added, the SPDC sensor will be sent separately..
The sensor generates two square wave signals with 90°
phase shift for detection of speed and direction of rotation.

Note!
Redundancy possible for some motor/brake/SPDC-
combinations (recommended for e.g. CBm with BICA)
– please contact Hägglunds Technical Helpdesk for

Note!

When ordering the SPDC speed sensor, it must be added in free text in the order form that the sensor shall be mounted
on the motor at the factory. If not added, the SPDC speed sensor will be sent separately.

Unlike the former SPDB1 sensor, there is not a need to dismount the SPDC speed sensor from the motor, when the
motor shall be mounted on the customer shaft. The SPDC speed sensor can therefore be mounted at the factory.

It shall be noted that there are several valuable advantages to have the SPDC speed sensor mounted at the factory, as
some parts of the motor must be dismounted and exchanged by new parts if the sensor is mounted afterwards and not
at the factory.
