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 noncontacting sensing solution for absolute position sensing with enhanced accuracy. It senses the position of a magnet relative to the sensor in one of three available sensing ranges:
• 0 mm to 35 mm [0 in to 1.38 in]
• 0 mm to 75 mm [0 in to 2.95 in]
• 0 mm to 225 mm [0 in to 8.86 in]
These sensors uses a patented combination of an ASIC (ApplicationSpecific 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 object's position can be determined or controlled.
The MR array measures the output of the MR sensors mounted along the magnet's direction of travel. The output and 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.
The SMART Position Sensor is available in both analog output (35 mm, 75 mm and 225 mm configurations) and digital output (225 mm configuration only) for use in control systems requiring an RS232-type interface with a 57.6 kbits/s baud rate.
FEATURES
• Reliable: Non-contact design reduces wear and tear, improving reliability and durability, and minimizing downtime
• Installation takes four simple steps (1: position sensor; 2: drill holes; 3: mount sensor; 4: locate magnet actuator/ make electrical connection)
• Rugged: As there are no moving parts within the sensor, Honeywell utilizes unique packaging materials that make the sensor more resistant to vibration, shock, and extreme temperatures
• Air gap of up to 8,5 ±1,0 mm [0.334 ±0.039 in] between sensor and magnet expands application opportunities; variety of output options (analog standard and other RS232-type baud rates) are available, expanding application opportunities
• Accurate: 35 mm configuration accurately measures values down to 0,04 mm [0.0016 in], 75 mm configuration accurately measures values down to 0,05 mm [0.002 in], while 225 mm configuration accurately measures value down to 0,14 mm [0.0055 in] (analog) and 0,0035 mm [0.000137 in] (digital)
• Adaptable: Electronics on board allow for flexible packaging and component compatibility with existing systems
• More than 50% lighter in weight than LVDT (Linear Variable Differential Transformer) technology
• Easy-to-configure sensor array fits virtually any linear movement path
• Self-diagnostics feature can reduce equipment downtime by providing predictive maintenance input
• IP67 and IP69K sealing allows use in many harsh applications
• Qualified for automotive grade EMI/ EMC specification provides protection against environmental frequencies (35 mm configuration only)
• RoHS-compliant materials meet Directive 2002/95/EC
POTENTIAL APPLICATIONS
(May not apply to all configurations.)
• Industrial: Valve position, Material handling, plastic molding, cutting and slitting, wafer handling, CNC machines
• Transportation: Engine transmissions, passenger bus level position, truckmounted crane outrigger position, heavy equipment attachment identification, hydraulic cylinders, marine motors
• Aerospace: Aircraft actuators
