Expert Questions Answered

What's the advantage of the IP67 rating?
It allows installation in washdown areas or dusty environments without needing an extra protective conduit, saving time and cost on installation.

Can I cut this cable to a shorter length?
We strongly advise against it. Cutting the cable will destroy the factory-sealed connectors and the IP67 rating. Use cable ties to manage excess length neatly.

Is shielding necessary for a brake cable?
Typically not. Brake signals are simple on/off DC power. The unshielded design of the MR-J3BK-10M reduces cost and stiffness while being perfectly reliable for this function.

How do I connect the open flying leads?
They connect to the brake terminal block on your MR-J3 servo amplifier. Ensure correct polarity (usually marked + and -) and a secure terminal connection.

Will it fit both HG-JR and HG-SR motors?
Yes, it uses the standard motor-side connector for these series. Always double-check your specific motor model for compatibility.
