HAL Interface Connector
Depending on the sensor type, up to two sensors can be connected to the board. For
this purpose, a 6-pin connector HAL1/2 is provided. Alternatively, one Hall Sensor can
be inserted in the 3-pin socket HAL beneath the connector HAL1/2 (only available for
boards without housing).
The following pin’s are connected in parallel Pin No. 1(V
SUP
Sensor1) and 4
(V
SUP
Sensor2) and Pin No. 2 (Common Sensor GND) and Pin No. 5 (Common Sensor
GND). The male plug (modular RJ-12, OST (MMJ) coding) corresponding to the fawn
connector HAL1/2 can be ordered from every electronics store. The pinning of the inter-
face is described in
