The XH connector was developed based on the high reliability and versatility of our NH series connectors. The connector is very small with a mounting height of 9.8mm (.386"). Yet it meets the needs for high-density mounting and miniaturization of electronic equipment, including VCRs, radio-cassette players, and car stereo systems Original folded beam contact The protected, folded beam contact in this connector provides high contact pressure with an over-stress stop feature. This ensures dependable continuity when used with low voltage, low current carrying circuits (dry circuits). The wire crimp section is mechanically decoupled from the post insertion section which, in turn, prevents the mating area from being adversely affected by crimping. Box-shaped shrouded header The four-sided, box-shaped shroud prevents the receptacle from being misinserted or pried during insertion and removal. The shroud also prevents foreign matter from reaching the posts and resists contact deformation due to handling and shipping. Furthermore, a serrated, oversized square post is pressure-fit into each square hole to completely protect the post against heat and to prevent flux from entering during dip soldering. Header with a boss This header has a boss (projection) on the bottom of the housing to prevent improper insertion in printed circuit boards. Whisker prevention The contact is treated with a reflow process and the square post is copper-undercoated and tin/lead-plated to prevent whiskers from being generated. Interchangeability This header is interchangeable with those of 2.5mm (.098") pitch insulation displacement NR and NRD connectors and board-to-board JQ connectors. Conforming to the HA terminal The 4-circuit XH connector conforms to the HA terminal specified in JEM 1427 (Japanese Electric Machine Industry Association Standards).
