Servo-Controlled Cable Flex Life Testing with Real-Time
TheRS-8116-6B Cable Bending Tester is designed to evaluate the bending durability and electrical reliability of cables, wires, connectors, and cable assemblies under repeated flexing.
With six independent test stations, servo-controlled bending, and real-time impedance monitoring, the system can detect electrical changes during the flex test rather than relying only on manual inspection after testing.
It is suitable for USB cables, charging cables, earphone cables, data cables, signal cables, multi-core cables, and other flexible cable assemblies used in electronics and electrical products.
The RS-8116-6B Cable Bending Tester is designed for repeated flex-life and electrical reliability testing of cables that experience frequent bending during everyday use.
Typical Test Specimens
Earphone Cables
USB Cables
Charging Cables
Flex-life testing around cable ends and connectors.

Repeated bending evaluation for charging cable assemblies.
Data Cables
Multi-Core Cables
Signal & Communication Cables
Monitor electrical performance during repeated flexing.

From consumer electronics cables to multi-core assemblies, the RS-8116-6D combines repeated bending with real-time electrical monitoring.
How Does a Cable Bending Test Work?
Cable bending testing simulates the repeated flexing a cable experiences during everyday use. The RS-8116-6B combines controlled mechanical bending with real-time electrical monitoring to evaluate both flex life and conductor reliability.
Test Process
01 — FIX & LOAD
02 — SET PARAMETERS
03 — REPEATED BENDING
04 — MONITOR IMPEDANCE
05 — DETECT & RECORD
Secure the cable and apply the specified load.
Set angle, speed, cycles and electrical limits.
Servo-controlled left/right bending begins.
Continuously monitor electrical resistance.
Detect abnormal conditions and record failure cycles.
What Does the Test Tell You?
The test determines not only how many bending cycles the cable can withstand, but also when its electrical performance begins to deteriorate.
Mechanical Flexing → Electrical Monitoring → Failure Detection → Test Data
Real-Time Impedance Monitoring
Detect Electrical Failure During the Flex Test
Mechanical appearance alone does not always reveal cable failure.
Repeated bending may cause internal conductor fatigue, partial strand breakage, unstable electrical contact, or eventually complete conductor failure while the external cable jacket still appears intact.
The RS-8116-6B combines mechanical bending with real-time electrical monitoring.
Depending on the configured test method, operators can define electrical monitoring criteria such as:
Reference resistance
Upper resistance limit
Lower resistance limit
Allowed resistance change
Failure threshold
During testing, the system continuously monitors the electrical condition of the specimen.
When a configured failure condition is reached, the corresponding station can be identified and the abnormal test condition recorded.
Why This Matters
A conventional flex-life test may tell you:
“The cable completed 50,000 bending cycles.”
Electrical monitoring helps answer the more important question:
“Was the cable still electrically reliable after those 50,000 cycles?”
This makes the RS-8116-6B particularly useful for cable assemblies where electrical continuity and mechanical durability must be evaluated together.
Six Independent Test Stations
The RS-8116-6B features six test stations for simultaneous cable durability testing. Each station operates independently, allowing multiple specimens to be evaluated under controlled test conditions without unnecessary interruption.
Built for Higher Test Efficiency
R&D Validation
Quality Control
Compare cable designs, materials, connectors and test conditions.
Test multiple production samples efficiently and consistently.
Supplier Comparison
Reliability Testing
Compare cable assemblies from different suppliers under the same conditions.
Collect flex-life and electrical failure data across multiple specimens.
Six Stations. More Test Data. Less Waiting.
Run multiple specimens in parallel instead of testing cables one by one—helping laboratoriesincrease throughput while maintaining controlled and repeatable test conditions.
Programmable Cable Flex Test Conditions
Different cables require different flex test conditions. The RS-8116-6B allows operators to configure the test according to the specimen, test method, and required failure criteria.

Cable Flex Testing for Different Reliability Requirements
Cable bending requirements vary significantly depending on the product.
A thin earphone cable and a multi-core industrial signal cable may require completely different:
Fixture configurations
Bending angles
Applied loads
Test speeds
Cycle counts
Electrical failure criteria
For this reason, cable flex testing equipment should be configured around the actual cable construction and test objective, rather than selected by cycle count alone.
Where an industry standard, customer specification, or internal QC procedure is required, ITM-LAB can configure the test setup according to the applicable test conditions.
