Photogate, with removeable Pulley

The Photogate can be connected directly to an interface, or, in a daisy-chain configuration, up to five photogates can be chained to a single interface channel. The Photogate includes a BT cable for connection to an interface, a pulley attachment and a steel support rod for mounting it to a stand. An IEEE1394 cable for connection between photogates can be ordered separately (CMA art. nr 07662). In the external laser gate mode, a fast visible light detector located at one of the photogate arms responds to the presence of a low-power laser beam. This external gate requires a visible pen laser (not supplied).

Technical specifications of the photogate sensor are described in the product manual, see downloads.

Photogate BT63i can be used for a wide variety of experiments:

measuring the acceleration due to gravity (use a transparent piece of plastic with stripes at regular intervals, which can be allowed to fall through the photogate),
studying the swing of a pendulum
measuring the speed of a moving (rolling) object
timing the period of a rotating object
measuring the speed of objects undergoing collisions
measuring the liquid volume (drops) during a titration

The Photogate can be connected to analog BT inputs of the CMA interfaces.

A ‘P4272-1K BT sensor cable, single’ is required to connect the sensor to the interface.
Please check whether you already have this cable in your stock.
