Electronic – What kind of “locking” barrel connector is this

connectorpower supply

I am looking for a replacement for a barrel connector; this is a locking connector (PN: PWRS-14000-260R for a Motorola FX9500 RFID Reader Country of origin: CHINA) however the locking 'fins' (for lack of a better description) are located on the sleeve instead of more commonly (?) nubs on the plastic tip

Even knowing the plug specifics (2.1mm x 5.5mm inline plug (Female)) and providing measurements of these 'fins'(are about .5mm tall x 2.7mm wide and stick out of the barrel sleeve about 7.5mm from the end of the plastic tip) and contacting Digi-Key and Condor Electronics with pictures, I am unable to find anything on this plug type.

I am beginning to think that this is a proprietary plug made specifically for Motorola by LEI and Motorola is NOT good about providing vendor info (I'm finding out).

Any ideas on what this particular connector is referred to as and if they can be found anywhere commercially?

It looks like the company in the next link sell these connectors: http://www.cliffuk.co.uk/products/dcconnectors/

the specific datasheet: http://www.cliffuk.co.uk/products/dcconnectors/DCPlugSocketLockable.pdf

You can check if they have an distributor in your country and get it from there. Hope this helps you!
