SMART Position Sensor, 35 mm, 75 mm and 225 mm Linear Configurations Superior Measurement. Accurate. Reliable. Thinking. DESCRIPTION The SMART Position Sensor is one of the most durable, (magnetoresistive) sensors to accurately and reliably determine adaptable, and lightweight linear position sensors available in the the position of a magnet attached to a moving object so that the industry, enabling highly accurate motion control and improving objects position can be determined or controlled. operation efficiency and safety. Its simple, non-contact design The MR array measures the output of the MR sensors mounted eliminates mechanical failure mechanisms, reducing wear and along the magnets direction of travel. The output and the MR tear, improving reliability and durability, and minimizing downtime. sensor sequence determine the nearest pair of MR sensors to The SMART Position Sensor is a non-contacting sensing solution the center of the magnet location. The output of these two MR for absolute position sensing with enhanced accuracy. It senses sensors is then used to determine the position of the magnet the position of a magnet relative to the sensor in one of three between them. available sensing ranges: With this sensor, Honeywell has utilized MR technology through 0 mm to 35 mm 0 in to 1.38 in the ASIC at a level never before accomplished. 0 mm to 75 mm 0 in to 2.95 in The SMART Position Sensor is available in both analog output 0 mm to 225 mm 0 in to 8.86 in (35 mm, 75 mm and 225 mm configurations) and digital output These sensors uses a patented combination of an ASIC (225 mm configuration only) for use in control systems requiring (Application-Specific Integrated Circuit) and an array of MR an RS232-type interface with a 57.6 kbits/s baud rate. FEATURES AND BENEFITS Accurate: 35 mm configuration accurately measures values Reliable, durable: Non-contact design reduces wear and tear, down to 0,04 mm 0.0016 in , 75 mm configuration accurately improving reliability and durability, and minimizing downtime measures values down to 0,05 mm 0.002 in , while 225 mm Easy to install: Installation takes four simple steps configuration accurately measures value down to 0,14 mm (1: position sensor 2: drill holes 3: mount sensor 4: locate 0.0055 in (analog) and 0,0035 mm 0.000137 in (digital) magnet actuator/make electrical connection) vs. up to 14 steps Adaptable: Electronics on board allow for flexible packaging some competitive products require, simplifying installation and and component compatibility with existing systems reducing set-up costs Lightweight: More than 50% lighter in weight than LVDT Rugged: As there are no moving parts within the sensor, (Linear Variable Differential Transformer) technology Honeywell utilizes unique packaging materials that make Simplifies design-in: Easy-to-configure sensor array fits the sensor more resistant to vibration, shock, and extreme virtually any linear movement path temperatures Self-diagnostics feature: Can reduce equipment downtime by Flexible: Air gap of up to 8,5 1,0 mm 0.334 0.039 in providing predictive maintenance input between sensor and magnet expands application opportunities Combined patented MR sensor and ASIC technology: variety of output options (analog standard and other RS232- Provides enhanced differentiation and performance type baud rates) are available, expanding application IP67 and IP69K sealing: allow use in many harsh applications opportunities Qualified for automotive grade EMI/EMC specification: Cost effective: Adaptable, non-contacting design allows Provides protection against environmental frequencies (35 mm customers to eliminate unnecessary connections for configuration only) installation, thereby reducing installation steps, installation time, RoHS-compliant materials: Meet Directive 2002/95/EC and componentsSMART Position Sensor POTENTIAL APPLICATIONS (Applies to all configurations except where noted.) INDUSTRIAL AEROSPACE Valve position: May be used to monitor valve position so the Aircraft actuators: May be used to control actuator position on desired amount of liquid is delivered based on the position of multiple applications in the aircraft, helping to regulate airflow to the valve that is opening/closing, and how long open/closed engines and environmental systems. (e.g., bottling machines, food/chemical processing, water handling equipment, etc.). Material handling: May be used on a lifting device that moves cartons from one conveyor belt to another. Plastic molding: May be used for injection positioning. Cutting and slitting: May be used in paper mills to accurately control the location of the slitter before it cuts. Wafer handling: May be used to monitor if parts are properly placed. CNC machines: May be used to monitor tool depth and direction of travel. TRANSPORTATION Engine transmissions: May be used for gear shift position for trucks (35 mm configuration only). Passenger bus level position: May be used for passenger bus leveling to simplify access for passengers and luggage. Truck-mounted crane outrigger position: May be used to determine that the outriggers are fully deployed before the lifting of objects can begin. Heavy equipment attachment identification: May be used to sense which attachments are being deployed onto heavy equipment by the strategic placement of the magnet to the sensor. The corresponding output indicates to the operator and control system which attachment is connected. Hydraulic cylinders: May be used on non-ferrous hydraulic cylinders for non-contact stroke position (225 mm configuration only). Marine motors: May be used for trim position on inboard/ outboard motors for enhanced durability and performance. 2 Honeywell Sensing and Control
