Cable Swing & Flex Durability Testing for Wire Harness Reliability
Cable assemblies and connectors are frequently subjected to repeated bending, twisting, and mechanical movement during real-world operation. Over time, these stresses can cause conductor fatigue, insulation damage, or connection failure. To evaluate the durability of cables and connectors under repeated movement, our laboratory uses the JTM-WC1811A Cable Swing Tester, manufactured by JTM Technology Co., Ltd. This testing equipment simulates long-term mechanical stress by repeatedly swinging or bending cable assemblies under controlled conditions. By performing controlled swing cycle testing, we can verify the flexibility, durability, and strain relief performance of cable assemblies used in demanding applications.
Equipment Overview
The JTM-WC1811A swing tester is designed to perform cyclic bending and swing motion testing on cables, connectors, and wire harness assemblies. The machine operates by repeatedly moving the cable through a defined angle while the connector or cable end is fixed. This motion simulates real-world usage conditions such as connector movement during device operation, cable bending at strain relief points, and repeated flexing in moving equipment.
Multiple testing stations allow several samples to be tested simultaneously, improving efficiency during reliability verification.

The multi-station configuration allows testing of several cable assemblies at the same time, enabling efficient reliability evaluation during product validation.
The swing tester is used to evaluate the durability of cables and connectors when exposed to repeated mechanical movement.
Typical testing applications include:
• Cable bending durability testing
• Connector strain relief reliability testing
• Flex life testing for cable assemblies
• Repeated motion durability verification
• Mechanical fatigue testing of wires and connectors
During testing, the machine repeatedly bends the cable through a defined angle while monitoring electrical continuity or failure conditions. Many electronic products involve constant cable movement during operation. Examples include robotics and automation equipment, industrial control systems, consumer electronics, and automotive harness applications. Without proper durability testing, repeated cable bending can lead to conductor fatigue breakage, insulation cracking, intermittent electrical connection, and connector strain relief failure. Cable swing testing helps verify that cable assemblies can withstand long-term mechanical stress without performance degradation.
Flex durability testing is commonly used during product validation and reliability evaluation for cable assemblies. The testing results help confirm that cable designs meet the mechanical endurance requirements defined by product specifications and industry practices. By performing controlled swing testing in our laboratory, we can evaluate the durability of cables before they are deployed in real-world applications.
At Everbiz Industrial, durability verification is an important part of our quality assurance process. Using equipment such as the JTM-WC1811A Cable Swing Tester, we can simulate repeated cable movement to ensure that our wire harness assemblies maintain reliable electrical performance over extended use. This capability helps ensure that our products deliver stable mechanical performance, reliable electrical connection, and long service life in demanding operating environments.
