Product specication
Rotational speed sensor
KMI15/4
FEATURES
Digital current output signal
Zero speed capability
Wide air gap
Wide temperature range
Vibration insensitive
EMC resistant.
DESCRIPTION
The KMI15/4 sensor detects rotational speed of ferrous
gear wheels and reference marks(1).
The sensor consists of a magnetoresistive sensor
element, a signal conditioning integrated circuit in bipolar
technology and a ferrite magnet. The frequency of the
digital current output signal is proportional to the rotational
speed of a gear wheel.
PINNING
(1) The sensor contains a customized integrated circuit. Usage in
hydraulic brake systems and in systems with active brake
control is forbidden. For all other applications, higher
temperature versions of up to 150
°C are available on
request.
CAUTION
Do not press two or more products together against their
magnetic forces.
