The PMDX-Heatsink-01 is a large finned aluminum heatsink for Gecko stepper or servo drivers

  • The heatsink is pre-drilled and tapped for mounting with 6-32-1/4" screws
  • The hole pattern is aligned properly for use with PMDX-133 or PMDX-134 motherboards for stepper drivers (It is not suitable for use with the PMDX-132 due to different hold spacings)
  • It can also be used with discrete wiring when a motherboard is not desired or when using servo drivers
  • Designed large enough to be used without a fan when mounted through the wall of a control box with the fins on the outside and the Gecko drivers on the inside, and with the long axis of the fins in a vertical orientation. 
  • Can be used as an internal heatsink with adequate air circulation.
  • The heatsink is 12" long and 5.375" inches wide. It weighs over 4.4 pounds and provides over 250 square inches of surface area on the finned side.
