SL Modular Connectors

Molex SL (Stackable Linear) Modular Connectors include surface mount headers for low-power and signal wire-to-board and wire-to-wire applications. The comprehensive SL Modular Connector System includes two independent points of contact, a positive lock that secures retention between headers and receptacles, and a 2.54mm pitch. These connectors and assemblies provide ideal wire-to-wire solutions and supports a range of wire-to-board applications. Molex SL Modular Connectors are ideal for HVAC equipment, dental equipment, breathing machines, computer peripherals, and various automotive applications.
