MaxSonar-UT -- a unique ultrasonic generator If you want to create a real robot on your own, then you will certainly need a unique product by MaxBotix. Maxbotix produces MaxSonar-UT - unique ultrasonic generators in a pint-size plastic casing designated for use in sonars of 38-42kHz. Such generators have sound pressure of up to 117dB and fast response of up to 60dB. All these features make it possible to produce maximum portable and economical transceivers on a basis of MaxSonar-UT with low supply voltage, such as MaxBotix sonars of LV-MaxSonar-EZ series. The indicator's characteristics: - sensitivity (SEN): --60dB (0dB = 1V/u bar) - electrical impedance: 1kHz - sound pressure (SPL): 117dB (0dB=0.2n bar) - pulse duration: less than 1 ms - capacitance: 2400pF ±20% - operating frequency: 38kHz...42kHz - applied voltage: maximum 20V RMS (maximum 60V peak-to-peak by 10% pulse duration). MaxSonar-UT ultrasonic generators are designated for -40°C - +65°C temperature range.
