Configuration

Flange front: thread holes/center thread Flange back: plastic ring/external thread/with opening Shaft front: length/diameter Electric connection: cable length/pin connection Temperature Sensor: NTC-Thermistor Appropriate connectors and connecting cables are available for the configuration of the pin connection together with the external thread: see catalog, Accessories section.

Wiring diagram for Hall sensors see page 47. In combina- tion with the ENX EASY INT, the orange (V CC ) and blue (GND) connections are not used. Hall signals are then generated by an ENX EASY-INT sensor (no pull-up resistor required; output signals: CMOS compatible push-pull stage).
