KK® 254 Connector System
Ideal for board-to-board and wire-to-board low-power and signal applications, KK® 254 connectors provide a flexible design and cost-saving solutions for a variety of applications. Signal application KK® 254 connectors are ideal for use in industries such as automotive, medical and consumer, delivering up to 5.0A and 250V per circuit in a 2.54mm centerline pitch. Dual-cantilever terminals offer a square-post contact area that interfaces with the male pin header through a spring-like contact. Available in 22 to 30 AWG wire, an optional box-style dual-cantilevered terminal is optimal for high-vibration applications.

Headers are available in single-row, unshrouded, through-hole PCB termination styles in solid and breakaway varieties. A friction lock is available for a more secure mating interface. KK 254 PCB receptacles are available in right-angle, top-entry and board-through configurations. Housings have built-in polarization features and are available in UL 94V-2 and UL 94V-0 nylons.
