Molex recently added three new terminals to the Mini50 sealed connector after the release of the popular Mini50 wire-to-board connector system. These new types of terminals, called TAK50 terminals, CTX50 unsealed gold-plated terminals, and CTX50 sealed terminals, enable vehicle manufacturers to take advantage of the miniaturized interconnect system in both in-vehicle (unsealed) and off-board (sealed) applications. The advantages.

Jeremy Stout, product manager at Molex Group, said: “In terms of in-vehicle infotainment systems and security, manufacturers are continually adding more and more electronic functions to their vehicles. These additional features have prompted Molex to expand its development and save space. In particular, the use of sealed products allows manufacturers of equipment to now take advantage of the compact form factor to achieve an ever-increasing number of external functions that are exactly what their customers demand."
The new Mini50 sealed connector has a rounded shape for easy through-hole wiring routing and is pre-assembled with vertical independent secondary locking (ISL) at the factory, thus reducing the number of individual components. The 0.5mm, automotive-approved Mini50 connector system is approximately 50% smaller than the USCAR 0.64mm interface. Due to the increased number of on-board electronic components and the limitations of the installation space, automotive manufacturers can continue to improve the size of smaller components. demand. The new model also reduces the overall weight of the harness and allows the wire harness industry customers to crimp and process smaller wire gauge wires than the traditional 0.64 mm terminal system.
Molex's new TAK50 terminals are ideal for applications such as in-vehicle infotainment systems and body-controlled lighting modules, with a dual beam design that is compatible with AK blades and cavities. The TAK50 terminal has been environmentally tested and has been tested to meet the GTM3191 (2012) rated temperature of 85oC to 105oC and meets the LV214 (2010) 105oC and 130oC temperature requirements. Cables from 0.13 mm2 to 0.35 mm2 can be used. .
In terms of the meshing force and separation force of the contacts, the crimping interface and the rated current, the TAK50 terminal performs very well compared with the equivalent competing products. This comes from the plug-in function, which can improve the connection accuracy. Prevent breakage. This new product variant can also be used in various areas of the vehicle that require interconnect systems to withstand high levels of vibration.
The CTX50 unsealed female connector is now available in a gold-plated version for low current, high security, high insertion times. It is also ideal for deployment in corrosive environments. The CTX50 gold-plated terminal can be used with cables from 0.13 mm2 to 0.35 mm2. Compared with 0.64 mm2, it has advantages in weight and space, better conductivity, lower insertion force and higher resistance to oxidation. Receptive.
Molex has also developed a sealed product variant called the CTA50 hermetic terminal, the IP68 grade version does not include an optional back shell, and the IP69 grade version includes an optional back shell for use in electronic systems outside the vehicle. Tolerant to moisture. This new terminal is available in tin or silver plated options and is available in 0.95 to 1.4 mm2 diameter cables. The polarity of the cable can be achieved by the shape of the terminal to ensure the integrity of the seal, while the manhole and/or probe hole are significantly different from the mating pin hole, minimizing the risk of accidental insertion.
