Connectors for Rugged & Industrial Embedded Systems

Why industrial designs pick differently

A rugged or industrial PC is serviced in the field for years: storage cards get swapped, SIMs get re-provisioned, and the connector — not the card — sets the service life. The selection logic below reflects what industrial-PC and instrument makers actually ask us for.

Removable storage: durability class first

KINGCONN microSD sockets are rated at 5,000 or 10,000 insertion cycles. Field-serviceable storage earns the 10,000-cycle class; models with a card-detect switch let firmware tell "no card" from "card failed" — the difference between a truck roll and a remote diagnosis. See the microSD selection guide.

Expansion: M.2 and legacy slots

The catalog covers M.2, Mini PCI and DIMM slots for compute and radio modules, alongside Nano/Micro/Mini SIM sockets for cellular-connected equipment.

Module-to-carrier: fine-pitch board-to-board

Carrier-plus-module architectures ride on BTB pairs from 0.4mm pitch (space-first) to 1.27mm (alignment-first) with mated heights from 0.8mm up to 15.0mm spacer class — details in the BTB selection guide.

Supply and verification, the industrial way

Every published specification value cites its source engineering drawing on the part page, so your hardware team verifies against the original before layout. KINGCONN designs and tools in Taoyuan, Taiwan (ISO 9001:2015) and supports ODM customization — including long-life variants of catalog parts.
