Digital Magnetic Pickups

Complete Manufacturing Flexibility

Xensor pioneered the use of custom IC to digitize the analog signal generated by a magnetic sensor, eliminating the use of expensive hybrid chips or backup electronic circuitry.

Digimag Digital Magnetic Pickups revolutionized the use of magnetic sensors for the computer peripherals industry, where low cost and compact design count.

Providing a digital pulse output sensing a change from non-magnetic to magnetic material moving past the pole piece. The rise-fall times and amplitude of the output pulse is independent of the speed of the magnetic discontinuity. The maximum rise time is 1,000 nanoseconds; the maximum fall time is 50 nanoseconds.
