Molex adds sealed versions and additional plating options to iMini50 connector system

Molex has added three new terminals plus the Mini50 sealed connector to its range.

Designated as TAK50 terminal, CTX50 unsealed gold terminal, and CTX50 sealed terminal, these new terminals enable vehicle manufacturers to use miniaturised interconnect systems in both interior (unsealed) and exterior (sealed) applications.

The Mini50 sealed connector features a rounded shape for through-hole harness routing and a vertical independent secondary lock (ISL) that is shipped pre-assembled, reducing the number of individual components. Approximately 50% smaller than the USCAR 0.64mm interfaces, the 0.5mm automotive approved Mini50 range addresses growing demand from vehicle manufacturers for smaller components solutions due to the growth in on board electronics and installation space restrictions. The new models also provide reduced overall harness weight savings by allowing wire-harness customers to crimp and process smaller wire gauges versus traditional 0.64mm terminal systems.

The TAK50 terminal features a two beam design and is AK blade and cavity compatible. Environmentally tested/ validated to GMW3191 (2012) with temperature ratings of 85ºC to 105ºC and LV214 (2010) featuring 105ºC and 130ºC, the TAK50 terminal accepts 0.13mm² to 0.35mm² cables.

The TAK50 terminal also benefits from a pin alignment feature for connection accuracy and an anti-stub feature.The new variant can also be used in areas around the vehicle that require interconnects that are able to cope with high vibration.

The CTX50 unsealed female terminals are now available with a gold option for low current, safety, and high mating cycle applications and are suitable for deployment in corrosive environments. Accepting cable sizes of 0.13mm² to 0.35mm², CTX50 gold terminals, as compared to 0.64mm alternatives, deliver the benefit of weight and space savings,better conductivity, lower insertion force, and are more resistant to oxidisation.

Molex has also developed a sealed variant, namely the CTX50 sealed, IP68 without optional back shell and IP69 with optional back shell, for use in exterior vehicle electronic systems that are liable to encounter moisture. Available with either tin or silver plating, the new terminal accepts 0.95 to 1.4mm² diameter cables. The polarisation of the cable is achieved by terminal shape, thus maintaining seal integrity and the service/ probe holes are distinct from the mating pin hole to ensure the risk of accidental insertion is minimised.
