Extra-sensory perception: Recent advances in photoelectric technology have produced solutions to sensing problems that were thought difficult — or even impossible — to solve with photoelectric ...

The SA2E general-purpose photoelectric sensor family includes five models which improve or replace SA1E products. The SA2E sensors improve response times to 0.5ms, compared with 1.0ms for previous ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, ... Laser sensor is a type of photoelectric ...

There are many types of sensors on the market, using a variety of technologies. Sometimes these are called discrete sensors, but in general discrete object detection refers to any method of sensing a ...

SA2E PE sensors are extremely compact at 10.8x19.5x31.5mm, and various mounting brackets are available. Sensors are built to operate in a wide range of temperatures from -30 to +55DegC, and an ...

Diffuse sensors with background suppression are available with NPN or PNP light-on outputs. Available are fixed sensing distances up to 600 mm and adjustable models with sense distances from 50 mm to ...

Proximity sensors can be used outdoors under direct sunlight to determine proximation. The ALS/Prox sensor detects, and subsequently cancels out, the ambient IR. It depends on the IR emitter ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The … ...

Here, in this article, let us discuss about the Inductive Proximity Sensor/Switch which is the most frequently used position/proximity sensor in many applications. Inductive proximity sensors can be ...

Proximity Sensor. A device that senses when another object is close by. In a mobile phone, a proximity sensor is most commonly used to detect when the phone is held to the face.
