View Full Version : Source for db25 shell for locking pins on a Becker 4201?

Becker likes to use slide locks for the db25 connector on the back of the radio.

The ar3201 has a circular pin slide lock - the ar4201 a different locking "hook" hardware set.

Does anyone have a source for such hardware? I've looked in mouser and other online catalogs, but all I find are the standard
screw-in post connectors.

I'd replace the lock hardware on the radio, but suspect I'd have to completely disassemble it to put in new hardware.

This is what I used on my new-to-me AR4201; MHED-DS25S - D Sub Backshell: https://www.newark.com/mh-connectors/mhed-ds25s/25-position-plastic-slide-lock/dp/61W9841?ost=61W9841&ddkey=https%3Aen-US%2FElement14_US%2Fsearch

Newark part number 61W9841 ; cost under $3USD/per. I'm surprised that the normal soaring suppliers don't stock them.

Cheers
Dan

I just removed the factory screws and bracket, then got two of the inside threaded bolts from an old PC and screwed in. Worked great.

A couple of comments;

- Both Cumulus and Wings & Wheels have the Becker locking shells in stock. Unsure about the other vendors.
- While I am not in love with the Becker latching system, preferring the LXNav "bail" type instead, they both have one advantage over the common screw-in type. Which is you can connect/latch the Becker/Filser/LXNav connectors blindly in our tight instrument panel confines.
- See http://aviation.derosaweb.net/presentations/#wiring (slide 47) for details.

Thanks for the comments & presentation link. I didn't see the shell on W&W and I still can't find it on Paul's site.
But no problem... I have 2 coming in the mail from NJ.

Since you mentioned it (on the slide), know of a source for the "Filser/Dittel" sliding catch post-style shell?
That's the type used on my archaic AR3201. Maybe I should just buy a 4201.

The LXNav "bail" type bits for the equipment end of things was "easy" to find. See the link below. But the connector eludes me (other than for Centronics types). Anyone? Bueller? Bueller?

For the record Wings and Wheels lists the Becker latching "shell" as the alternate term "hood". https://wingsandwheels.com/db25-connector-w-slide-lock-and-housing.html

PS - As to the Filser sliding type the link is shown below. Unlike the Becker sliding style which requires a special shell, this item is bolted to a standard DB25 connector (and shell). Enjoy!
