Product Details
Digital Magnetic Pick-Up
An ’active’ version of the standard type (Stock no. 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:
VO = VS x RL / (RL + 5000)
Where
VO = Amplitude of output pulse (Volts)
VS = Supply voltage (volts, dc)
RL = Load impedance (ohms)
5000 = Approximate output impedance (ohms)
