SOLUTIONS
On a payment terminal or kiosk, card interfaces are actuated by the public, every day, for years. That pushes duty requirements an order above typical board connectors — and it is why listed KINGCONN smart card connectors carry a 100,000-cycle minimum rating (see the smart card guide).
Transaction logging and configuration ride on SD sockets with 10,000-cycle classes; cover and paper-door detection uses switches rated up to 1,000,000 operations; cellular-connected terminals add a nano SIM socket, and USB Type-A serves as the service port.
Listed models are RoHS compliant with UL94V-0 housings, and every published specification value carries its source engineering drawing number for pre-layout verification.
Send the card interfaces, actuation counts and panel constraints of your terminal to service@kingconn.com.tw — drawings and samples from the Taoyuan R&D team.
