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 non-contacting sensing
solution for absolute position sensing with enhanced accuracy.
It senses 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.
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
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 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.
With this sensor, Honeywell has utilized MR technology
through the ASIC at a level never before accomplished.
Other configurations are in development.
Accurate:
100° configuration accurately measures values
down to 0.06°while 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
