These configurable 2″, 3″, 4″, 5″, 6″, and 8″ subsea housings are great for use on ROVs, AUVs, harsh environment sensing, and other marine robotics applications. Modular end caps give you options – dome, blank, and with holes for cable penetrators. Depth ratings are shown for each component in the dropdown and all technical details can be found below.
When used with the clear acrylic plastic tube option, it''s easy to see the components inside the enclosure, ideal for subsea development projects and research ROVs and AUVs. The aluminum tube option provides a greater depth rating, opaque appearance, and better thermal transfer for high power applications like power supply housings and battery housings.
The acrylic tubes are cast optically clear material, like the previous generation, but the inner ends are now precision machined so that despite wide tolerances on the raw plastic material, the O-ring interface is always manufactured to tight tolerances. The aluminum tube options are also precision machined for an excellent fit. A smooth surface finish ensures proper sealing between the O-ring flange and the tube and a smooth O-ring lead-in shape makes it easy to insert the flange without damaging the O-rings.
Because of the precision machined interface, the tubes are no longer available in custom lengths, however we have several different length options for each diameter, representing the most popular lengths of custom tubes that were ordered in the past.
The tubes have a slot machined at each end that provides access to insert and remove the locking cord. That slot doubles as the mating point for a key that is machined into the flange. The key inserts into the slot so that the flange can only be installed in one orientation, preventing the end cap or flange from being rotated and damaging internal components.
The locking cord is a new feature in this generation of watertight enclosures. The locking cord allows you to secure the flange to the tube so that they cannot be separated unless the cord is removed. There’s a half-circle shape machined into the inside of the tube and a matching half-circle shape machined into the flange. Once assembled, a round plastic locking cord is inserted into the circular space, preventing the flange from being removed from the tube.
The locking cord is included with the enclosure and comes with a small anodized aluminum handle that can be attached to make the cord removal as easy as possible. Alternatively, if you want to make the enclosure tamper-resistant, you can cut off the cord and cover the insertion slot. This is suitable for finished products that are not intended to be opened by the user.
Exclusively for the 2″ Series enclosure is a shift to combining the sealing flange and end cap into one part: the flange cap. While the flange seal is still available to handle the clear, dome, and custom end caps, the flange caps offer a combined solution that does not require any screws or assembly. There are zero, two, and four hole versions of the flange cap with threaded M10 holes to suit our cable penetrators.
The watertight enclosures are available through this configuration page, which lets you select a tube, flanges, end caps, vent, and more. You can also purchase components separately if you prefer.
¹An O-ring flange must be selected in the configurator when selecting end caps. A flange is not required and will not be selected when selecting the flange cap option for the 2″ series enclosures.
The standard thread for most Subconn and Seacon type "MCIL" connectors is 7/16"-20. The 10mm holes in the end-cap are the perfect size to be tapped for that threading. A tap like this one can be used to make the proper threads. Depending on the endcap, some holes are spaced closer together, preventing the installation of two connectors immediately adjacent.
