  • White Paper: Do You Know When Your Proximity Sensor is Sick?
    A proximity sensor is a sensor capable of detecting the. presence of nearby metal objects without any physical. contact. The proximity sensor generally functions. by detecting changes in a local electromagnetic. field. This field could be emitted by the proximity. sensor itself, or by the metal
  • Proximity Sensors
    Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target. Different targets demand different sensors. For example, a capacitive or photoelectric sensor might
  • Proximity sensors for stamping dies
    Difficulties that plague die-stamping operations include overfeeds, underfeeds, slugs, and missed hits. This flat-pack proximity sensor tells a controller that the die has closed properly. A spacer plate under the sensor raises it to the correct detection height for this die. Proximity sensors head
  • Eliminated the Need for the Intermediate Actuator by Replacing Proximity Sensors
    How to detect workpieces made from various kinds of materials without installing an intermediate actuator onto a proximity sensor? By replacing it with Metrol "High-precision Positioning Switch" which directly touch the workpieces, reliable detection as well as cost reduction and space saving can
  • Application: Convertible Roof Limit Position Sensor (.pdf)
    Convertible roof position whether open or closed require a magnetic proximity sensor to turn off the roof motor. The reed sensor can reliably sense both end positions and activate or deactivate the motor.
  • Proximity Sensing in Washdown Environments (.pdf)
    Damp or humid industrial environments, or those that require frequent washdowns by water, foam or cleaning/disinfecting agents, produce adverse conditions for proximity sensors. It takes more than a run-of-the-mill sensor to withstand the rigors of these environments, commonly found in food
  • 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
