INSTALLATION INSTRUCTIONS FOR THE
SMART POSITION SENSOR,
35 MM, 75 MM, 225 MM LINEAR
CONFIGURATIONS
GENERAL INFORMATION
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.
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.
MOUNTING AND WIRING INFORMATION
(see Figure 2)
-
Locate sensor and magnet in desired position. Ensure:
• Air gap between sensor and magnet does not exceed that given in Tables 1- 4 (depending upon model)
• Alignment of magnet along length of sensor does not exceed 2,0 mm ±2,5 mm [0.078 in ±0.098 in] from the center line of each component -
Mount sensor:
• Drill two holes, one for each mounting ear.
• Secure sensor using two 1/4-20 or M6 screws through each mounting ear
• Torque screws to 6 Nm to 10 Nm [53.1 in-lb to 88.5 in-lb] -
Mount magnet (Does not apply to 35 mm version.):
• Drill two holes:
– One for the single mounting ear
– One at 10,25 mm ±0.10 mm [0.403 in ±0.004 in] dia., and at least 3 mm [0.118 in] deep, for the mounting dog (helps stabilize magnet)
• While ensuring the mounting dog is seated in its hole, secure magnet using one 1/4-20 or M6 screw through the mounting ear
• Torque screws to 6 Nm to 10 Nm [53.1 in-lb to 88.5 in-lb] -
Wire sensor according to the lead colors given in the related figures. (Does not apply to 35 mm version.)
