Proximity Sensors

htm-web-banner-prox-765.png

HTM Sensors features an exceptionally comprehensive line of industrial inductive proximity sensors engineered to handle both standard general purpose automation and the most demanding factory floor environments. Their product line ranges from highly economical, standard-range general purpose proximity sensors in M8, M12, M18, and M30 form factors to ultra-rugged, specialty sensors designed to mitigate unexpected downtime and minimize availability losses. For severe physical-impact environments like heavy industrial manufacturing and robotic assembly lines, HTM provides extended, and long range sensors built out of a single piece of solid titanium—as well as their MetalHead™ line, which incorporates a robust, one-piece stainless steel face to protect the internal electronics. Furthermore, they accommodate harsh processing applications by offering specialized configurations including Weld Field Immune and SpatterGuard™ models equipped with Polytetrafluoroethylene (PTFE), and ceramic coatings to repel weld spatter, high temperature electronics for furnace monitoring, ring sensors, and advanced IO-Link models designed for bidirectional smart factory connectivity. Backed by lifetime warranties on their standard models and substantial inventories for same-day shipping, this comprehensive portfolio provides an efficient alternative for direct industry cross-referencing, delivering high environmental immunity and enhanced lifecycle reliability at a lower operating cost.
