Inductive proximity sensor

  1. 1. INDUCTIVE PROXIMITY SENSOR GROUP MEMBER: Muhammad Ikhwan Solehin b. Azmi Muhammad Aizuddin b. Abbas Akmal Hakim b. Ahmad 1
  2. 2. DEFINATION  Proximity sensors detect the presence of objects without physical contact. Since 1983 Fargo Controls’ proximity sensors have been of the highest quality, durability & repeatability to meet today's tough industrial requirements.  Typical applications include the detection, position, inspection and counting on automated machines and manufacturing systems. They are also used in the following machinery: packaging, production, printing, plastic moulding, metal working, food processing, etc.  Inductive proximity sensors are electronic device that detect metal object. 2

  18. 18.  Miniature inductive proximity sensors with threaded and smooth tubular. Sensing ranges up to 5mm, non-flush.  Inductive proximity switches in industry standard housings, with sensing ranges up to 15mm, non-flush.  Small rectangular proximity sensors for applications with limited mounting space.  Large rectangular inductive proximity switches with sensing ranges up to 40mm, non-flush.  Ring and tube inductive sensors for detecting small parts in plastic tubing. 18
