EdgeLock Wire-to-Edge-Card Signal Connector

Molex's EdgeLock wire-to-edge-card signal connectors offer space savings and positive locking for secure mating to PCB edge cards. Typically, the header is soldered to the PCB, which adds space and assembly steps. Extra steps are involved if rework is required. EdgeLock is a solution for direct mating to PCB edge-card. At the same time, the latch can be used to release the assembly easily from the PCB.

The demand for positive locking is growing, improving PCB retention forces. Positive locking systems offer strong PCB-to-connector retention. Normal crimp terminals are easily damaged and have short-term electrical performance due to weak reliability. Dual cantilever crimp-terminal designs promote long-term electrical performance and reliability. And polarized crimp terminals ensure correct orientation and insertion into the housing. Some materials cause environmental issues and may not hold up to harsh conditions. The PA46 resin material is low halogen and ideal for high-temperature environments.

The polarization rib on the connector housing prevents mis-mating to the PCB. The EdgeLock connectors are available in 2-, 4-, 6-, and 8-circuits for 1.20 mm or 1.60 mm PCB thickness with a 2.00 mm pitch. They have a durability of maximum 30 cycles, a voltage maximum of 125 V, a current maximum of 3.0 A, an operating temperature of -40°C to +105°C, a dielectric withstanding voltage of 1,000 V, wire AWGs of 22 or 24, and are halogen-free and RoHS compliant.
