description the smart position sensor is one of the most durable, adaptable, and lightweight linear position sensors available in the industry, enabling highly accurate motion control and improving operation efficiency and safety. its simple, non- contact design eliminates mechanical failure mechanisms, reducing wear and tear, improving reliability and durability, and minimizing downtime. the smart position sensor is a n on -contacting sensing solution for absolute position sensing with enhanced accuracy . it se nses the position of a magnet relative to the sensor in one of two available sensing ranges: 0 to 100 0 to 180 why is the smart position sensor smart? smart means that this is a sensor that can essentially think for itself. smart position sensors provide a self-diagnostics feature and data gathering for enhanced reliability and closed-loop feedback control. they use a patented combination of an asic (application- specific integrated circuit) and an array of mr (magnetoresistive) sensors to accurately and reliably determine the position of a magnet attached to a moving object so that the objects position can be determined or controlled. the mr array measures the output of the mr sensors mounted along the magnets direction of travel . the output a nd the mr sensor sequence determine the nearest pair of mr sensors to the center of the magnet location. the output of these two mr sensors is then used to determine the position of the magnet between them. with this sensor, honeywell has utilized mr technology through the asic at a level never before accomplished. other configurations are in development. value propositions ( ? = competitive differentiator) ? reliable, durable: non-contact design reduces wear and tear, improving reliability and durability, minimizing downtime ? easy to install: installation takes 4 steps (1: position device; 2: drill holes 3: mount sensor; 4: locate magnet/connect sensor) vs. up to 14 steps some competitive products require, simplifying installation and reducing set-up costs rugged: as there are no moving parts within sensor, honeywell utilizes unique packaging materials that make it resistant to vibration, shock, and extreme temperatures ? flexible: air gap tolerance of 7,8 2,5 mm [0.307 0.098 in] (100 ) and 8,5 2,5 mm [0.338 0.098 in] (180 ) between sensor and magnet expands application use ? cost effective: adaptable, non-contacting design allows customers to eliminate unnecessary connections for installation, thereby reducing installation steps/time and components accurate: 100 configuration accurately measures values down to 0.06while the 180 configuration accurately measures values down to 0.11 ? adaptable: electronics on board allow for flexible packaging and component compatibility with existing systems ? lightweight: lighter in weight than optical encoders ? self-diagnostics feature can reduce equipment downtime by providing predictive maintenance input combined patented mr sensor and asic technology provides enhanced differentiation and performance ip67, ip69k sealing allow use in many harsh applications rohs-compliant materials meet directive 2002/95/ec
