Addition of 2 circuit-size SMT headers and receptacles Delivers the only two-circuit connector with a

0.50mm terminal interface in the industry. Tested to

full USCAR specifications. Enhances design flexibility

Designed and tested to USCAR 050 specifications Industry’s only interface that meets USCAR 050

specifications. Offers from 4 to 24 circuits. Larger

circuit versions also comply with USCAR specifications

50% smaller than USCAR 0.64mm unsealed interfaces Minimizes PCB footprint for design flexibility and

space saving

Independent secondary lock (ISL) terminal-retention feature Secures terminal inside the housing; one piece

design for applied cost savings

Orientation features molded into the header Provides wire-routing and module-design flexibility

for both vertical and right-angle connectors. Retains

the header to the PCB during the soldering process

Board alignment and retention features Simplifies header placement on the PCB and retains

the header to the PCB during soldering operation(s).

Protects adhesive joints during connector mating

and unmating

High-temperature thermoplastic housings Withstands infrared (IR) and wave lead-free solder

processing per ES-40000-5013 Molex specification,

up to a maximum temperature of +260°C

Gold plating option Better conductivity and corrosion resistance and

lower insertion force than standard tin plating.

Three polarization options Enables limited customization and enforces like-to-

like mating via three discrete mechanical, visual, and

colored polarizations

CTX50 terminal wire grip design Offers harness manufacturers the ability to reduce

wire gauge sizes while maintaining retention strength

Connector position assurance (CPA) feature available An optional mating assurance feedback device that

prevents accidental un-mating

Mini50 Unsealed

Connector System

Delivering 50% space savings over traditional USCAR

0.64mm connectors with smaller terminals to fit more

signals into vehicle interiors, the Mini50 Unsealed

Connector System is approved as the industry’s only

USCAR 050 interface
