Create a huge presence. Ultrasonically senses distances of objects, persons,
walls from 0.15 to 12 m (0.49 to 39 ft.). Is invisible to the audience.
Not suitable for low volume sound installation. For a silent distance sensor that measures upto 6.45 m (21.2 ft.) try the Advance-645.
Application examples
- Use for distance measurement relative to a wall or presence detection of objects and persons
(it cannot detect the number of people present).
- Combine with a
TapTiled floor,
some MoveOn
and/or ReachClose
sensors and make sure every move of your visitor has an effect.
Perhaps the TouchStripOn
is useful for additional coverage on walls.
The Flash +
SeeLaser
combo allows you to implement break-beams that could indicate borders or thresholds.

Weight |
150 g (5.3 oz), incl. cable |
Cable |
5.0 m (16 ft), shielded, red wire = power, uninsulated wire = ground, black wire = sensor output, maximum extension 25 m (82 ft) |
Connector |
male plug with a row of 3 pins spaced 2.54 mm (0.100 inch) |
Application notes |
- multiple FarReach sensors can be placed adjacently where the spacing is determined by the maximum distance to be measured at which distance the ultrasound emission cones should not overlap
- any indirect echoes of the ultrasonic pulse (eg. from the sidewalls in a narrow corridor) may generate incorrect sensor output values
- not suitable for low volume sound installations due to ultrasonic pulse which is audible as a click
- do not connect the FarReach plug reversely to the Digitizer, because it might blow the fuse in the Digitizer !
