  • Operating Principles for Capacitive Proximity Sensors
    Capacitive proximity sensors are used for non-contact detection of metallic objects & nonmetallic objects (liquid, plastic, wooden materials and so on). Capacitive proximity sensors use the variation of capacitance between the sensor and the object being detected. When the object is at a preset
  • Operating Principles for Inductive Proximity Sensors
    Inductive proximity sensors are used for non-contact detection of metallic objects. Their operating principle is based on a coil and oscillator that creates an electromagnetic field in the close surroundings of the sensing surface. The presence of a metallic object (actuator) in the operating area
  • Application: Door Sensor-Fire, Safety Exit (.pdf)
    to activate. the sensor. Features. · Alternative to inductive sensors. · One component reed sensor. · The reed sensor never comes in direct contact. with the movement of the door. · The reed switch used in the reed sensor is. hermetically sealed and is therefore not. sensitive to dirty environments
  • Sensors 101: Baumer Electric Basics
    Inductive sensors are non-contact proximity sensors designed to detect the presence or absence of a ferrous material, the ideal target being mild steel at least 1 mm thick and the same diameter as the sensing face. Inductive sensors consist of four major components: a ferrite core with coil
  • Mounting Flexibility with a Factor 1 Sensor (.pdf)
    Traditional inductive proximity sensors are designed for wear-free and non-contact detection of metal objects. The sensor consists of a coil and ferrite core arrangement, an oscillator and detector circuit, and a solid-state output. They operate with a highfrequency electromagnetic field
  • Understanding Factor 1 sensors: When and where to use
    Non-contact proximity sensors can improve the ruggedness of manufacturing operations, such as metal component assembly, by replacing delicate mechanical switches. Sensor selection for these applications is based on several factors, including the types of metal to be detected, information required

Normally Open Reed Switch. and for that reason have attracted the interest of power efficient. designers. Latching Reed Switches and sensors
  • Capacitives with Perspective
    Unlike inductive proximity switches, which respond exclusively to metals, capacitive sensors react to a wide spectrum of other materials, such as for example: paper, glass, plastics, oil, water, as well as all metals. The sensor output switches when the object to be detected is within a certain
