Rutronik flexes its muscles with Molex’s Micro-Fit 3.0 connector system  

The Micro-Fit 3.0 connector system from Molex provides a reliable power supply in a compact design, said Rutronik. It has a wide range of pole numbers and cable lengths for power and signal transmission, a pitch of 3.0 mm and a maximum current carrying capacity of 8.5A. 

The system is now available from Rutronik. Optional features such as contact position assurance (TPA), blind mating capability, and press-fit technology, among others, provide OEMs with the flexibility of design to meet the demands of space-constrained applications, including automotive, consumer, medical, and telecommunications / networking. 

The Micro-Fit 3.0’s fully insulated terminals protect against possible damage to the terminals during handling as well as mating and minimise the risk of short circuits due to debris.

The series consists of connectors designed for hard-to-reach applications, such as slide-in units or fan trays, where connections must be able to be closed and opened without or with limited visual contact. The Micro-Fit BMI (Blind Mate Interface) provides blind-mateable cable-to-cable and cable-to-board connectors, with up to 2.54 mm tolerance to misalignment and self-alignment capability.

A contact position assurance (TPA) feature reduces contact slippage by providing redundant locking. It can only be closed when the contact is correctly positioned. Molex Micro-Fit TPA connectors prevent interference with end products. They are available in single-row with integrated secondary locking and double-row. 

The CPI specification of the Micro-Fit 3.0 connectors includes a spring-loaded press-fit pin interface while retaining all the features of the standard Micro-Fit 3.0 connector. In conjunction with the Micro-Fit 3.0 receptacle, it is possible to convert PCBs easily from solder to press-fit applications to reduce designs. The pinhole-like shape ensures a reliable connection, added Rutronik.

If applications are to be equipped with connectors that require lower insertion and withdrawal forces or tolerate frequent mating cycles for longer, the Micro-Fit 3.0 RMF is a pre-lubricated version which can be mated up to 250 times. It fits into Micro-Fit 3.0 standard housings. The RMF contacts are available in 20 to 30 AWG.
