EUCHNER Product Lines We Repair
Our engineers are trained on the full EUCHNER product range. Below are the major product families we service.
MGB Series Multi-Function Switches
Modular safety switches combining mechanical and electronic locking with multiple contact combinations. Common faults include contact erosion, mechanical latch wear, solenoid coil degradation, and encoder signal loss affecting safety certification.
AZM Modular Safety Switches
Compact coded safety switches with mechanical and electronic interlocking for machinery access control. Typical issues involve coded key blade wear, actuator solenoid failure, and electronic module communication loss.
EB Series Electronic Blade Switches
Electronic safety switches for hinged or sliding guards with integrated diagnostics and safety-rated outputs. Common failures include blade actuator misalignment, capacitive sensor drift, and safety relay circuit faults.
TP Series Coded Safety Switches
Electronically coded safety actuators preventing unauthorized bypass or key substitution. Repair challenges include EEPROM corruption, actuator wear, and wireless communication interference on networked systems.
AGS Series Angular Safe Switches
Angular safety sensors for rotating shaft monitoring and emergency stop integration. Issues involve mechanical wear on cam followers, magnetic sensor misalignment, and electronic signal conditioning failures.
MGB-R Rotary Safety Switches
Compact safety switches for rotary guards and rotating machinery with integrated mechanical interlocking. Common defects include roller bearing degradation, contact wear under high switching loads, and seal failure leading to contamination.

Common EUCHNER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EUCHNER equipment arriving at our workshop.
- ✓Safety latch mechanical wear and non-engagement — Euchner MGB and AZM mechanical interlocks undergo repeated engagement cycles. Latch wear, spring fatigue, and contamination prevent full mechanical lock engagement, creating safety certification gaps. Solenoid actuators may not provide sufficient force over time.
- ✓Coded key blade wear and key substitution risk — TP Series coded safety switches use mechanical key blade patterns to prevent unauthorized bypass. Repeated insertion/extraction causes blade wear, groove deformation, and key binding, compromising the safety-coding mechanism and allowing foreign key activation.
- ✓Solenoid coil open-circuit and latch failure-to-unlock — Euchner solenoid actuators in MGB, AZM, and EB switches operate continuously. Thermal cycling, humidity ingress, and manufacturing defects cause coil insulation breakdown, resulting in open-circuit faults and mechanical latch seizure.
- ✓Electronic module signal loss and safety relay dropout — Euchner EB and AZM electronic modules contain capacitive sensors, signal conditioning circuits, and safety relay contacts exposed to vibration, electrical noise, and thermal stress in factory environments. Component solder joint cracking and IC failure cause intermittent or permanent signal loss.
- ✓Capacitive sensor drift and false-positive machine lockouts — EB Series electronic blade switches employ capacitive proximity sensors to detect guard movement. Humidity, contamination, metal proximity, and thermal drift degrade sensor calibration, causing false lockouts or failure-to-detect guard opening.
- ✓EEPROM corruption and loss of coded safety identity — TP Series and networked Euchner safety switches store coded security keys and configuration data in EEPROM memory. Voltage spikes, failed firmware updates, and electromagnetic interference corrupt stored codes, causing the device to reject all keys and lock out machine operation.

Frequently Asked Questions — EUCHNER Repairs
Do you repair Euchner safety switches and interlocks across India?+
Yes. Synchronics repairs all Euchner product lines — MGB multi-function switches, AZM modular safety switches, EB electronic blade switches, TP coded switches, and AGS angular sensors. We offer PAN-India door-to-door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and across all industrial regions. All repairs are carried out at our Vadodara, Gujarat facility with full ISO 13849-1 safety compliance testing.
Can Synchronics repair Euchner safety switches without losing machine certification?+
Absolutely. Euchner safety devices are safety-critical components requiring compliance with ISO 13849-1, EN 954-1, and machinery directives. Synchronics employs certified safety engineers who repair and validate all Euchner switches to original safety specifications. We provide test reports documenting functional safety compliance, enabling you to maintain machine certification and operator safety liability.
What is the typical turnaround time for Euchner interlock repair?+
Standard Euchner safety switch repairs take 7-10 working days including diagnostics, component replacement, calibration, and full functional safety testing. Critical production stoppages can be expedited to 48-72 hours. Complex issues like EEPROM corruption may require coordination with Euchner Germany for code recovery. Synchronics provides real-time status updates and interim loaner equipment for emergency uptime.
Why do Euchner coded safety switches fail repeatedly after repair?+
TP Series coded switch failures often stem from downstream issues: contamination entering the blade slot, solenoid mounting loose after vibration, or inadequate actuator reset. Synchronics performs root-cause analysis identifying mechanical wear, environmental factors, and installation errors. We replace worn components, optimize mounting, and provide maintenance protocols to prevent recurrence. We also verify that replacement solenoid drivers match OEM activation profiles.
Does Synchronics stock Euchner spare parts for emergency repairs?+
Synchronics maintains inventory of common Euchner components including solenoid coils, mechanical latches, capacitive sensors, coded blades, and electronic modules. For rare or fast-moving parts, we coordinate directly with Euchner authorized distributors in India to minimize delay. We can often achieve same-city emergency delivery through local supply partnerships in Pune, Chennai, Delhi, and Mumbai industrial zones.
How do I send my EUCHNER 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 EUCHNER 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 EUCHNER 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 EUCHNER 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.
