Configuration

Flange front: thread holes/center thread Flange back: plastic ring/external thread/with opening Shaft front: length/diameter Shaft rear: length Electric connection: cable length/pin connection/connector 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). Connection NTC (Cable AWG 26) purple NTC purple NTC Resistance 25°C: 10 kOhm ±1%, beta (25–85°C): 3490 K
