CUI’s Interconnect Group has released the UJ2W-MIBH-4-SMT, a waterproof micro USB2.0 type-B jack connector which has an IP rating of IPx7, offering protection from liquid and moisture in challenging environments.

Thanks to its copper-alloy contact terminals with 30μinch gold-over-nickel plating and stainless steel shielding, the UJ2W-MIBH-4- SMT offers high durability over a rated lifetime of 10,000 mating cycles. The connector is housed in a surface-mount package with a horizontal orientation. It has a voltage rating of 30V AC, a current rating of 1.8A, and an operating temperature range of -25°C to 85°C. Plastic mounting ears are also included to provide added stability on the board.

Complying with the USB2.0 standard, the UJ2W-MIBH-4-SMT allows for high-speed data and power transmission, making it well-suited for a variety of I/O applications in consumer and portable electronic devices that may be used in outdoor environments.
