DESCRIPTION
The SMART Position Sensor, 75 mm linear configuration, is a
non-contacting sensing solution for linear absolute position
sensing with enhanced speed and accuracy. It senses the
position of a magnet relative to the sensor from 0 mm to
75 mm [0 in to 3.0 in].
Why is the SMART Position Sensor smart? SMART means
that this is a sensor that can essentially think for itself. The
SMART Position Sensor has the ability to self-calibrate
because it uses 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
(e.g., elevator, valve, machinery, etc.) so that the object’s
position can be determined.
FEATURES
Resolution of up to 16 bits provides enhanced accuracy
Non-contacting technology can provide enhanced product
life and durability with less downtime
Combined patented MR sensor and ASIC technology
provide enhanced differentiation and performance
Air gap of up to 3,0 ±2,5 mm [0.118 ±0.098 in] between
sensor and magnet expands application opportunities
Other output options (CAN bus, RS232) available upon
request
Self-diagnostics feature can reduce equipment downtime
Small size, taking up less space than most competitive
technologies, allows for use where space is at a premium
IP67 and IP69K sealing allow use in a variety of harsh
applications
RoHS-compliant materials meet Directive 2002/95/EC
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.
With this sensor, Honeywell has utilized MR technology
through the ASIC at a level never before accomplished.
Other configurations are in development.
