SICKUb180-2n41137It is a product based onThrough beam photoelectric detection principleThe M18 cylindrical sensor belongs to the V180-2 series. It is known for itsLong detection distance, high response speed, and reliable industrial adaptabilityWidely used in automation fields such as logistics, packaging, and material handling.
1、 Detailed explanation of application principles
Its core working principle isOptical path obstruction detection.
-
System CompositionSensors are composed ofTransmitterandReceiverComposed of two independent units. The receiver model of VSE180-2N41137 is VSE180-2N41137, and the transmitter is usually the matching VSE180-2E41137.
-
workflow:
-
launch: Inside the transmitterRed visible light LED(wavelength 645nm) emits a modulated beam of light.
-
transmissionThe light beam propagates in the air, and the effective detection distance can reach28 metersThe standard sensing distance is20 meters.
-
receiveThe receiver continuously receives optical signals from the transmitter.
-
Judgment and outputWhen the object under test enters the optical path between the transmitter and receiver, andBlock the beam of lightWhen the receiver detects a significant change in light intensity. The internal circuit converts this change into an electrical signal and alters itNPN type switch outputThe state (e.g. changing from "open" to "closed").
-
signal indicationOn the sensor housing360 ° visible LED indicator lightIt will light up (usually orange or green) to visually display the output status and signal strength, making it easy to debug and diagnose.
Technical features support its application:
-
Long distance and high precisionA detection distance of 28 meters and a fast response time of ≤ 0.5ms, suitable for object detection and counting on high-speed assembly lines.
-
Strong anti-interference abilityThe principle of reflection makes it almost unaffected by the color, material (opacity is sufficient), and surface reflectivity of the object being tested, making the detection very reliable.
-
environmental adaptability:IP67 protection levelIt can prevent dust and water, and withstand vibrations and heat in industrial environments.
-
Flexible settings: On the receiver270 ° sensitivity adjustment potentiometerThe trigger threshold can be finely adjusted to adapt to different media transparency or environmental light interference.
2、 Installation and Debugging Steps Guide
Proper installation and debugging are key to ensuring the stable operation of sensors.
Step: Installation preparation and mechanical fixation
-
Paired use: EnsureTransmitter (E)andReceiver (N)Used in conjunction with.
-
relative installationOn both sides of the detection path, use the providedM18 × 1 fixing nutAlign the transmitter and receiver for installation. Ensure bothStrictly align the optical axis(i.e. aligning the center of the transmitter's light spot with the center of the receiver's receiving window).
-
Installation spacingBased on the actual size and position of the detected object, set the distance between the two at0-20 metersWithin the sensing distance, with a certain margin left.
-
Environmental avoidanceAvoid installing sensors in areas withRigid light emission(such as sunlight, welding arc)A large amount of dust, water mist or strong vibrationThe location. If it needs to be used in harsh environments, consideration should be given to installing protective covers.
Step 2: Electrical wiring
-
power supplyConnect the transmitter and receiver separately10-30V DCPower supply, pay attentionpolarity(Usually the brown wire is connected to+24V, and the blue wire is connected to 0V). The sensor has reverse polarity protection, but incorrect wiring may cause it to malfunction.
-
Output connection: Receiver'sBlack line (output line)Connected to PLC or controllerDigital input pointAs it is an NPN output, the load should be connected between the output terminal and the positive terminal of the power supply (i.e. the output is at a low level).
-
Functional LineWhite lines are usually used forLight ON/Dark ONMode selection, please refer to the product manual for details.
Step 3: Beam Alignment and Debugging
-
Preliminary alignmentAfter power on, the red LED of the transmitter will remain on. Observe with the naked eye or use a piece of white paper as an aid, roughly adjust the angle between the two to make the receiverGreen Stability LEDBrightest or constantly on indicates good signal.
-
fine-tuning:
-
Slowly rotate the receiverSensitivity adjustment potentiometerUntilOrange action indicator light (OUTPUT LED)Just extinguished (when there is no object obstruction).
-
At this point, if an object is detected to obstruct the light path, the orange indicator light should light up and the output signal should switch.
-
If the indicator light does not turn off after the object is moved away, it indicates that the sensitivity is too high, and the potentiometer needs to be adjusted counterclockwise to reduce the sensitivity. On the contrary, if the indicator light does not light up after being blocked, the sensitivity needs to be increased clockwise.
-
Mode SettingsAs needed, set the output logic toBrightpass(Output when there is light) orDark Pass(Output when blocked from light).
Step 4: Testing and Validation
-
Let the tested object pass through the detection area multiple times at its actual operating speed, and observe whether the output indicator light and PLC input point signal are correctStable and without omissions.
-
Check if the output remains stable, without flickering or false triggering when no object passes through.
Important precautions
-
safetyBefore installation and debugging, please ensure that the equipment is powered off.
-
Full range useFor long-distance detection, try to make the transmitter and receiver as close as possibleProximity sensing distanceWork on the position to obtain signal-to-noise ratio.
-
regular maintenanceMaintain transmitter and receiverLens surface cleaningTo avoid dust and oil stains affecting the light transmittance.
