April 1, 2009 - Molex announced a terminal block connection system that takes up less space on a network board while performing exactly the same as the larger version. The new 4.00mm (.157”) pitch positive-locking terminal block connection system conservs valuable PCB real estate without sacrificing performance.
The design is modeled after Molex Eurostyle Series 39980, 5.08mm (0.200”) pitch and Eurostyle Series 39990, 5.00mm (.197”) pitch products.The low profile design of the 4.00mm (0.157”) pitch system -- 39484 Tin-plated Plugs and 39485 Tin-plated PCB Headers -- provides a mated mounting height that is 25% shorter than a standard 5.00mm (0.197”) pitch vertical plug/header mated pair.In addition, the unique positive-locking design requires a screwdriver to unmate the plug from the header, ensuring a secure connection in vibration-prone applications and reduces the overall space required on the board by eliminating the need for traditional mounting ends.Molded from a glass-filled high temperature Polyamide 46, the PCB headers are ideal for applications that require a lead-free reflow-solder capability.
The positive-locking terminal block connection is available in circuit sizes 2-12.Applications for the 4.00mm (.157”) Pitch Positive-Locking Terminal Block system include:
- Instrumentation
- Sensors and transmitters
- Programmable logic controllers (PLCs)
- Elevator and conveyance controls
- Large-scale integration
- Industrial network interface
- High-end security and building controls “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, and it takes up less space,” said Dan Nigro, terminal blocks product manager, Molex.
“The design of our plugs and headers includes a polarizing feature preventing mismating and also provides an audible indication when fully mated.”
