Product is not recommended for applications exposed to children.

• The SENSOR is designed to detect iron-
based metal in motion.
• The SENSOR’s ability to detect iron-based
metal objects is based on the mass, velocity
and proximity of the object to the sensor.
EXAMPLE - A child’s bicycle moving at
2 mph @ 1’ from the sensor has a similar
effect as a car moving at 2 mph @ 6’ from
the sensor.
• The SENSOR must be stationary to function
properly.
