HCM1203AP

RYD HCM1203AP is a Passive Electromagnetic Buzzer with Φ12×9mm dimensions, 3V rated square-wave drive, and 85dB output at 2400Hz. This Passive Electromagnetic Buzzer requires an external driving signal to produce sound, allowing the host system to control tone frequency, pattern, and duration for multi-tone alert sequences. Pre-attached UL1007 AWG26 wire leads enable direct chassis or off-board mounting without on-PCB connectors. Operating voltage range is 2–5V with 100mA maximum current. PBT housing with red copper leads and coil resistance of 16±4Ω. Rated −30 to +70°C. Suited to industrial equipment with panel-mounted indicators, automotive interior assemblies, and consumer electronics where off-PCB buzzer placement simplifies acoustic port alignment. Customization available: wire length, connector type, and ingress protection level per deployment condition.
