Light Gate - Ipc

This timer is most suited for an investigational approach for students to gain a sound understanding of the concepts of time and motion. Two pairs of sockets alternately start and stop the timer, one pair operating in make mode, the other in break mode. The start/stop switches can be either mechanical or electronic. The timer is autoranging for ease of use and has a clear 13mm LED digital display. Built into a robust metal case with a durable powder coat finish. An illuminated on/off switch is mounted on the rear panel adjacent to a fused appliance inlet.We recommend using this timer with the IPC Light Gate (code 80082) for all start/stop timing applications due to its ease of use, accuracy and repeatability. Light gate comprises photodetector and light source each housed in a robust ABS case spaced 40mm apart on a plastic rod. Light source housing has battery compartment and on/off switch. Photodetector housing is fitted with a pair of 4mm sockets to allow connection to electronic timers. When the timing gate is switched on it creates a short circuit between the two output sockets, this then becomes an open circuit each time the light beam is interrupted. Consequently, the timing gate can be used as a remote switching device in a wide range of dynamics experiments.
