APPLICATION SPECIFICATION
MX150™ RECEPTACLE CRIMP TERMINAL
1.0 SCOPE
This specification details the crimping information and common practices for general crimps for the Molex MX150 receptacle terminal per sales drawing SD-33012-002. Please refer to the sales drawing for additional part information. The information in this document is for reference and benchmark purposes only. Based on theguidelines of USCAR-21 the user is responsible for validating crimp performance based on tooling, equipment and wire that is being used. All measurements are noted in millimeters unless otherwise specified.

BELLMOUTH (FLARE) 5

The flare that is formed on the edge of the conductor crimp acts as a funnel for the wire strands. This funnel reduces the possibility that a sharp edge on the conductor crimp will cut or nick the wirestrands.

Figure 3

CONDUCTOR BRUSH 8
The conductor brush is made up of the wire strands that extend past the conductor crimp on the contact side of the terminal. This helps ensure that mechanical compression occurs over the full length of the conductor crimp. The conductor brush should not extend into the contact area or above the conductor crimp height. CAUTION: Excessive conductor brushextended above the transition/crimp can cause connector water leak by compromising the glands of the matte seal.

Good Crimp

CONDUCTOR CRIMP
This is the metallurgical compression of a terminal around the wire's conductor. This connection creates a common electrical path with low resistance and highcurrent carrying capabilities.

CONDUCTOR CRIMP HEIGHT 10
The conductor crimp height is measured from the top surface of the formed crimp to the bottom most radial surface. Do not include the extrusion points in this measurement. Measuring crimp height is a quick, nondestructive way to help ensure the correct metallurgical compression of a terminal around the wire's conductor and is anexcellent attribute for process control. The crimp height specification is typically set as a balance between electrical and mechanical performance over the complete range of wire stranding and coatings, and terminal materials and plating. Although it is possible to optimize a crimp height to individual wire strandings and terminal plating, one crimp height specification is normally created.
