  • Old School Proximity Sensor Implementation
    Most inductive proximity sensors have a set of standardized behaviors and a designer's understanding of these behaviors can lead to successful implementation while avoiding the pitfalls typically associated with these sensors. Inductive proximity sensors generate a magnetic field from
  • 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
  • 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
  • Sensor Sense: Sensors and slag
    . It's not uncommon to find technicians replacing such sensors at the same location several times daily. Two factors bear heavily on how long a sensor lasts: the number of welds per hour and the sensor proximity to the welding. No question sensors used around welding must function in a harsh environment. Weld
