Overview
The 28764 is a weather-resistant enclosure that is 10 inches wide and 12 inches tall with two conduits for cable entry. This enclosure houses and protects the SDM8X50 TDR multiplexer. When purchased with the –E option, the SDM8X50 ships with this enclosure and an enclosure supply kit.
Technical Description
The backplate of the enclosure is prepunched with one-inch-on-center holes suitable for attaching the SDM8X50 multiplexer.
The 28764 is shipped with the 7363 Enclosure Supply Kit that consists of desiccant, a humidity indicator card, cable ties, wire tie tabs, putty, grommets, screws, and PVC coupling.
The 28764 has mounting hardware for mounting to a tripod mast or a user-supplied pole with a 1.25 to 2.1 in. diameter. The enclosure has two 1.5 in. diameter cable entry conduits on the underside of the enclosure. Multiple cables can be routed through each conduit.

Replacement Parts
(9)28878
Replacement Enclosure Humidity Indicator Card
The 28878 is a replacement humidity indicator card. It provides a visual reference of humidity level inside the enclosure. Colored circles change color from blue to pink to indicate humidity levels of 30%, 40%, and 50% relative humidity. Double sticky tape on the back of the card allows it to be easily secured to an enclosure lid.
Orderable6316
Universal Backplate for ENC10/12
The 6316 provides a universal backplate for retrofitting older 10" x 12" enclosures. The anodized aluminum backplate is completely pre-punched with a matrix of half-inch-on-center holes. The 6316 replaced the now-retired 5947 Half Universal Backplate, which contained press-in hardware for the CR10 and 21X (upper half) and a grid of 1”-on-center holes (lower half).

Another backplate used in the ENC10/12 is also retired; the 5622 backplate had a special hole configuration that supported the AM32 multiplexer (the AM32 was a much larger predecessor of the AM16/32B).6832
Enclosure Filter with 60 Micron Pore Size
One 6832 filter may be installed in one of the small compression fittings (cable entry seals) in the ENC10/12 to allow air pressure to equalize between the inside and outside of the enclosure. As such, the filter is used only when the cable entry seals option is selected for the enclosure (item 6447). The filter is typically used when a barometric pressure sensor (or, in some cases, the cable termination of a vented submersible pressure transducer) will be located inside the enclosure. The filter has a 60 micron pore size.

ENC10/12 Tripod Leg Mounting Kit
The 18955 provides the same bracket as "-LM" mounting option. This bracket may be ordered as a replacement part, if the bracket gets damaged, or if another option was originally chosen. The 18955 allows the enclosure to be attached to the leg base of a CM110, CM115, or CM120 lightweight tripod.
