The finger touch sensor NMT64B is an optional product for harness testers that enables continuity testing by touching the conductor of a cable with your finger. It utilizes the induced current received by the human body to confirm the continuity of the conductor touched by the finger. It can be connected to all harness testers sold by Nack Corporation that feature a search function. Currently, in the inspection field of wire harnesses, testing of one-side cut cables (one side unprocessed and untreated) is difficult with probes, posing challenges for continuity testing operations. This product allows for continuity testing simply by touching the end of a one-side cut cable with your finger, significantly improving work efficiency and greatly reducing inspection time. In addition to one-side cut cables, it can also be used for various applications such as navigation during connector housing and wiring work in distribution boards.

Unexplained defects may be due to momentary disconnections? Implementing momentary disconnection testing to ensure higher quality. This is a very troubling issue not only for those conducting harness inspections but also for connector manufacturers and set manufacturers. One of the solutions that has been increasingly useful is momentary disconnection testing. By introducing momentary disconnection testing in connector inspections and final inspections after harness cable creation, we can check whether the physical contact condition of the connector mating part is reliable. This helps ensure higher quality and supports the achievement of zero defects. Compact and space-saving! High-level momentary disconnection testing even on your desk! The NMM01A is the most compact inspection device for momentary disconnection testing. Momentary disconnection testing is gaining attention in various fields, including automotive and aerospace.
