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 certificate

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.
