Application
Hand-‐E-‐Wave is a touchless microwave switch designed to provide a DPDT
relay normally open or normally closed output when motion is detected
within the detection zone. The switch can be configured to provide a 1 to
30 second timed output or a toggle (on/off) output.
Powering the Unit
Hand-‐E-‐Wave is powered with an un-‐switched 12 to 24VAC/DC.
Polarity
need not be followed; the switch will work, as long a there is a correct
voltage across the red & black wires. This input voltage cannot be in series
with any connected locking mechanism, such as magnetic locks, etc..
Operate the Sensor
Move your hand within the detection zone to activate the sensor. The “Hand” symbol will change from Blue to Green and the
audio will beep (if audio is enabled) to indicate successful activation of the sensor and relay.

Detection Zone
Hand-‐E-‐Wave’s detection zone may be adjusted from 2” to 24” (typical). Locate the
Detection Zone
potentiometer and rotate
with a small standard screwdriver clockwise to increase the sensing field. Rotate counter clockwise to decrease the sensing
field. Use a greater range setting for an application where there is little traffic, and precision is not required. Caution should be
taken where the door may move into the beam when closing or operating, as this may also activate the sensor. Use a shorter
read range for an application where a positive deliberate wave is used to activate.
Output Mode
Timed Mode
is recommended for applications where a momentary or timed output is desired. In Timed mode, detection activates
the relay for a set period of time (0.5 to 30 seconds) while there is movement in front of the sensor. To select timed mode,
remove the
Output Mode
jumper (or place the jumper over ONE pin). To
SET
the output time, locate the
Output Time
potentiometer and rotate clockwise to increase the output time (up to 30 seconds). Rotate counter clockwise to decrease the
output time. To trigger an automatic door opener, set the output time to 1 second. Adjust this time so that the door would
remain unlocked from activation to egress.
Toggle Mode
is recommended for ON/OFF switch applications. In toggle mode, detection activates the relay and a second
detection deactivates the relay. To select toggle mode, place the jumper over BOTH pins of the
Output Mode
.
Audio Control
Hand-‐E-‐Wave’s audio feedback occurs when motion is detected within the detection zone. Audio can be enabled or disabled. To
enable audio feedback, remove the
Audio Control
jumper (or place the jumper over ONE pin). To disable audio feedback, place
the jumper over BOTH pins of the
Audio Control
.
