Proximity Sensing with CapSense ®. 1 Introduction. A proximity sensor detects the presence of a nearby object without any physical contact. There are various types of proximity sensors such as capacitive, inductive, magnetic, Hall effect, optical, and ultrasonic sensors, each of which has its own
OPTICAL PROXIMITY SENSORS: An optical proximity sensor offers non-contact sensing of almost any object up to a range of 10 meters. It includes a light source, (usually an LED in either infrared or visible light spectrum) and a detector (photodiode). The light source generates light of a frequency
Position sensors are used in a wide range of automation and measurement applications. A key step in selecting a suitable position sensor is understanding the requirements of sensor size, resolution, repeatability, accuracy, mounting constraints and environmental ruggedness.
Inductive Proximity. Sensor Accessories. Photoelectric. Ultrasonic. Optical Encoders. Laser Marking Systems. The inductive proximity sensors belonging to the Basic line were made in the classic cylindrical nickel-plated brass, with diameters ranging from 6.5 to 30 mm.

The Proximity Sensor extends the Generic Sensor API [GENERIC-SENSOR] to provide information about proximity level, as detected by the device’s primary proximity sensor. The proximity level is reported as the distance (in centimeter) from the sensor to the closest visible surface. § Optical sensors are extremely versatile, due to the rapid development of photoelectric technology. This versatility allows them to solve the bulk of the industrial proximity sensing needs1. Such needs include sensing of metallic or non-metallic objects, very small objects, over long distances, and with fast
Inductive Proximity Sensors are durable. For example, all KEYENCE sensor head models satisfy the IP67 requirements by sealing the inside with filling material or other measures. Two-wire type inductive proximity sensors allow simplified wiring and can be used for both NPN and PNP circuits.
