Proximity sensor technology
Proximity sensors are inherently noncontact detection devices. Unlike traditional sensors that require a mechanical switch, lever, or plunger to be pushed against the moving target to adequately register the presence of an object, proximity sensors accurately detect an object without requiring contact. This noncontact design also protects the integrity of the sensor and promotes product quality by not subjecting sensing equipment or materials to unnecessary interaction.
Proximity sensors are designed to provide accurate and repeatable operation under high-speed conditions. Performing at speeds as high as 5,000 Hz, these sensors can easily accommodate the demands of many fast-paced industrial applications. Because their accuracy can be calculated to within 0.001 in., proximity sensors offer the precision necessary to maintain efficient, effective production.
Today’s proximity sensors are durable and flexible. Sensors are typically available with multiple IP ratings, which range from relatively clean environments to those with washdown conditions or temperature extremes. With various sizes, housings, and mounting options available, proximity sensors offer both versatility and application flexibility.
Performance versatility, application diversity
Different types of proximity sensors can solve a variety of sensing challenges. Using the right sensor for the right application minimizes downtime, reduces maintenance requirements, and enhances production efficiency. Understanding the various operating principles, performance capabilities, and application suitability of each proximity sensor type enables manufacturers to integrate the appropriate sensors to the right applications.
