Product Installation & Maintenance
Product installation:
The installation of the photoelectric sensor is relatively simple, as long as the sensor is installed on the fixing frame, does not be blocked by other things, and ensures the working state is good.
Product maintenance:
Carry out regular inspections to check its sensitivity and some relatively safe measures. The use of these measures is also the most primitive function of our equipment for protection. For the maintenance of the application switch, we still have to do that we need to regularly Scrub or remove some dirt because only in this way our switch will not have some problems with sensitivity. Although the product has IP67-level protection facilities, the product cannot be immersed in water for too long. Therefore, when the product is used outdoors, be sure to check the product after encountering heavy rain.



There are 6 main products used in the industrial segmented door, namely microwave radar sensor, 3D person-car separator, economical light curtain, photoelectric sensor, reflector photoelectric sensor, and loop coil detector.
G-TEK's single-beam photoelectric sensors and light curtains are the first choices for protecting and monitoring all types of automatic industrial doors, high-speed doors, sectional doors, garage doors, gate, and loading/docking applications. G-TEK's durable, high-performance and sophisticated sensor systems are designed to perform continuously in the most demanding door applications and environments, making them suitable for exteriors that are directly or indirectly exposed to harsh outdoor environments including sunlight, rain, dust, snow installation, and fluctuating temperatures. Additionally, the wear-resistant design of the G-TEK sensor makes it the first choice for the most challenging door installations, including refrigerated doors.
Specific product model:
1. Microwave radar sensor - GMR series
2. 3D man-car separator - GDC1102
3. Economical light curtain - LSE series
4. Photoelectric sensor - PMF 50T
5. Reflector photoelectric sensor - PMF50R
6. Toroidal coil detector - GVD series
The difference between the normal version and the laser version of PF50R
1. Aspherical optical lens to eliminate light interference
2. Easy to install, it can be fixed on the wall by using the bracket
3. One-piece design, can be used indoors and outdoors
1. Narrow beam design, more sensitive to sense objects
