PHOTOGATE
Introduction
The PASCO Model ME-9204B Accessory Photogate fea-
tures a Photogate Head with a narrow infrared beam and
a fast fall time that provide very accurate signals for tim-
ing. When the infrared beam between the source and de-
tector is blocked, the output 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 is high,
and the LED is off.
The cable assembly included with the Accessory
Photogate is detachable from the unit. One end of the
cable is a RJ12 telephone plug that connects to the RJ12
modular jack in the photogate housing. At the other end,
a stereo phone plug connects directly into a PASCO
Photogate Timer (ME-9206B and ME-9215B) or into any
PASCO interface with digital channels (ScienceWorkshop
500 I and 700 I). Please note that the ME-9215B has a
memory function which allows signals from two
photogates (the built-in photogate on the ME-9215B and
the ME-9204B) to be stored and retrieved.
The Photogate Head also includes a small rod clamp and
thumbscrew for attaching the unit to the base and support
rod included with the product, or to any quarter inch di-
ameter support rod.
Additional Features
The raised slot on the housing provides a seat for attach-
ing the PASCO ME-9450 Super Pulley.
