Modular Spring Contacts

Bourns modular contacts are off-the-shelf spring interconnect devices offering a low-profile design with proven reliability to 50,000 mated cycles. They can be used as board-to-battery, board-to-device, and board-to-board connectors anywhere a rechargeable battery pack is required, including tablets, laptops, medical equipment (low/medium risk), and test equipment. Because they can be used as either compression or sliding interconnects, they can function as connectors for many other non-battery-related applications. Offered in three pitch sizes and capable of end-to-end stacking, the Bourns modular contact products provide the options users need for a solution to a design.

The 70AA, 70AB, 70AD, 75AB, 76AA, and 78AD series are engineered to provide excellent performance for demanding industrial, mobility, medical*, and consumer applications, including but not limited to industrial automation, precision instrumentation, and advanced docking applications where high reliability is essential.

Bourns high-power modular contacts offer a symmetrical pad layout, auto-centering, end-to-end stackability, pick-and-place compatibility, compact footprint, and current ratings of up to 8 A per contact, all with an extended life of 50,000 cycles minimum. These features enhance durability and flexibility, benefiting user design outcomes. Their robust construction ensures consistent connectivity under demanding conditions.
