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 bracket. 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).

Typical Applications:

• Conduct basic motion experiments
• Measure acceleration of freefall
• Measure pendulum periods
