Motorola HT 750/1250/1550 accessory connector.

[coling223]

I am looking for a bare multi-pin accessory connector for the Motorola HT 750/1250/1550 series radio for a project.

I'm just looking for something I can either solder into, or has a short length of cables coming out of it- a breakout connector, if you will.

Based on my searching, it should be an "M2" connector.

Likely due to a terminology issue, I am unable to find something that will work, plenty of adapters to the M1 style, but nothing that will get access to all the pins.

Thanks in advance for your assistance.

Why not just buy a speaker mic online and cut the end off? They can be found for pennies online. And if you buy 2 or 3 you can have extra pins and connectors if you really need all 13 pins

Pretty rare to find one of those without going through some old Motorola parts catalog and hoping some shop has one that fell behind the shelves that didn't get tossed.

Seriously, those of us that do this stuff just use old speaker mics. Speaker mics commonly fail, so usually there's some old ones laying around that get cannibalized for parts.

Check around on e-Bay or the like and just buy the cheapest old/used mic you can and use that.

The HT750/HT1250/HT1550 accessory connector is the M4. The M2 is a threaded 3.5 mm connector for the Visar series which is also the same connector used with the Jedi and some XTS series audio accessories.

In order to use the M2 single pin connector on a HT750/HT1250/HT1550 series radio you would need the M4 multi-pin accessory connector adapter to a M2 single-pin.

As for a bare M4 accessory connector, I would contact an audio accessory dealer such as Klein Electronics, Planet Headset, Rugged Radios, Racing Electronics, etc. and see if they'll sell just the multi-pin connector. If not, you would need to buy an audio accessory such as a speaker mic or an earpiece wire kit and just whack off the connector.
