This U94 PTT cable adapter is designed for Motorola 1-pin 2.5mm radios. The radio-side connector is a single 2.5mm plug, while the headset side is made for U94 / U-94 style tactical headset systems. This is the most important fitment distinction for this product type and should be confirmed before purchase. Public same-type listings also describe this format as Motorola 1-pin 2.5mm used with U94-style PTT headset systems. Compatible Motorola radio models commonly listed for this adapter family include T270, T280, T289, T4800, T4900, T5000, T5100, T5146, T5200, T5300, T5320, T5400, T5410, T5420, T5500, T5600, T5620, T5700, T5710, T5720, T5725, T5728, T5800, T5820, T5900, T5920, T5950, T6200, T6200C, T6210, T6220, T6222, T6250, T6300, T6310, T6320, T6400, T6500, T6510, T6550, T7100, T7150, T7200, T7400, T7450, Spirit GT, Spirit GT+, FR50, and FR60.
