Proximity
Proximity Sensors
Proximity sensors are able to detect the presence of nearby objects without any need for physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation such as infrared and then senses changes in the field or return signal.
We stock a wide range of Proximity Sensors to get your STEM, electronics, or robotics project aware of its surroundings!
