How to select the matching M23 connector cable (number of pins, current, shielding) for the servo motor system?

To select the appropriate M23 connector cable for the servo motor system, you need to consider the following key parameters:

1. Pin Count

Choose the pin count based on the number of functions required by the motor system (such as power supply, grounding, brake, encoder A/B/Z signal, temperature feedback, etc.):

Application	Recommended Pin Count
Basic power only	6~8 pins
Power + brake	8~12 pins
Power + encoder	12~16 pins
Power + encoder + temperature	16~19 pins

2. Current Rating

Based on the motor power, select the conductor size that meets the rated current:

Current (A)	Recommended Wire Gauge
≤ 6 A	AWG 22–20
6–9 A	AWG 18
≥ 9 A	AWG 16–14

3. Is shielding required?

When there is an encoder or feedback signal, it is recommended to use shielded cable to prevent interference.
It is also recommended to shield the power cord to reduce EMI interference.
