Proximity sensors.<\/p>\n\n\n\n<p>Proximity sensors are capable of detecting the presence of a target without contact. Having no part contact tied with no moving parts means higher durability and reliability with reduced maintenance and downtime.<\/p>\n\n\n\n<p>In this guide, we\u2019ll focus on <a href=\"https:\/\/us.misumi-ec.com\/vona2\/mech\/M0400000000\/M0401000000\/M0401030000\/M0401030100\/?curSearch=%7b%22field%22%3a%22%40search%2cseriesList.templateType%22%2c%22categoryCode%22%3a%22M0401030100%22%2c%22sort%22%3a1%2c%22allSpecFlag%22%3a0%2c%22page%22%3a1%2c%22brandModeFlag%22%3a1%2c%22pageSize%22%3a45%2c%22unitType%22%3a%221%22%7d&amp;listDisplay=mc-list\">inductive and capacitive proximity sensors<\/a>, which are available through MISUMI.<\/p>\n\n\n\n<h2>Inductive Proximity Sensors<\/h2>\n\n\n\n<p>Much like a mini metal detector, an <a href=\"https:\/\/us.misumi-ec.com\/vona2\/mech\/M0400000000\/M0401000000\/M0401030000\/M0401030100\/?curSearch=%7b%22field%22%3a%22%40search%2cseriesList.templateType%22%2c%22categoryCode%22%3a%22M0401030100%22%2c%22sort%22%3a1%2c%22allSpecFlag%22%3a0%2c%22page%22%3a1%2c%22brandModeFlag%22%3a1%2c%22pageSize%22%3a45%2c%2200000029380%22%3a%22a%2cb%22%2c%22unitType%22%3a%221%22%7d&amp;listDisplay=mc-list\">inductive proximity sensor<\/a> detects metallic objects by using electromagnetic induction. This means that the sensor gives off a magnetic field that creates electrical currents within the conductive target, also known as &#8220;eddy currents.&#8221; These currents cause a magnetic loss, and it\u2019s this change that triggers the sensor.<\/p>\n\n\n\n<p>These sensors are best used in applications where the target is made of a metallic material. The aforementioned metal detector is a good example of durability due to being a tool typically used outdoors in water or in coarse, rough, and irritating sand that gets everywhere.<\/p>\n\n\n\n<p>For more of an automated environment, these sensors perform well in part detection applications where accessibility is difficult and won\u2019t trigger if covered in water or oil.
