INON z240 Optical (slave) sensor...water sealed

OK, so I've never personally seen or handled one, and the pictures in most catalogs don't focus on this feature.

The optical slave sensor (for fiberoptic sync cabling or "wireless" in the most recent version) appear to be completely sealed up in a glass or plastic potting, with a threaded fitting around it for the Inon fiberoptics. Is it indeed completely water-sealed without anything on top of it, or does it need a threaded "bulkhead plug" like the Ike strobes do for the electrical connections?

My reason for asking is I'm tentatively planning on buying Inon z240's for use with an Ike housing, and hoping I can raise the camera flash enough inside the Ike as the trigger (Ike housing for my body is on order, and be sure I'll test this almost first thing...I know I can 'raise' the flash after installing the camera in the housing by taking a shot that needs it in auto mode. But I've already tested the flash while holding it down from being deployed to full height, and there is a threshhold beneath which it will 'know' it's not deployed and no longer flash. So a lot will depend on this test...) And...I'm cheap, to a point. I'm willing to pay for good strobes. BUT....I wanted to rig up my own substitute fiberoptic cables vs. purchasing something that runs $80-100 (each) for a 2 to 3' length of plastic. I mean, seriously.

So assuming my body flashes inside the housing with the flash actuated, I need to shield it from generating backscatter near the lens. After which, I can probably rig something that will either just 'cap' over or actually thread into the sensor threading at the strobe end, that I can mate up with any old generic endglow fiberoptic cable I can buy (probably can get >20ft for $20). At the camera end it'll be even easier...just shape a chunk of plastic that I screw down to the new top-mount on the Ike DSLR housing (the shield), and bore two holes to poke the other end of the fiberoptics thru. But in the end, I strongly doubt I'll end up with a water-tight seal with my cheezy-arse sync cables at the strobe ends.

So...am I right? Are the optical sensors as they stand, with no connections, sealed for use underwater?

TIA for any responses.

short answer. "Yes".

It's completely waterproof: the cap is just for shock and dirt protection (no o-ring). The newest versions are very sensitive, which can actually cause problems unless extraneous sources of light are blocked from the sensor. This makes off-camera remote use a bit tricky.

Thanks, so anything I can find that can screw into the same thread as a holder - or for that matter, a rubber plug of some sort with a hole bored into it on one side big enough for the sensor, and on the other side big enough for a fiberoptic, would let me mate up a homemade fiber to it.

For making home made fiber optic cords, you can buy an Inon cap which has a removable center section (it has a c-clip). The Toslink cables from Monovision fit right in the hole of the cap.
