Sensor Trends

Because of certain drawbacks of physical contact style sensors and switches such as limit switches and float switches, newer technology non-contact style sensors have become prevalent in industry, performing well in many applications. Proximity, photoelectric and ultrasonic sensors can be used in many applications for which they were previously never considered. These non-contact sensors are…

New Spherical Optics Technology for Sensing in Small Areas

The Challenge Diffuse sensors enjoy great popularity with users. With diffuse sensors, pulsed light from an emitting diode falls on an object of any shape or color and is reflected in a diffuse manner to a light-receiver, which is located in the same device (fig.1). If the intensity of the received light is sufficient, the…
