Photogate

Description

The photogate consists in an infrared diode. This diode is located on the transmitter’s side. The receptor consists of a phototransistor which filters a large range of the visible spectrum. When the infrared beam hits the receiver, the phototransistor sends a +5 V to the Signal input. Use: The photogate lets you measure velocities, accelerations, and displacements.
