BM46 Series, Small 2.0 mm width, Pitch 0.35 mm, Stacking height 0.6 mm, Space-saving Multi-RF, Board-to-Board Connector

BM46 Series

HIROSE Electric Co. Ltd., a world-class manufacturer of innovative connector solutions has released its BM46 Board-to-Board connectors as a solution for customers seeking high performance, compact size, and retention security.

Recognized as a 2020 CES honouree award, the BM46 connector range is one of the smallest connectors in its class. The pitch is only 0.35 mm, with a narrow width of 2.0 mm. The ultra-low parallel stack height is 0.6 mm, with a contact design ideal for both high speed digital transmission and RF signal.

Featuring a 0.3 A current rating, small footprint and strong snap retention, Hirose has developed a comprehensive terminal solution for design engineers working on space-constrained applications. Hence providing more possibilities for additional components on an PCB and increasing functionality.

The design of the centre shield for noise prevention between opposing rows enables flexibility in the pin assignment. In addition, it’s metal-to-metal contact and guide design reduces the risk of damage to the connector if misaligned during mating. Moreover, it has a feature to mate with a positive click and a tactile sensation to confirm correct and complete mating.

Hirose BM46 connectors are suitable for a variety of applications utilizing 5G or IoT (Internet of Things) technologies such as smart phones, notebooks, tablet pcs, wearable devices, mobile routers, Wi-Fi access points and many others.
