Lifting doors

Sensor solutions for lifting doors

Industrial lift doors are also known as industrial sectional doors. It is the most common type of industrial door. It is based on the principle of installing the track as close as possible to the inside of the building, thus allowing a large saving of the interior space of the building. His operation is fast, the door is strong and wind resistant. This product is mainly used in outdoor environments. Application scenarios in addition to the passage of pedestrians and regular vehicles also need to consider whether objects that are irregular and difficult to be detected by the photoelectric sensors will be transported, such as logs, and steel bars. However, if a safety accident occurs, the consequences will be very serious, so the safety performance of the industrial sectional door is very important to protect. 


(1) Retro-reflective photocell sensors, mostly used on lifiting doors
Solutions:
The PF50R-AR laser retro-reflective photoelectric switches detects highly reflective objects easily and stress-free. Easy to install and easy to align with the red laser light source.
PF50R-AR laser photoelectric sensors has a one-piece molding housing design and an IP67 level of safety protection. This allows the product to cope with all kinds of outdoor weather. For the safety protection of sectional doors, it is necessary to solve the problem of highly reflective object detection. PF50R-AR laser retro-reflective photoelectric sensor built-in polarization sheet design can effectively filter stray light. Accurate detection of highly reflective objects transported by sectional doors, providing the safest use environment for application scenarios.

(2) Door blanking and more reliable detection
Solutions:
The LSE door-blanking type area protection light curtain with door-elimination function is more suitable for integration in industrial sectional doors.
Slim housing design allows the product to be perfectly concealed in the door chute on both sides. 
Hidden problem makes the door curtain in the process of falling even if the blocking beam point will not trigger the stop signal. The slim housing design and the door defeat function make the LSE area detection light curtain more suitable for integration into the door design.

In addition to the above two products, there are PM18T cylindrical photoelectric sensors and PF50T opposite photoelectric sensors are also suitable for industrial sectional door safety protection products. It is installed in the middle of the door as a guard. This product is usually used in combination with the PF50R. However, for large industrial sectional doors, PF50T is more suitable for the detection distance and higher detection accuracy of the PF50T through-beam sensors.
