To introduce the new LEX wire-to-board,
crimp style connector series for LED applications.

LEX Connector
Ideally suited for LED light applications, where a wire-to-board connector that is sub-miniature in size and offers
engineers design flexibility is required. The low profile of the connector does not interfere with the luminescence
angle of the pcb mounted LED dies.
The LEX Series wire-to-board, crimp-style connector is on a 2.5mm (.098”) pitch, and is molded in a RoHS compliant
94V0 (SMT headers) resin. The LEX Series incorporates both polarization and friction locking features.
Rated at 3A AC/DC (using 22 AWG) at 300VAC, these low profile connectors have a side-entry, mated height of only
3.0mm (.118”). The series has an operating temperature range of -55 to +105 C including temperature rise when
applying an electrical current. The series is offered in a 2 & 4 circuit size.

3. LEX Connector crimp style wire-to-board contact

Standard Contact
The LEX Series uses the SFH contacts, which are designed to accommodate a wire range of 22AWG to 30AWG are tinplated 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 even when subjected to vibration and
distortion.
The suggested wire strip length is 1.7mm. Crimp heights vary by wire size - 0.56mm (30 AWG) to 0.78mm (22 AWG).

4. LEX Connector crimp style wire-to-board housing

LEXR-02V-S(HF)
LEXR-04V-S(HF)
Molded in a 94V-0 rated, Halogen free, resin, the polarized LEX Series housings incorporate
a positive locking feature preventing accidental disconnection due to routing of wires or
vibration. Available in 2 circuits only. The positive lock provides an audible click and is felt
when mating the housing assembly with the mating header. The housing is notched on one
side for ease of locating the pin 1 position.

5. LEX Connector SMT headers

EM02B-LEXSS-TF(HF)
EM04B-LEXSS-TF(HF)
Bottom-entry
Available in bottom-entry (right angle) only mounting configuration, the RoHS compliant, Halogen free,
fully shrouded headers are 94V-0 rated and feature insertion guides for easy and secure insertion of the
mating LEX housings. The copper alloy posts are reflow treated tin-plating over copper-underplating and
are designed to prevent accidental removal of the pins that might result from distorted mating. Copper
alloy, copper-underplated, tin-plated reinforcement tabs offer strength and stability to the mounted
headers. The SMT headers are packaged in embossed tape for automated placement equipment.
