Photoelectric sensor

The kit consists of two photocell sensors (type A and type B). The sensors are photocells with an infrared emitter and an infrared receiver at both ends. Sensors are used to measure the time spent on an event and on a series of events. Sensor-photocell type A is used alone or in pair with a photocell sensor type B. Sensor-photocell type B is used only in conjunction with a sensor type A. The set of sensors can be used in standard experiments: studying free fall; momentum theorem; study of the laws of kinetic energy; study of Newton’s second law. The set of sensors corresponds to the following parameters:
1. Measurement range: from 1 μs to 99 s;
2. Resolution: ≥1 μs;3. Accuracy: ≤±2%.
The sensor is equipped with a socket to interface with the data recorder. It has a mounting hole for its fixation during experiments.
