The Photogate Head monitors the motion of objects passing through its gate, counting events as the object breaks the infrared beam.
Includes a swivel mount to attach to a photogate stand. It does not include the heavy base and standard rod of the Accessory Photogate (ME-9204B). Can be used with ScienceWorkshop interfaces or with PASPORT interfaces using Digital Adapter (PS-2159).
