EARMOR M51 PTT Module – Kenwood 2-pin

EARMOR M51 PTT Military Module

The M51 PTT module is an essential part of any tactical headset and radio setup. Simply connect it between your radio and a headset equipped with a Nexus TP-120 connector to gain instant Push-To-Talk communication at the press of a button. The large PTT button provides a positive tactile feel and is easy to operate even while wearing gloves, making it ideal during movement or high-stress situations. The housing is made from durable polymer, offering excellent durability without adding unnecessary weight to your equipment. On the back, you'll find a sturdy removable metal clip for attaching the unit to MOLLE webbing, a belt, or shoulder straps, ensuring it's always within reach. A practical addition is the 3.5 mm side port for connecting an external remote button (such as the M50 finger PTT switch). The M51 is primarily designed for EARMOR headsets. While it may work with other TP-120 compatible headsets, compatibility cannot be guaranteed. It is not compatible with Z-Tactical, TAC-SKY, or Element products.

Frequently Asked Questions (FAQ)

Will it work with a Baofeng UV-5R?

Yes. The Kenwood 2-pin connector is specifically designed for radios like the UV-5R and is also compatible with most clones and similar models from Wouxun or Retevis.

Will it work with headsets from other brands?

If they use a genuine Nexus TP-120 (NATO standard) connector, compatibility is likely. However, many budget brands such as Z-Tactical or Element use different wiring, so compatibility cannot be guaranteed.

What is the 3.5 mm side port used for?

It allows you to connect an external remote PTT button, such as a finger switch or weapon-mounted switch. It's ideal when you want instant communication without reaching for your vest.

Where should I mount the PTT on my gear?

The ideal location is on your shoulder strap where you can press it instinctively without looking. Avoid mounting it too low or too far to the side. As a general rule, place the PTT on the opposite side of your shooting shoulder—for example, if you shoulder your rifle on the right, mount the PTT on the left.
