No pull-up resistor required. Hall signals are generated by an EASY INT sensor. In combination with the ENX EASY INT, the orange (VCC) and blue (GND) connections are not used. Connection Temperature sensor (Cable AWG 26) purple NTC Flange front: thread holes/center thread Flange back: plastic ring/center thread Shaft front: length/diameter Electric connection (only for motor type A): cable length/ pin connection/connector Temperature sensor: NTC-Thermistor (only for motor type A and only when not combined with an encoder). Appropriate connectors and connecting cables are available for the configuration of the pin connection together with the external thread: see catalog accessories section.
