Finder Adds 3 New Application-Specific Movement Detectors to its 18 Series Range

Finder.jpg
Based on new innovative electronics and optics Finder has added 3 new application-specific movement detectors to its 18 Series range.

Specifically for sensing within larger rectangular areas such as hotel lobbies and long corridors, the 18.41 surveys an area up to 15 metres either side of the device, giving an extensive total detecting zone of 30 metres long by 4 metres wide, from just a single unit.
 
Central to the 18.51 is an advanced lens and electronics system that achieves two detecting zones with different sensitivities. The central 4 x 4 metre zone responds to very small movements, able for example to pick-up on the presence of a person quietly working at his workplace. But additionally, within an extended 8 x 8 metre zone, it will also respond to normal movements. This product is particularly targeted at offices, schools, and the workplace in general.
 
“Twin-Mirror” technology gives the 18.61 its exceptionally wide viewing angle of 180°. Specifically designed for fitting into new or existing wall boxes, the 18.61 can be installed in corridors along with the 18.41 but is equally suited to small spaces such as bathrooms or passage areas. Essentially it can be installed as a direct replacement for a wall mounted light switch or push-button.
 
All three models share the common characteristics of a wide 110 … 230 V AC power supply range, a 10A rated NO output contact, adjustable ambient light intervention threshold and a Light-Off delay adjustable from 12 to 35 minutes.
 
Depending on the type, these new products can be installed on the ceiling, in suspended ceilings or in recessed or flush mounting boxes.

Why is the SMART Position Sensor smart? SMART means that this is a sensor that can essentially think for itself. With the SMART position technology, Honeywell has utilized MR (magnetoresistive) technology through the ASIC (Application-Specific Integrated Circuit) at a level never before accomplished. The rotary configuration joins Honeywell’s SMART Position Sensor family of proven linear and arc configurations.

The SMART Position Sensor, Rotary Configuration, 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 a range of 0º to 360º.

Honeywell uses a patented combination of an ASIC and an array of MR sensors to accurately and reliably determine the position of a magnet collar attached to a rotating object so that the object’s position can be determined or controlled. 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.

The SMART Position Sensor, Rotary Configuration, fits on a 25,4 mm [1 in] shaft. A mounting tool fixture (purchased separately) provides repeatable installation.

Value Propositions
*  Non-contact design: Eliminates mechanical failure mechanisms, reducing wear, which improves reliability and durability, and minimizes downtime
