The RS-8116-6A Wire Bending Tester is a six-station testing machine for repeated angular durability testing of TWS earphone ear hooks and compatible wire assemblies. Each station operates independently using a Panasonic AC servo motor. The system supports adjustable test angles, speeds and cycle counts, with online impedance monitoring and automatic station stop when preset electrical limits are exceeded.
The ITM-LAB RS-8116-6A Wire Bending Tester is a six-station system for repeated angular durability testing of wire-related components, including TWS earphone ear hooks. Each station uses an independent servo drive. Programmable test conditions and online impedance monitoring allow operators to evaluate mechanical cycling and electrical changes during testing.
The RS-8116-6A is documented for repeated twist testing of TWS earphone ear hooks. Other wire-related components may be tested when their dimensions, fixtures and required movement are compatible with the machine.
Applications for configuration review include:
TWS Earphone Ear Hooks: Repeated angular movement and electrical monitoring.
Flexible Wire Assemblies: Durability testing under defined bending or rotational conditions.
Cable-to-Component Connections: Evaluation of electrical changes during repeated movement.
Custom Electronic Components: Fixture-based angular cycling according to an OEM procedure.
For USB cables, flat cables and multi-core cables, the required test movement and fixture arrangement must be confirmed before selecting this model.
Six Panasonic AC servo motors and Shimpo planetary reducers provide independent movement control for each station.
Operators can configure test angle, rotational speed, target cycles and pause conditions through the touchscreen.
The monitoring system measures electrical impedance during testing. When a value exceeds its configured limits, the corresponding station stops and indicates the event.
An OMRON touchscreen and MITSUBISHI PLC control the test process. A THINGET touchscreen supports impedance monitoring and limit settings.
The RS-8116-6A consists of a six-station testing unit and a separate control cabinet.
The main testing unit includes independent rotary stations, specimen fixtures, electrical monitoring connections and an enclosed testing area.
The control cabinet houses the touchscreen interfaces, station controls and emergency stop.
The test fixture determines how the programmed angular movement is applied to the specimen. Fixture selection must therefore follow the specimen drawing and required test procedure.
The RS-8116-6A applies repeated angular movement to a mounted specimen while monitoring its electrical condition.
Step 1 — Mount the Specimen
Secure the specimen in the appropriate fixture and connect the required electrical monitoring leads.
Step 2 — Set the Test Parameters
Enter the movement angle, rotational speed, target cycle count and pause conditions.
Step 3 — Start Repeated Movement
The servo-driven station performs the programmed angular motion.
Step 4 — Monitor Electrical Response
The impedance monitoring system compares measured values with the configured upper and lower limits.
Step 5 — Record the Test Result
If a monitored value exceeds the limits, the corresponding station stops and indicates the event. The completed cycle count can be recorded for evaluation.

Note: Specifications are based on the RS-8116-6A technical document. Confirm the required test angle, fixture configuration and electrical monitoring requirements before ordering.
Repeated angular movement can affect the electrical and mechanical condition of a wire-related component.
A conductor or electrical connection becomes open during repeated movement.
Measured electrical impedance exceeds the configured acceptance limits.
Repeated movement affects a conductor termination or connection area.
Cracking, deformation or other visible damage develops in the specimen.
The RS-8116-6A monitors electrical impedance and indicates limit-exceeding events. Mechanical damage must be assessed through specimen inspection or additional measurements.
Wire bending, cable flexing and cable torsion tests apply different forms of mechanical movement. The equipment should be selected according to the specimen and required test method.

The RS-8116-6A technical document identifies an Apple Inc. test SOP as the design basis for TWS earphone ear-hook twist testing.
Customer / OEM Test Procedures
Define the specimen, movement angle, speed, test cycles, electrical limits and acceptance criteria.
Cable and Connector Test Standards
May specify particular bending or torsion methods, fixtures and loading conditions. Applicability must be verified against the actual test arrangement.
Confirm the required standard and revision before selecting the machine. Repeated angular movement alone does not establish compliance with a specific cable testing standard.
Configuration selection begins with the specimen and test procedure.
Before requesting a quotation, confirm:
Specimen: Product type, dimensions and drawing
Test Movement: Bending or twisting direction and angle
Test Speed: Required rotational speed
Test Cycles: Target repetitions and counting definition
Electrical Monitoring: Number of circuits and impedance limits
Fixture: Clamping positions and specimen mounting requirements
Test Quantity: Number of specimens tested per run
Acceptance Criteria: Electrical and mechanical failure conditions
For example, a TWS earphone ear hook and a USB cable assembly may require different fixtures and movement definitions.

The RS-8116-6A performs repeated angular durability testing of mounted components. Its documented application is TWS earphone ear-hook twist testing. Other wire-related specimens require fixture and test-method confirmation.
The machine has six independently driven stations. Up to six specimens can be tested when the selected fixtures and specimen dimensions allow one specimen per station.
Yes. Each station can operate and stop independently. A station stops when its monitored impedance exceeds the configured limits.
The documented test speed is 1–60 rpm with a stated tolerance of ±0.5 rpm.
The machine monitors electrical impedance during mechanical cycling. When a monitored value exceeds the configured limits, the corresponding station stops and indicates the event. The physical cause should be confirmed through inspection or further electrical testing.
The documented common configurations are 0 to ±95° or 0 to ±180°. The applicable angle depends on the fixture and test setup.
Testing may be possible with compatible fixtures and procedures. The supplied RS-8116-6A documentation specifically covers TWS earphone ear hooks, so suitability for USB and multi-core cables must be confirmed before ordering.
Wire bending testing applies a defined bending or angular movement. Cable torsion testing applies twisting around an axis. The distinction depends on the fixture and specimen motion, not only the equipment name.
Provide the specimen drawing, dimensions, movement angle, speed, cycle count, electrical monitoring requirements and applicable test procedure. These details support fixture and equipment configuration.
