POWER OPERATED SLIDING GATE SOLUTION

Electric telescopic gate

Looking for a solution for electric telescopic gates?

Electric telescopic gates are widely used in industrial plants, warehouses, docks, aircraft hangars, and other places for import and export protection.Electric telescopic gates generally have the characteristics of flexible opening, large span, strong wind resistance, smooth operation, and not easy to damage. Electric telescopic gates generally achieve product safety by installing displacement sensors, infrared photoelectric sensors, and safety grating. By connecting the photoelectric sensor, when the door encounters a person or object obstruction during the closing process, the control system issues a control according to the signal transmitted by the sensor. Immediately open the door to prevent pinching events and machine damage phenomenon, and improve the safety and service life of the electric telescopic gate.

Safety Sensor Solutions for Electric Telescopic Gates：

Among the solutions for electric telescopic gates, the PMF55T through beam photoelectric sensors and LSE area detection light curtains are the most popular photoelectric sensors with excellent performance and high protection. Electric telescopic gates are commonly used to close industrial or residential areas and detect the passage of small cars and oversized vehicles in general. Electric telescopic gates are generally metal doors, and solid doors to enhance the wind resistance at the same time also for the entrance to pass increased security risks. The retroreflective photoelectric sensor has high accuracy and a long detection distance. Infrared grating products can achieve multi-point protection, and greatly enhance the scope of protection, in the electric telescopic gate security protection applications are increasingly popular.

What is a photoelectric sensor?

A photoelectric sensor consists mainly of a transmitter that emits light and a receiver that receives it. When the emitted light is interrupted or reflected by the sensing object, it changes the amount of light reaching the receiver. The receiver detects this change and converts it to an electrical output. Photoelectric sensors detect objects, changes in surface conditions, and other items through a variety of optical properties. The light source for most photoelectric sensors is infrared or visible light. Photoelectric switch transmitters mostly use semiconductor light-emitting diodes (LEDs) driven by narrow pulse currents at medium frequencies (around 40 kHz) as the light source to emit modulated light pulses. Accordingly, the output signal of the receiving photosensitive element (phototransistor) is processed by a 40kHz frequency-selective AC amplifier and a special demodulation chip, which can effectively prevent interference from sunlight, and fluorescent lamps, and can reduce the power consumption of the transmitting LED. The photoelectric sensor includes the through beam photoelectric switch, retroreflective photoelectric sensor, diffuse reflective photoelectric switch, slot photoelectric switch, and optical fiber photoelectric switch.

Electric cantilever sliding gate solution :

Electric cantilever sliding gates are widely used in residential communities, schools, factories, enterprises, and other public places. To ensure the safety of the import and export places, the electric cantilever sliding gate is usually installed with multiple sets of photoelectric sensors. And because the installation of sensors nearby will probably produce product crosstalk, which will lead to protection failure and other problems occur. Therefore, G-TEK has designed a frequency-selectable photoelectric sensor, PMF55T photoelectric sensor, specifically for the electric cantilever sliding gate. Simply replace the sensors installed side by side with PMF55T of different frequencies to completely solve the crosstalk problem. At the same time, the working principle of counter-lighting makes object detection more accurate. The detection distance is 60m, which can be adapted to most the electric cantilever sliding gates.

What are the characteristics of photoelectric sensors?

With the emergence and development of microelectronics technology, optoelectronic semiconductor technology, optical fiber technology, and grating technology, photoelectric sensor types are also increasing, photoelectric sensors are increasingly used. And photoelectric sensors have other sensors that can not replace the superiority, so it has great prospects for development. The physical basis of a photoelectric sensor is the photoelectric effect, it is composed of photoelectric material devices, both for the detection of non-electricity directly caused by changes in the amount of light, and also can be used to detect other non-electricity can be converted into changes in the amount of light. Photoelectric sensor mainly has six characteristics as can realize non-contact measurement, can realize color discrimination, can realize color discrimination, etc.
