Provide appropriate strain relief at the readhead. The Renishaw top exit cables
u
are fitted with a P-clip to ensure appropriate cable strain relief.
When using Renishaw's top exit cables ensure that the P-clip is mounted within a
u
50mm radius of the readhead cable exit.
Minimum static bend radius of cores is 3 mm.
u
For challenging dynamic applications consider additional strain relief of the cores.
u
Ensure there is no relative movement between the readhead and the P-clip.
u
u The maximum number of insertions for the readhead connector is 20 cycles.
Care should be taken when removing the connector to avoid pulling out cores
from the cable connector.
Shielding
For optimum performance:
Ensure 100% shielding.
u
Ground the mounting brackets.
u
Ensure continuity between the readhead body and cable shield. For Renishaw
u
top exit cables the P-clip provides electrical connection to the cable shield.
Maximise the distance between the encoder and motor cables.
