New Improved Sensitivity Range - Higher Upper Threshold
Non-latching mini voice/sound activated relay switch. Can be used as a hands-free voice activation switch to operate tape recorders, lights, and a variety of other devices.
We have improved the sensitivity adjustment range by increasing the upper trigger level threshold without compromising low level sensitivity.
Also suitable for use as a simple security device to sound an alarm or activate monitoring equipment.
The 3126 is very sensitive and may be less suited to applications where activation at a higher sound level is preferred. Better results may be obtained using the Cebek PM-14 module.Features
