Description

Ergonomic DTMF Keypad Palm Microphone with Emergency Alert Button

High-performance keypad microphone with 10-pin aviation connector for Hytera HM and MD series mobile two-way radios.

The Hytera SM19A1 is an original equipment manufacturer (OEM) keypad palm microphone engineered to enhance operational control and voice clarity for Hytera commercial mobile transceivers. Featuring a full Dual-Tone Multi-Frequency (DTMF) numeric keypad, large programmable function keys, and a dedicated orange emergency call button, this palm microphone enables vehicle operators and dispatchers to manage selective calling, manual channel entry, and immediate emergency signaling directly from the microphone housing.

Built for heavy-duty daily use in public safety, transportation, and industrial fleets operating on DMR Association digital networks, the Hytera SM19A1 features an IP54 weather-rated casing that resists dust accumulation and water splashing. The durable coiled cable connects via a secure 10-pin aviation interface connector, ensuring a stable electrical connection that prevents accidental disconnects during rough vehicle travel. A metal dash-mount clip is included for easy mounting on vehicle consoles.
