TK2D, 2TK2D, 3TK2D, 6TK2D Panel Mount, or use
with TKAD to Mount on DIN Rail and A Series Rail

SNAPTRACK Channel can
be mounted on standard
DIN rails or A Series rail
when used with TKAD.
(Rails not included.)

SNAPTRACK Channel is a
nonconductive, rigid
extruded PVC chassis used
for mounting socket
assemblies and custom
circuit boards. Available in
a variety of fixed widths,
including a split-apart
version for wider PCB
applications, SNAPTRACK
Channel mounts to panels
quickly with rivets or
screws.

Printed circuit boards are
simply snapped-in from the
front, then held securely via
intergral ribs which also
serve as shock absorbers
when the PCB is flexed.
SNAPTRACK Channel
permits easy, convenient
PCB removal for field
service. Slots on 2-inch
centers are provided for
fast, easy installation using
either plastic rivets or other
hardware. Double-faced
tape may also be used
effectively.
