BEI ELECTRONICS Product Lines We Repair
Our engineers are trained on the full BEI ELECTRONICS product range. Below are the major product families we service.
Incremental Encoders (Optical)
BEI optical incremental encoders provide real-time shaft position feedback for motion control and speed monitoring. Common failures include optical disc contamination, LED aging, and photodetector degradation affecting pulse quality and counting accuracy.
Absolute Multi-Turn Encoders
BEI absolute encoders capture total cumulative shaft rotation without zero-reference loss. Typical repair issues include battery backup failures in battery-backed absolute units, gear train slippage in multi-turn mechanisms, and data corruption in non-volatile memory.
Resolvers (Brushless Synchro)
BEI precision resolvers deliver analog sin-cos feedback for servo and drive systems requiring continuous angle measurement. Common faults include stator winding insulation breakdown, rotor bearing wear causing runout, and excessive phase shift in excited frequency response.
Shaft Coupling and Mounted Assemblies
BEI offers pre-assembled encoder and resolver units with precision shaft couplings for direct machine mounting. Failures often stem from coupling misalignment, shaft runout exceeding specifications, and bearing preload loss over time.
Signal Conditioning and Interface Modules
BEI signal conditioners convert raw encoder/resolver outputs to standardized industrial protocols (SSI, CANopen, EtherCAT). Repair focuses on output amplifier failures, voltage regulation faults, and communication signal integrity restoration.
Magnetic Encoders (Non-Contact)
BEI magnetic encoders eliminate optical disc contamination issues common in dusty mills and outdoor environments. Typical failures include Hall effect sensor degradation, magnet demagnetization, and air-gap drift causing signal loss.

Common BEI ELECTRONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BEI ELECTRONICS equipment arriving at our workshop.
- ✓Optical disc contamination causing zero-pulse loss — Dust, oil vapors, or moisture ingress into BEI optical encoder housing. Common in textile mills, paper plants, and food processing where airborne contaminants settle on the encoder disc and photodetector lens.
- ✓Resolver output signal phase shift or amplitude loss — BEI resolver stator winding insulation breakdown or partial short circuits, typically caused by thermal cycling or contaminated cooling air. Rotor bearing wear increases signal jitter.
- ✓Multi-turn encoder battery backup depletion or failure — BEI DHM series absolute encoders use lithium backup batteries that degrade over 5-7 years or fail prematurely in high-temperature environments. Corroded battery connectors prevent charging.
- ✓Incremental encoder counting errors or pulse dropout — LED aging in BEI optical encoders reduces light intensity, or photodetector circuit sensitivity degrades. Shaft coupling runout exceeding tolerance can cause photodetector misalignment.
- ✓Magnetic encoder air-gap drift or sensor dropout — BEI magnetic encoders rely on fixed air-gap between rotor magnet and Hall sensor. Bearing wear, shaft deflection, or mounting bracket relaxation increases gap beyond the 2-3mm tolerance window.
- ✓SSI or CANopen interface module communication timeout — BEI signal conditioner output stage failure, excessive cable capacitance, or encoder signal too weak for reliable digital conversion. Clock or data line short circuits.

Frequently Asked Questions — BEI ELECTRONICS Repairs
Do you repair BEI Electronics equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full BEI Electronics product range — including optical encoders, absolute multi-turn encoders, resolvers, and signal conditioning modules. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs are processed at our ISO 9001 certified facility in Vadodara, Gujarat, with fast 3-5 day turnaround for urgent breakdowns.
What BEI encoder models do you most commonly repair in Indian mills?+
Synchronics repairs all BEI H25D, H25E, HS35D optical incremental encoders used in textile spindles and loom automation. We also handle BEI DHM506 and DHM510 absolute encoders in sugar mill crush roll drive systems. Resolver repairs focus on BEI 14-pole brushless synchro units in heavy press and rolling mill servo feedback loops. Contact us with your specific model number for immediate diagnostic and cost estimate.
Why do BEI optical encoders fail in dusty manufacturing environments?+
BEI optical encoders use internal LED light sources and photodetectors separated by a rotating glass disc. In textile mills, sugar plants, and cement facilities, airborne dust and oil vapor accumulate on the disc and lens over 2-3 years, blocking light transmission. This causes pulse dropout and counting errors. Synchronics provides professional cleaning and re-sealing to restore optical performance, or upgrades to BEI magnetic non-contact encoders for permanently dusty locations.
Can you replace BEI encoder batteries and restore absolute position retention?+
Yes. BEI DHM series absolute encoders use internal lithium backup batteries to retain position data during power loss. Synchronics accesses the battery compartment, tests and replaces failed or depleted cells with OEM equivalent lithium batteries, and verifies the absolute reference remains intact. We also clean corrosion from battery contacts to ensure reliable charging. Your encoder will retain position accuracy for another 5-7 years.
What testing and certification do you provide after BEI encoder repair?+
Synchronics performs comprehensive testing on all repaired BEI equipment using precision test fixtures and certified measurement tools. For encoders we verify pulse count accuracy, electrical continuity, signal rise-time and amplitude. For resolvers we measure sin-cos phase and magnitude at standard excitation frequency. All repairs include a test report and 12-month warranty. We do not return any BEI equipment to your plant until it meets original specification.
How do I send my BEI ELECTRONICS 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 BEI ELECTRONICS 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 BEI ELECTRONICS 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 BEI ELECTRONICS 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.
