Introduction
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.
Additional Features
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.
