Honeywell Digital Magnetic Speed Sensors

These digital magnetic speed sensors combine the features of VRS sensors with a self-contained switching circuit. This circuit changes the waveform generated by the sensor coil into a digital square-wave output. The switching circuit is triggered "on" by the positive-going leading edge of the sensor coil output and turned "off" when the sensor coil output approaches zero voltage.

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.
