Door Activation Sensor offer programmable operation.
April 29, 2008 - Employing swiveling optics to optimize threshold coverage, FLT-D triggers opening of automatic sliding doors when it detects approaching people and objects. Programming options include sensing area size, sensitivity to targets, synchronization to other FLT-D units, and frequency of automatic teaches. Able to monitor up to 20 sensing field segments by IR array, this IR photoelectric sensor learns and periodically re-learns its static environment automatically.
New Activation Sensor Provides Cost-Effective, Precise and Reliable Monitoring of Automatic Pedestrian Doors
TWINSBURG, OH - Pepperl+Fuchs introces the FLT-D infrared photoelectric sensor. Packaged in an inconspicuous and tamper-proof housing, the FLT-D provides reliable and affordable detection of approaching people and objects to trigger automatic sliding doors to open. Swiveling optics optimize coverage of the threshold so the sensing area can be close to the door. Programming options include sensing area size, sensitivity to targets, synchronization to other FLT-D units to cover larger thresholds, and the frequency of automatic teaches.
A single FLT-D sensor can monitor up to twenty different sensing field segments by an infrared (IR) array. It learns and periodically re-learns its static environment automatically, which can allow the sensor to "tune out" a stationary object such as a suitcase left in the area. At a mounting height of 7.2 ft (2.2 m), its factory default sensing field is 7.2 x 5 ft (2.2 x 1.5 m), and the sensing field can be customized for the application. The FLT-D complies with ANSI 156.10 2005 as an approach sensor.
Advantages of IR sensing over PIR (passive infrared) and microwave sensing include a more precisely defined sensing perimeter, and detection of a target&39;s absence or presence rather than just its movement. Additionally, IR-based sensors are not sensitive to temperature differentials as are PIR-based sensors.
