Our Digimag Digital Magnetic Pickups have transformed the use of magnetic sensors in the computer peripherals industry, where affordability and compact design are crucial.
These pickups generate a digital pulse output when detecting the transition from non-magnetic to magnetic material passing by the pole piece. The output pulse's rise and fall times, as well as its amplitude, are independent of the speed at which the magnetic discontinuity moves. The maximum rise time is 1,000 nanoseconds, and the maximum fall time is 50 nanoseconds.
