3 pairs)
Recommended connector (on the JA54 side): A02B-0120-K303
Recommended cable : A02B-0259-K821 (7 m). When using the cable,
rewrite the connector name.
The maximum allowable length is 50 m. However, another limitation
based on a power supply voltage drop is imposed as described below.
Limitation based on a power supply voltage drop
Suppress the power supply voltage drop due to cable resistance to 0.2
V or less (sum of the 0V and 5V lines).
