Here’s a comparison of the performance and limitations of inductive, capacitive, photelectric and ultrasonic proximity sensors.

The reflective optical sensor (OS1) is directly attached to the input of the photoelectric sensor main circuit based on the popular 8-pin dual-voltage comparator chip LM393 (IC1). Output from the ...

Reflective object sensors are ideal for non-contact detection of materials such as paper, labels, white plastic, and many other reflective materials. The Phototransistor of a reflective object sensor ...

Proximity sensors are common enough in automation projects that we hardly give them a second thought — pick something with specs that match the job and move on. But they can be fussy to get a… ...

Reflective sensors also have a CTR. Since the sensor depends on reflected light, the CTR is dependent on the type of surface and the distance of that surface from the sensor. The CTR of a reflective ...

Similarly, optic cables can reside next to high-voltage cables in plenums. Reflective light sensors (RLSs) are frequently employed to sense an object's presence because they are easy to use.

Non-contact EchoPod® and EchoTouch® reflective ultrasonic liquid level sensors feature Flowline’s proprietary Reflective Technology™ that delivers reliable level measurement in condensing environments ...

Würth Elektronik has revealed two reflective optical sensors. These are simple devices, with an infra-red emitter and a photo-transistor, both facing upwards, but work at an unusual wavelength. “These ...

[Sebastian Steppeler] has been hard at work on his optical sensors for an electric piano. When we looked in on the project back in October he was testing reflective sensors to increase responsivene… ...

Unveiled as the industry's first reflective color sensors, the TRS1722, TRS1755 and TRS1766 are designed to both emit and detect red, green and blue (RGB) colors, respectively. The sensors combine ...
