The RPLR series of linear-rotary feedthroughs uses a 3/4″ diameter probe actuated by a rack and pinion positive drive. The independent rotary actuation is achieved by a second rotary feedthrough. Only the 3/8″ diameter probe tip rotates, keyed with a ball bearing keyway allowing mounting of jaw-type devices which are actuated by the rotary action.
Remote Rotary Operation (for RPLR only)
Rotary Limit Switch Actuator Assembly
Stepping or Synchronous Motorized Rotary Feedthrough
NOTE: The /MS or /MY motor option is suitable for the linear actuation when the operation is horizontal. When the linear travel is other than horizontal, the /MS/W option should be used.
We strongly recommend the use of limit switches on this or any other motor drive being used to actuate the linear drive on the RPL or RPLR. The limit switch actuator assembly specified below (or one similar) should be used to protect the RPL or RPLR from being over-driven. See the RLS rotary limit switch option.
Stepping or Synchronous Motorization with High Precision Worm Drive
NOTE: This motor drive is self-locking. This is necessary to protect the probe and associated equipment from spinning down if the power is removed from the motor. However, because of the self-locking design, the drive can generate significant torque at the FRM, and thus do damage if over driven.
