Molex Mini Fit Jr Connectors & More

A popular mini-pin connector, the Molex Mini Fit Jr. Connector, is designed for high current, high density applications that require design flexibility for both wire-to-wire and wire-to-board configurations. Mini Fit Jr. Connectors are ideal for power applications up to 9 amps per circuit, and feature fully isolated terminals, positive housing locks, low engagement forces, and polarized housings. They are UL recognized and CSA approved. All components are lead-free and RoHS (Restriction of Hazardous Substances) compliant. The receptacle housing can be connected with a variety of plug options, including panel mount and free hanging plugs, or vertical and right angle headers.

The Molex Mini-Fit Jr. mini-pin connectors are available in either single-row or dual-row 2-to-24-pin options. They feature multiple plating and material selections, making them the appropriate choice for a wide variety of consumer and industrial applications.

In addition to the Mini Fit Jr. mini-pin connectors, Waytek carries thousands of other innovative and reliable electrical parts from Molex. For more information on any of Waytek’s Molex interconnect products, contact the Waytek sales department at 800-328-2724 or sales@waytekwire.com.
