This document describes the features and characteristics of a connector called CCM02 MK II. The connector has 8 contacts, a mechanical life of 500,000 cycles, a card insertion force of 10N maximum, and a card extraction force of 1N minimum/10N maximum. The connector features a card detection switch and has a dust and water resistance rating of IP54. The connector is suitable for a temperature range of -40°C to +85°C. The product has good electrical insulation performance and current conduction performance.
The CCM02 MK II connector is designed for high‑usage applications where card lifespan is critical. It offers 500,000 insertion cycles, a positive insertion indication, and a compact, low‑profile design that saves PCB space. The connector includes an integrated card‑end‑travel switch sealed against dust and an in‑lay gold alloy contact finish for extended life.
Technical data cover mechanical dimensions, contact and switch electrical characteristics, environmental limits, and ordering codes for both through‑hole and SMT versions. Detailed drawings and PCB layout guidance are provided for proper implementation.
