The PASCO ME-9498A Photogate Head has a narrow infrared 
beam and a fast fall time that provide very accurate signals for 
timing. When the infrared beam between the source and detec-
tor is blocked, the output voltage of the photogate is low, and 
the red LED (light emitting diode) on the photogate goes on. 
When the beam is not blocked, the output voltage is high, and 
the LED is off. 

The cable included with the Photogate Head is detachable from 
the unit. One end of the cable is a RJ12 telephone plug that con-
nects to the RJ12 jack in the photogate housing. At the other 
end, a stereo phone plug connects directly into a PASCO Photo-
gate Timer (ME-9206B and ME-9215B), PASCO Smart Timer 
(ME-8930), or into any PASCO interface with digital channels 
or a PASPORT Digital Adapter (PS-2159). See the PASCO web 
site at www.pasco.com for more information.

The raised slot on the housing provides a seat for attaching a 
PASCO ME-9450A Super Pulley using a PASCO SA-9242 Pul-
ley Mounting Rod or a 1/4-20 0.375 inch thumbscrew.
