C-C550/M11 Remote Speaker Mic & Push-To-Talk Controller (TP9361 Ex)

Built for harsh Australian worksites, the C-C550/M11 remote speaker microphone with body-worn push-to-talk (PTT) controller is designed to suit the TP9361 Ex radio, delivering reliable voice communications when conditions are wet, dusty, noisy or glove-heavy. The combined speaker mic and remote PTT format keeps critical controls accessible with the radio positioned under clothing or PPE, helping reduce missed calls, delays and rework during high-tempo operations.

Engineered for industrial durability, this unit is dust-tight and water submersible to IP67, with extensive environmental testing to MIL-STD-810G for blowing rain, blowing sand, dust, immersion, shock, vibration, salt fog, thermal shock and more. That level of robustness supports consistent performance across construction sites, processing plants and mining environments where equipment takes daily impacts and exposure.

For safety and productivity, the oversized PTT buttons provide excellent tactile feedback even with thick gloves, supporting clear, fast transmissions for spotters, plant operators and maintenance crews. Audio output is optimised for high-noise areas, helping teams hear instructions the first time and minimising repeat calls. A coiled cable and secure clothing clip improve comfort and reduce snag risk when moving through tight access ways.

A wired headset interface (QR4+1 female) allows integration with compatible hearing protection and comms accessories, supporting site communication protocols and helping control total cost of ownership through durable construction and reduced downtime.
