DESCRIPTION
I/O CONNECTORS
Latch-N-Lok™is a versatile cable-to-equipment connector
interface designed for end user convenience and durability.
The Latch-N-Lok™family includes PCB receptacles and
cable plug kits to connect signals or power. The
connection system provides integral shielding and
grounding for controlling EMI/ESD.
FEATURES & BENEFITS
Quick connect system provides positive latching with an
audible “click.”
Supports high speed, serial data transmission
High reliability design features “FCI Mini PV™” receptacle
contacts mating to phosphor bronze .025”sq pin contacts
in single and double row 0.100” pitch configurations.
Polarized housings prevent mis-mating; Keying options
prevent the mating of incorrect cables.
Choice of four popular colors: Off-white, Silver Gray, Pebble
Gray and Black.
Easy-to-assemble cable kits provide an over-molded look
without requiring an investment in custom mold tooling
Cable connectors accommodate a wide variety of cable
diameters and wires ranging from 20AWG to 32 AWG
Connector sizes range from 4 to 20 positions
Lead-free, RoHS compatible products satisfy environmental
regulations.
