M12 connectors for e-cigarette testing fixtures, making the equipment look more professional.
A Shenzhen testing equipment company makes test fixtures and automated inspection lines for e-cigarette manufacturers. Their fixtures require frequent connect/disconnect cycles during product testing. Banana plugs and jacks originally used showed increasing contact resistance over time, causing unstable test readings.
We recommended M12 A-coded 4-pin connectors for the fixture signal interfaces. M12 connectors are rated for 500+ mating cycles — far exceeding banana plugs. The threaded locking ensures consistent contact resistance every time, giving repeatable test results. The metal housing also elevated the fixture's overall build quality.
Test data drift was eliminated after the switch. The equipment also looked much more professional — the customer said it helped win bids. Each inspection line now uses 20-30 M12 ports, with annual consumption of about 5,000 units.
