SOLUTIONS
A meter or IoT terminal is provisioned at the factory and then lives in the field for years. Its connectors are mated a handful of times — what matters is contact stability over temperature and time, and a supplier that still stocks the part when a service batch is needed a decade later.
Cellular uplink: nano SIM sockets in 1.25mm to 1.37mm profiles with card-detect options. Local logging: microSD (T-Flash) connectors — the microSD guide covers durability classes. Tamper and cover detection: detection switches with operating lives from 10,000 to 1,000,000 cycles and low-profile options from 0.55mm. Module-to-board stacking: BTB connectors in 0.4mm to 1.27mm pitches (see the BTB guide).
Parts are RoHS compliant with UL94V-0 rated housings on listed models, and every published specification value carries its source engineering drawing — your hardware team verifies against the original drawing before layout.
Send the card types, detection points and stack heights on your terminal to service@kingconn.com.tw — the Taoyuan R&D team responds with drawings and samples.
