Working principle

When the QFS-026-01-SL-D-RA-PC4-K female rectangular connectors are mated, the contact system inside the connector engages with the contact system of the mating connector. This allows electrical signals to pass between the two connectors. The polarized key and the grounding clip prevent the connectors from being mated incorrectly and ensure that the two connectors continue to hold the connection. The pin contacts are designed to provide efficient electrical connection and the robust multi-point contact system makes sure that the connector is stable and reliable. The self-cleaning contact system prevents the contact system from degrading over time due to dust or dirt.
