BZi sensor
(1) Compatibility
The BZi sensor with the drawing number A860-2150-T***, which is described in this document, is
smaller and thinner than the former BZi sensor (A860-2120-T***), and as a result the method to install
the sensor head and the relative axial dimension between the detection ring and the sensor head is
different with each other. Please note that it is necessary to change the design of the sensor mounting
surface and the axial position of the detection ring in order to replace the former BZi sensor with the
new BZi sensor.
The outer and inner dimension of the detection ring is common between the BZi sensor which is
described in this document and the former BZi sensor in case that the number of teeth is the same. It
is not necessary to change the parameter in replacement of the sensor because the electrical
specification of the output signal is common.
