Product speciﬁcation

Integrated rotational speed sensor

KMI16/1

DESCRIPTION

The KMI16/1 sensor detects rotational speed of ferrous

gear wheels and reference marks.

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 the target wheel.

The open collector (OC) output allows for a high degree of

flexibility in the design of subsequent conditioning

electronics.

PINNING

CAUTION

Do not press two or more products together against their

magnetic forces. Do not expose products to strong

magnetic ﬁelds of more than 30 kA/m.
