Tech Note 317 Detail

Ball ramp with new photogate head

Affected Products:

ME-9806 IDS Photogate Brackets (set of 2)
ME-9385 NOT A VALID PART NUMBER

Problem/Symptom:
I have replaced my older smart pulley (ME-9385) with a new photogate head (ME-9806). Now the diameter of the 3/4" steel ball does not travel through the light beam. Which spacer is required to use the ball ramp from ME-9389 (smart pulley accessory kit) with a newer photogate head, such as ME-9806?

PASCO Solution:
Add a 3/8 inch spacer (615-046) to the present standoff attached to the ball ramp. Change the 1/4-20 x 3/8 screw to a longer screw 1/4-20 x 3/4 (613-067). This allows the diameter of the ball to cross the light beam in the ME-9806 photogate.
