JST Compact, Waterproof Wire-to-Wire and Wire-to-Board Connectors
The new JST compact, waterproof wire-to-wire and wire-to-board connectors are cost-effective solutions for underwater applications.
The new JWPS Series wire-to-board and wire-to-wire connectors from JST Corporation offers engineers design flexibility with a small form factor solution for a waterproof IP67-rated product for extreme moisture or submersion applications. They are ideal for automotive, appliance, photovoltaic, underwater cameras, and other related consumer and commercial devices.
The unique construction includes a seal ring that protects from moisture, dirt, scratches, and cracks by completely sealing at the mating site that is contained in the header or tab housing, depending on which series is being used. In addition, a solid rubber seal is used for wire-side sealing that allows for its compact size. All seals are pre-assembled, eliminating the need for additional handling on the manufacturing floor.
The unique contact-locking feature is internal to the housing, thereby eliminating contact back-out and damage through handling external locking lances. The contact system has a double-spring construction that ensures superior contact force. To facilitate proper mating, connectors offer keying and color coding. In addition to the keying and color coding, the receptacle housing features a positive, squeeze-to-release locking system to prevent accidental unmating.
The connectors are available for two to four circuits on a 2.0mm (.079”) pitch (contact to contact) and 4.0mm (.158”) pitch row-to-row spacing for double-row versions. The overall size when mated is just 30.2mm (1.189”) for the wire-to-wire and just 21.0mm (.827”) for the wire-to-board version. These waterproof connectors deliver a cost-effective solution by utilizing a copper alloy tin-plated tab contact and a copper alloy tin-plated receptacle contact. Contacts are rated at 6A (AC/DC), 300V (AC/DC). Temperature range is -55ºC to +85ºC including temperature rise in applying electrical current. Applicable wires are AWG #18-22. Shrouded headers on the wire-to-board connector utilize a copper alloy tin-plated contact and are only available in side entry.
