SR-ULM18-300NP-2M,Ultrasonic Proximity Switch
■ Compared with the proximity switch, the detection distance is
far, the volume is small, and the copper and aluminum are
non-ferromagnetic
materials can be stably detected
■ Compared with the traditional ultrasonic sensor, the blind area
within 300mm is small and the precision is repeated
The degree can reach the millimeter level
■ Compared with the photoelectric switch, it is completely
independent of the light transmittance, color, and external
environment of the object under test
Light, water mist, no fear of dust
■ Compared with capacitor switch, the detection distance is far,
the volume is small, and it is not subject to water and dust
Influence of
■ Tinned copper wire ensures good conductivity and
anti-interference ability.
And ensure the stripping operator's comfort, safety and no burrs
■ Own circuit board hardware and software, mold intellectual
property rights, can root
According to customer needs timely adjustment of product functions,
such as output: switch quantity
(PNP,NPN one), 4-20mA, 0-10VDV, 485, etc
■ Certified by professional organizations, with CE, ROHS

| Setting the switch point
The ultrasonic proximity switch has a switch output, put the
measured object in front of the sensor vertically (outside the
blind area, within the maximum detection range), press the button
and keep it for more than 2 seconds, if the yellow light flashes at
the frequency of 2Hz, release the button, and the current position
is saved, if the red light flashes at the frequency of 2Hz, the
target object is not detected. Adjust the target position or Angle
until the yellow light flashes. The current setting is valid.
The switch point can only be set after the power supply is
connected, and the detection distance should be set within 5
minutes of the sensor being powered on, otherwise the test cannot
be set. |
