zones, and electromagnetic noise-prone areas in steel mills and foundries. Issues include fiber end face contamination, light coupling efficiency loss, and amplifier gain degradation.

Common OPTEX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in OPTEX equipment arriving at our workshop.
- ✓LED degradation and reduced light output — OPTEX photoelectric sensors use LEDs with finite lifetime, typically 50,000-100,000 operating hours. In harsh industrial environments with thermal cycling, moisture, and vibration, LED brightness declines, causing detection range loss and erratic switching. This manifests as intermittent object detection or complete sensor failure in conveyor and sorting applications.
- ✓Lens and optical window contamination — Dust, oil vapor, condensation, and particulate accumulation on OPTEX sensor lenses is endemic in Indian manufacturing facilities, particularly in textile mills, grain silos, and automotive assembly. Contamination blocks incident light and reflected signals, reducing effective detection range by 50-80% and causing false negatives.
- ✓Safety laser scanner mirror deflection failure — OPTEX SLS units (OS32C, OS35C, OS51) use rotating mirrors for 180° or 270° scanning. Mirror bearings wear from continuous operation, and piezo-electric scanning elements drift or fail from thermal stress. Result: incomplete scan pattern, dead zones in safety perimeter, and loss of safety certification.
- ✓Analog output drift and linearity loss — OPTEX displacement and distance sensors (OP-Z3, OP-DM series) rely on precision analog signal conditioning. Capacitor aging, op-amp offset drift, and temperature coefficient changes degrade 4-20mA or 0-10V output linearity. Conveyor speed feedback and positioning systems lose accuracy, causing product misalignment or layer slippage.
- ✓Safety laser scanner unsafe state (loss of safety output) — OPTEX SLS safety outputs intermittently fail or remain asserted due to safety relay circuit degradation, solder joint cold cracking from thermal shock, or watchdog timer firmware corruption. This violates safety integrity and forces emergency shutdown of automated lines until equipment is repaired.
- ✓Fiber optic coupling loss and signal weakness — OPTEX fiber-optic sensors (OP-87F, OP-FFD series) are prone to fiber end face dirt and micro-cracking from repeated insertion/removal during maintenance. Light coupling efficiency drops by 10-40%, reducing detection range and sensitivity. Common in steel mills and foundries where fiber connectors are frequently disconnected.

Frequently Asked Questions — OPTEX Repairs
Do you repair OPTEX equipment anywhere in India?+
Yes. Synchronics repairs the full OPTEX product range — photoelectric sensors, safety laser scanners, displacement sensors, proximity sensors, and fiber-optic detection units. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all major industrial cities. Same expert facility in Vadodara, Gujarat. Turnaround is typically 3-7 days for non-safety critical units and 2-3 days for safety-rated SLS repairs.
What OPTEX sensor faults can you diagnose without physical repair?+
Our engineers conduct non-destructive diagnosis of OPTEX sensors using precision test equipment: optical power meters for LED/laser output, sensitivity curve plotting, analog output linearity measurement, and safety function verification. We provide detailed fault reports before repair authorization, saving you time and cost if the unit is beyond economical repair. This is especially valuable for safety laser scanners, where diagnostic certainty ensures compliance.
Can you repair OPTEX safety laser scanners (SLS) and maintain safety certification?+
Yes. Synchronics repairs OS32C, OS35C, OS51, OS32E, and OS35E OPTEX safety scanners with full safety integrity. All repairs comply with ISO 61496 safety standards. We replace safety-critical components with genuine or approved substitutes, perform mandatory safety function testing (response time, blind zone verification, fault detection), and provide repair certificates documenting safety-rated re-commissioning. Your repaired scanner can be returned to production with full confidence in safety compliance.
How long do OPTEX photoelectric sensor LEDs typically last, and when should I replace them?+
OPTEX photoelectric sensor LEDs are rated for 50,000-100,000 operating hours depending on model and duty cycle. In continuous 24/7 operation, that is 5-11 years. However, thermal cycling, moisture, and electrical transients (common near servo drives and VFDs) accelerate degradation. Synchronics recommends proactive LED replacement at 30,000-40,000 hours or if optical output drops below 80% of specification. We can retrofit your existing sensors with upgraded LED modules for extended lifespan.
What is the cost difference: repair versus replacement for OPTEX sensors?+
OPTEX sensor replacement cost in India ranges from Rs 8,000 to Rs 50,000+ depending on model and type (safety SLS scanners are premium). Synchronics repairs typically cost 40-60% of replacement, excluding downtime savings. For high-volume sensor installations (conveyor systems, material handling lines), repair is almost always economical. Additionally, repair preserves your sensor configuration and reduces procurement delays common with new equipment sourcing in India.
How do I send my OPTEX 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 OPTEX 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 OPTEX 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 OPTEX 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.
