4.00mm (.157”) Pitch
Positive-Locking Terminal
Block System
FEATURES AND SPECIFICATIONS
Bring up to 10 amps of power directly to the board while conserving PCB real estate
39484 Tin-plated Plugs
39485 Tin-plated PCB Headers
The new 4.00mm (.157”) pitch positive-locking
terminal block connection system from Molex takes
our already popular and patented design to the next
level. Modeled after our 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.
sacrificing performance. The unique positive-locking
feature requires a standard screwdriver to disengage
the plug from the header. Once mated, the connection
is secure even in vibration-prone applications.
Molded from a glass-filled high temperature Polyamide
46, the PCB headers are ideal for applications that
require reflow-solder capability. The positive-locking
terminal block connection system is available in circuit
With today’s trend towards miniaturization, this system sizes 2 through 12.
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
Features and Benefits
n Low-profile design provides a mated mounting height n PCB headers are molded from high-temperature
that is 25% shorter than a standard 5.00mm
(.197”) pitch vertical plug/header mated pair
glass-filled PA46 nylon to withstand reflow-solder
temperatures, which eliminates the need for a
secondary wave- solder process
n 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
n Design of plugs and headers includes a polarizing
feature preventing mismating and also provides an
audible indication when fully mated
