RS PRO Magnetic Pickup

Not polarity protected, any momentary reversal of the supply voltage will destroy the device. Digital Magnetic Pick-Up. An ‘active ‘ version of the standard type (Stock no. ; 304-166 304-166 ) but incorporating an IC to provide a digital output compatible with most logic systems Requires a peripheral speed greater than 250mm per second to operate Rise and fall times and amplitude of the output pulse are independent of the characteristics and speed of discontinuity Output Characteristics: With no discontinuity moving in fromt of the pole piece, the output voltage will be less than 0.15V. For each discontinuity passing the pole piece, a positive pulse will be produced. To calculate the output pulse amplitude for various loads the following relationship may be used:. V ;sub>O ;/sub> = V ;sub>S ;/sub> x R ;sub>L ;/sub> / (R ;sub>L ;/sub> + 5000) Where V ;sub>O ;/sub> = Amplitude of output pulse (Volts) V ;sub>S ;/sub> = Supply voltage (volts, dc) R ;sub>L ;/sub> = Load impedance (ohms) 5000 = Approximate output impedance (ohms)
