This compact wire-to-board connector is designed for high-density internal wiring applications in consumer electronics and portable devices. The SR series features a secure lock mechanism that provides an audible click upon mating, ensuring reliable connection. The fully shrouded 4-wall header design protects the contacts from damage and prevents misalignment during mating. With a 1A current rating and 50V voltage rating, this connector is suitable for low-power signal applications. The (LF)(SN) designation indicates lead-free compliance with tin plating on the contacts. The mated stacking height is 4.9mm, enabling low-profile board-to-cable connections in space-constrained designs.","working_principle":"The BM02B-SRSS-TBT(LF)(SN) operates as a disconnectable wire-to-board connector system consisting of a PCB-mount header and a crimp-style wire housing. The header features square-pin contacts made of copper alloy with tin plating, soldered directly to the PCB via surface-mount technology. The mating housing (NSR-02V-S series) uses phosphor bronze crimp contacts that are inserted into the housing and mate with the header pins. The secure lock mechanism uses a spring-loaded latch on the housing that engages with a corresponding feature on the header, providing both retention force and tactile feedback during mating. The 1.0mm pitch allows for compact routing of signal traces on the PCB with minimum trace width and spacing of 0.1mm typical. The tin-plated contacts provide reliable solder joints during reflow and maintain low contact resistance (initial 20m\u03a9 max) throughout the connector's operating life.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Circuit 1<\/td><td>Signal<\/td><td>Signal contact position 1<\/td><\/tr><tr><td>2<\/td><td>Circuit 2<\/td><td>Signal<\/td><td>Signal contact position 2<\/td><\/tr><\/table>","application_scenarios":"<ul><li><strong>Consumer Electronics:<\/strong> Internal signal wiring for smartphones, tablets, and wearable devices where 1.0mm pitch saves PCB area.<\/li><li><strong>Display Modules:<\/strong> LCD\/LED panel signal connections with secure lock preventing disconnection from vibration.<\/li><li><strong>Sensor Interfaces:<\/strong> Low-power sensor module connections in IoT devices with 1A current rating sufficient for most sensor applications.<\/li><li><strong>Portable Devices:<\/strong> Battery-powered equipment where compact size and reliable mating are critical for miniaturized designs.<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Pitch<\/th><th>Circuits<\/th><th>Notes<\/th><\/tr><tr><td>JST<\/td><td>SM02B-SRSS-TB(LF)(SN)<\/td><td>1.0mm<\/td><td>2<\/td><td>Side-entry variant<\/td><\/tr><tr><td>JST<\/td><td>BM03B-SRSS-TBT(LF)(SN)<\/td><td>1.0mm<\/td><td>3<\/td><td>3-circuit version<\/td><\/tr><tr><td>Hirose<\/td><td>DF11-2DP-2DS(24)<\/td><td>2.0mm<\/td><td>2<\/td><td>2mm pitch alternative<\/td><\/tr><tr><td>Molex<\/td><td>51021-0200<\/td><td>1.25mm<\/td><td>2<\/td><td>PicoBlade alternative<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/10266","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=10266"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/10266\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=10266"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=10266"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=10266"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=10266"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
