Positive Locking Terminal Blocks Connection System The new 4.00mm (.157") pitch positive-locking terminal block connection system from Molex takes their already popular and patented design to the next level. Modeled after the Eurostyle™ Series 39980, 5.08mm (.200") pitch and Eurostyle Series 39990, 5.00mm (.197") pitch products, this 4.00mm (.157") pitch system performs exactly the same as its larger relatives but takes up less space on the board.
With today's trend towards miniaturization, this system allows customers to use up to 12 AWG wire to bring 10.0A of current directly to the board with a smaller pitch, conserving valuable PCB real estate without sacrificing performance. The unique positive-locking feature requires a standard screwdriver to disengage plug from header. Once mated, the connection is secure even in vibration prone applications. The positive locking terminal blocks connection system is available in circuit sizes 2 through 12.
