JST’s LEX Series for LED Applications
JST’s LEX Series for LED applications is a line of subminiature, crimp-style, wire-to-board connectors.
JST‘s LEX Series wire-to-board, crimp-style, disconnectable connectors offer subminiature size and reliable contact construction for high-density applications. These 2.5mm (.098″) pitch, bottom-entry, SMT connectors are polarized and have a positive locking feature when mating to headers, including an audible click when mated. Ideally suited for low-current, low-voltage conditions, such as LED light applications, they are designed for maximum PCB flexibility with a mated height of only 3.0mm (.118″) and will not interfere with the luminescence angle of the PCB-mounted LED dies.
The LEX crimp style connector series is available in two and four circuits with a 3.0A (AC/DC) rating using a 22AWG wire at 300V AC/DC. Wire sizes up to 30AWG are accommodated. Temperature range is -55°C to +105°C, including temperature rise in applying electrical current. Headers are molded from halogen-free, RoHS-compliant 94V-0 resin and feature insertion guides for easy and secure mating.
The LEX Series uses the SFH contacts, which are designed to accommodate a wire range of 22AWG to 30AWG and are tin-plated over a phosphor-bronze base material. The box construction ensures stable contact performance, redundant contact points, positive electrical contact, and low contact resistance at all times when subjected to vibration and distortion.
Contacts are offered on standard size reels for semi-automatic or fully automatic application tooling. SMT headers are provided on embossed tape for automatic insertion equipment.
