High Durability with Terminal Protection Assurance (TPA) Technology Utilizing Terminal Protection Assurance(TPA) Technology, STC manufactures Molex Mini-Fit 4.2mm with enhancements in its connector housing and contact design to help prevent connection failure. TPA designs offer overlooked connection solutions by providing locking redundancy. This promotes a durable connector design in which terminals can be inserted properly without degradation from unnecessarily exhausting them with thousands of insertions. Equipped with Reduced Mating Force (RMF) Solutions Like Molex Micro-Fit, the MIni-Fit Jr is equipped with RMF solutions for lower friction solution between the contacts of the device and the socket, making insertion and removal of the device easier, while at the same time eliminating the need for complex mechanisms such as in ZIF sockets. Designed for Blind-Mating Applications
