The PLANET CB-M23F5F-120 is a DC power cable for connecting an industrial managed switch with a five-pin male M23 power input. Its 1.2 m length gives you room to position the power source, with a five-pin female M23 connector at one end and bare wires at the other.
The manufacturer’s guide lists it for the switch’s M23 power input and specifies that it is obtained separately. The four assigned conductors are white for V1 positive, brown for V1 negative, black for V2 positive and yellow for V2 negative.
For this connection, the guide specifies 24–48 V DC input and 12–24 AWG cable wire gauge. The bare-wire end connects to a DC power source; the M23 connector mates with the switch’s power input.
