[Industry 10] Testing cables and wire harnesses for the facility equipment industry

Concept of Testing & Inspection

Testing cables and wire harnesses for the facility equipment industry

1. Overview

Machines that make things and equipment that help save labor. They are evolving day by day to realize new technologies. High-quality wire harnesses are essential for high-precision equipment. Examples of equipment: Power distribution boards/control panels/robots/elevators/semiconductor manufacturing equipment, etc.

2. Features and testing of control panel/distribution panel wiring harnesses

  • ・Control panels and switchboards are often manufactured by wiring one circuit in the panel at a time.
  • ・If the terminal is a connector, inspection is easy. However, if the terminals include round terminals, some effort is required to check for continuity.
  • ・Wiring, resistance, and withstand voltage testing are conducted.
  • ・The number of test points requires about 1,000 points.
  • ・Products that support wiring work by confirming continuity with a finger touch are also popular.

3. Features and testing of wiring harnesses for robots

  • ・Need for harnesses that can withstand complex movements and bend.
  • ・Twisted pair cables are used to improve noise immunity and communication distance. split pair will cause signal quality degradation, not to mention the lack of expected effect.
  • ・In addition to wiring and resistance testing, split pair detection can also be performed by the harness tester to ensure high-quality cables.

4.Features and testing of wiring harnesses for elevators

  • ・Elevator harnesses are long, multi-pointed, and complex.
  • ・Wiring and resistance testing are conducted
  • ・Progressive type testing is also effective in improving efficiency. Harness testing equipment can be used for manufacturing instructions and housing.
  • ・If it is a long cable, the continuity judgment must be delayed and judged correctly.

5. Features and testing of wiring harnesses for semiconductor manufacturing equipment

  • ・Huge harnesses are used in semiconductor manufacturing equipment. Thousands of test points are needed to inspect them.
  • ・All five electrical testing (wiring, resistance, withstand voltage, insulation, and momentary disconnection) of harnesses are performed.
  • ・High-voltage multi-point testers (over 1024 points) are available on custom-order.
