SMART Position Sensor,
100 and 180 Arc
Configurations
DESCRIPTION
The Honeywell SMART Arc Position Sensor is one of the most
durable, adaptable, lightweight, and non-contact position
sensors available, enabling absolute position sensing with
enhanced accuracy. This simple, robust, arc position sensor
offers an IP69K sealed package, eliminating mechanical failure
mechanisms, reducing wear and tear, improving reliability and
durability, and minimizing downtime.
The SMART Arc Position Sensor is a non-contact sensing
solution, providing highly accurate motion control and
improving operation efficiency and safety. This Honeywell
position sensor utilizes magnetoresistive technology to detect
the position of a magnet relative to the sensor in one of two
available sensing ranges:
0º to 100º
0º to 180º
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.
These devices 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.
VALUE PROPOSITIONS ( = competitive differentiator)
 Reliable, durable: Non-contact design reduces wear and
tear, improving reliability and durability, minimizing
downtime
 Easy to install: Installation takes four 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: Honeywell utilizes unique package materials
with no moving parts within the sensor, making it resistant
to vibration, shock, and extreme temperatures
 Flexible: Air gap tolerance of 7,8 ±2,5 mm [0.307
±0.098 in] or 9,2 ±2,5 mm [0.36 ±0.09 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, reducing installation steps/time and
components
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
provide enhanced differentiation and performance
IP67, IP69K sealing allow use in many harsh applications
RoHS-compliant materials meet Directive 2002/95/EC
