Precautions for Use
1. The connector could be damaged if it is pulled out forcibly. When it is hard to pull out, push it in slightly first and
then depress the lock and un- mate.
Please refer to the " DF51 Series Mating/ Unmating Operation Instruction Manual" ( ETAD- H0847- 00) for handling
precautions during mating.
2. When inserting a crimped contact into a socket, please refrain from inserting at a diagonal as doing so may affect
performance reliability.
Refer to the " DF51 Series Cable Assembly Procedure" ( ETAD- H0923- 00) for precautions during cable assembly.
