Single channel tachometer (T-401)

The Jaquet T401 single channel tachometer speed switch is part of the T400 series for speed measurement, switching and indicating. The T401 converts absolute speed into an analog signal and has a measuring range between 0-1 Hz and 0-35 kHz. It includes 2 limits (A/B) with programmable hysteresis and one changeover relay. The adaptive trigger provides high noise immunity for use with e.g. electromagnetic sensors. The T401 can be configured via the included Windows® software.
