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)
VO = Amplitude of output pulse (Volts)
VS = Supply voltage (volts, dc)
RL = Load impedance (ohms)
5000 = Approximate output impedance (ohms)


Not polarity protected, any momentary reversal of the supply voltage will destroy the device.


Magnetic Pick-Ups

Miniature magnetic 'pick-up' transducers suitable for use in a wide range of sensing applications. Each device responds to movement of ferrous parts past the pole on the end of the unit. Used extensively in areas such as speed regulation of motors, when sensing for example, the teeth on a gear wheel. However, magnetic pick-ups may be used to implement feedback and control functions in many fields. Automotive applications include crank angle sensing, ignition timing, anti-skid systems and diagnostics. Applications in the computer peripherals area encompass disc drives, line printers, card punches/readers and printer terminals. The diagrams indicate the two basic modes of using these components. Note especially their small size in relation to their high signal output, enabling their deployment where many conventional sensors cannot be fitted. Fully encapsulated construction for reliable operation, but not intended for immersion in liquids.
