The buzzers feature a large DC voltage range from 5Vdc up to 80Vdc. They are equipped with 16 AWG wires for use in harsh industrial environments. Typical power consumption is 15mA at 12Vdc and life time exceeds 2000 hours. The units are wrong-polarity protected and include an O-ring for panel mounting. The devices are protected to IP67 and operate in the -40 to +85°C temperature range. The buzzer starts sounding from 5Vdc. The sound output increases with raising voltage up to 15Vdc. From 15Vdc to maximum voltage of 80Vdc the sound output remains the same.
