• Type: Jumperr

Specifications of 4-1437644-8

• Number Of Contacts: 20POS
• Pitch (mm): 9.53mm
• Gender: SKT
• Body Orientation: Straight
• Insulation Resistance: 5Gohm
• Contact Material: Beryllium Copper

Contact Spacing Options:
.4375 in (7/16") Spacing
Extra thick barriers provide higher
voltage rating. Up to 27 ckts. (25
circuits for end mounted blocks)
Base Options:
Closed Base
Catalog Letter
Code: C. For
terminal junction-
blocks requiring
top connections
only. Useful in
applications
requiring single point circuit
terminations or circuit completion via
top mounted, single- and two-sided
quick-connects. Replace double-row
barrier strips.
Flat Base
Catalog Letter
Code: F. Lends
itself most readily
to applications
where direct top-
to-bottom feed-
through is required with no special
requirement for circuit isolation on the
bottom side. The most common
example of this is printed circuit
board mounting.
Raised Base
Catalog Letter Code R. Standoffs
between each circuit raise block
.030" above mounting surface to
allow flux and solvents to drain
during soldering operations.
Available only with 02 and 04 bottom
terminals.
Turret Base
Catalog Letter Code: T. Combines
top-to-bottom
feed-through
with bottom-side
circuit isolation
for panels up to
.126" thick. Turret
bases are available with the following
terminals: solder tail, quick connect,
machine wrap, extended circuit
board terminal, and right-angle.

Mounting Options:
End Position
Mounting
Catalog Letter
Codes: E, F, G
or M. Supplied
without contacts in end sections to
allow installer to mount blocks with
screws in end section holes. Base of
block will support mounting screws
(Codes F & M). Also available with
mounting inserts installed in end
mounting holes to raise mounting
screw heads to the level of other top
hardware (Codes E & G).
Without End Barriers
Catalog Letter Codes: F, G & H.
Facilitates mounting-screw access
when end sections are used for
mounting.
Direct Mounting
Catalog Letter Codes: P & H. SSBs
may be solder-mounted using the
bottom terminals themselves, as in
the case of printed circuit board
applications.
Direct mounting is also possible with
turret base models using press-on
retaining clips (Catalog No. L97, Part
Number 1437661-7) on turrets.
