Standard Motor/LVDT Bulkhead Patch Panel
Many beamline components have several axis
of motion
that are used to align and orient optics (mirrors, apertures, crystals, etc.) in
the synchrotron radiation beam. These motors often have an LVDT position
indicator attached to the mechanics of the motion. It is now standard practice
to mount a bulkhead patch panel to a convenient location
on the component
support structure.
A motor extension cable is hardwired to the panel connector on one end and a 12 pin Burndy (GOB14-92 PNE) connection on the other end. The extension cable is run to the motor where it attaches to the motor connector. The extension cable is permanent but the motor, with its attached connector, can be easily changed.
An LVDT extension c able is hardwired to the panel connector using an 8 pin Burndy (GOB12-88 PNE) connector and is run to the LVDT end connector which is an GCA-121-1000. The LVDT connector matches up to the extension cable directly.
The bulk head patch panel is made with enough clearance for fingers used in attaching the Burndy connectors. There is also enough room to place na me labels for each motor and LVDT.
The standard motor cable runs from the bulk head patch panel to the motor drivers.
