JST LEH Series for LED Applications

By News Release | May 19, 2014

JST LEH Series crimp-style, wire-to-board connectors provide a space-saving low profile for LED applications.

JST LEH Series for LED ApplicationsThe new LEH Series wire-to-board, crimp-style, disconnectable connector from JST offers engineers design flexibility with its low profile and space-saving design. The subminiature connector features a 1.8mm (.071”) pitch, a side-entry mating height of only 3.0mm (.118”), a secure friction locking mechanism, and a mechanism to prevent improper insertion. Ideal for low-current, low-voltage conditions, the LEH Series is designed for LED light applications.

The low profile of the connector does not interfere with the luminescence angle of the PCB-mounted LED dies. These SMT connectors are polarized and have a friction locking feature when mated to the cable housing that includes an audible click when mated. The housing is notched on one side for ease of locating pin 1 position. The LEH crimp-style connector series is available in two circuits with a 3.0A (AC/DC) rating using a 22 AWG wire at 300V (AC/DC). Temperature range is -550°C to +1050°C including temperature rise in applying electrical current.

Available in side-entry (right-angle) -only mounting configuration, the fully shrouded headers are molded from halogen-free, RoHS-compliant 94V-0 resin and feature insertion guides for easy and secure mating. The LEH Series contacts accommodate wire sizes 22 to 26 AWG and are made of tin-plated, copper alloy base material. The box construction ensures stable contact performance, redundant contact points, positive electrical connection, and low contact resistance at all times, even when subjected to vibration and distortion. Contacts are offered on standard size reels for semiautomatic or fully automatic application tooling. SMT headers are provided on embossed tape for automatic insertion equipment.
