Motorola NKN6512A CommPort Ring PTT Replacement Cable – Finger PTT for APX, XTS & HT Radios

Motorola NKN6512A CommPort Ring PTT Replacement Cable – Finger PTT for APX, XTS & HT Radios

The Motorola NKN6512A CommPort Replacement Ring PTT Cable (also sold as the NKN6512) is the genuine Motorola 2-wire replacement cable with a finger-worn ring push-to-talk for the Motorola CommPort ear microphone system. The ring PTT slips onto a finger, so you can transmit with a slight thumb press while your hand stays relaxed, on a weapon, on a steering wheel or holding equipment. No visible button or reaching for the radio is needed. It’s the most covert PTT option for CommPort. One end connects to your CommPort earpiece and the other to a Motorola radio adapter. The coiled cord stays neat under a sleeve.

Undercover officers, surveillance teams, SWAT and tactical operators, and executive protection details choose the NKN6512A when transmitting must go unnoticed. It works on Motorola APX, XTS, HT, MTX and SRX 2200 radios.

Frequently Asked Questions

What is the Motorola NKN6512A?

The NKN6512A is Motorola’s CommPort replacement cable with a finger-worn ring push-to-talk. It’s a 2-wire coiled cable that connects a CommPort earpiece to a Motorola radio adapter.

What is a ring PTT?

A ring PTT is a small push-to-talk button worn on a finger like a ring. You transmit with a thumb press, so you can talk without visibly reaching for the radio or a button.

Does the NKN6512A connect directly to my radio?

No. It connects to a Motorola audio adapter: the BDN6783 for APX 6000, APX 7000 and SRX 2200 radios, the BDN6676 for XTS and older models, or the AAHLN9717.

Should I choose the ring PTT or the palm PTT?

Choose the NKN6512A ring PTT for the most covert transmitting. Choose the NKN6510A palm PTT if you’d rather hold a button in your hand, or the NNTN4188A body switch for hands-free use with gloves.

When should I replace my CommPort ring PTT cable?

Replace it when the cable is cut, frayed or crushed, when audio or transmit cuts in and out, or when the ring PTT stops working reliably.
