MOLEX / BRAD Mini-Fit Jr. Plug Housing, 4.2mm Pitch, 4-Way, 2mm Depth

The MOLEX / BRAD Mini-Fit Jr. Plug Housing is a high-quality, single-row connector housing designed for reliable electrical connections. It features a 4.2mm pitch spacing and provides four positions, making it an ideal solution for compact wiring applications where space is at a premium.

This plug housing incorporates several key design features to ensure a secure and foolproof connection. It boasts a positive locking mechanism, which provides an audible click and tactile feel to confirm a proper mate, preventing accidental disconnection. The housing is also scoop-proof, meaning it is designed to prevent incorrect or damaging insertion of the mating connector, protecting the delicate pins and terminals from harm.

Furthermore, the connector utilises a polarized mating geometry. This physical keying system ensures that the plug can only be inserted into its corresponding receptacle in the correct orientation, eliminating the risk of misalignment and potential short circuits. This plug is compatible with standard Mini-Fit and Mini-Fit Plus crimp terminals, offering flexibility in your assembly process.

Specifically designed as part of the Mini-Fit Jr. 5559 series, this plug housing is intended for use with MOLEX / BRAD Mini-Fit Jr. 5558, 30490, and Mini-Fit Plus 46012 series pin contacts. Its compact dimensions of 22mm in width, 33mm in height, and a slender 2mm depth allow it to fit into tight spaces on PCBs or within electronic enclosures, making it a versatile choice for a wide range of electronic devices and industrial controls.
