MK Sensors
Ultrasonic Sensors (10 Amp)
MK Ultrasonic Sensors are a general purpose, fully automatic, directional presence detector with photocell.
The Ultrasonic Sensor saves energy by switching off lights in unoccupied areas and by holding lights off in
occupied areas that have adequate natural light.
MK Ultrasonic Sensors utilise ultrasonic radar to monitor a
space for movement. This involves transmitting an ultrasound
signal and examining the reflected signal for frequency
variations. Directional range of 13m makes the Ultrasonic
sensor ideal for use in corridors.

l
Ultrasonic radar monitors the controlled
space for movement, and is sensitive enough
to respond to even the slightest movement,
ensuring lighting is sustained whenever space is
occupied
l
If no movement has been detected for a pre-
selected period the lights will be switched off
until the next visitor is detected
l
Features movement detector, photocell and 10
Amp load switching element
l
Off delay adjustable between 5 and 15 minutes
following the last observed movement after
which the lights switch off
l
The adjustable photocell will bring lights on as
required if light levels in an occupied area fall
l
Two independent sensitivity controls make the
Ultrasonic Sensor extremely flexible in use
l
Adjustment controls are available for
commissioning purposes
l
‘On Range’ is the adjustable normal range
control
l
‘Off Delay’ sets the time delay after the last
detected movement
