Safety Optical Through Beam Sensor for Tripod Turnstile with CE Certificate

Product DescriptionPM18 series proximity sensor is one metal shell cylindrical photocell sensor; It includes a through-beam type, polarized reflective type, and diffused type.PM18T opposed type photoelectric sensor is our most popular model used at turnstiles. PM18T photoelectric sensor installed at the turnstile gate entrance is used to detect whether people intrude into the turnstile gate. When swiping the card outside the yellow line, there is no object at the gate entrance, and the sensor signal is standard, the wing door will open; if the person goes inside the yellow line, the sensor signal at the gate entrance changes, even if swiping the card, the wing door will not open. The purpose of this design is to prevent the opening and closing of the wing gate when swiping the card at a short distance, which may cause potential safety hazards, and also prevent ticket evasion.

Detect whether the installation position of the object and the proximity sensor has deviated, slack, or skewed; whether there is slack, poor contact, or disconnection in the wiring and connection parts2. Whether there is adhesion or accumulation of metal dust, etc.3. Is there any abnormality in using temperature conditions and environmental conditions?4. Set whether the flashing of the display lamp type is abnormal.If you must be careful not to disassemble and repair by yourself during the inspection, and to easily find out the fault, you can investigate the operating state of the sensor through the connection with the portable detector, and then repair it according to the situation.In order to make the photoelectric sensor work stably for a long time, it should be regularly checked with the same contents as the general control equipment to maintain its long-term function. The photoelectric sensor can also be stocked. Once a problem with the photoelectric sensor is found, we can replace it in time without affecting the use of the sensor.What is a photoelectric sensor?Photoelectric sensors, also known as photo eyes, emit a beam of light that is used to detect the presence or absence of items and equipment or changes in surface conditions. When the emitted light is interrupted or reflected by the object, the change in light patterns is measured by a receiver and the target object or surface is recognized. Photoelectric sensors are very common in industrial manufacturing, such as material handling, packaging, food and beverage, medical, and many others.Depending on the style selected, they can be used with or without a reflector, and be self-contained, long-range, heavy-duty, or compact. There are much different housing and mounting options to offer a correct fit that meets the demands of each application. They perform a wide variety of tasks and some of them can even be used in harsh environments.   Company ProfileTianjin G-TEK sensor technology co..ltd is indicated in providing intelligent sensor products and customized solutions for logistics automation, factory automation and process automation.
