The elbow touch switch is very durable, especially it can be operated with the elbow. Avoid hand contact. There are also foot switches, which have the same function, but have higher requirements for waterproofing, and the power of the foot is very large, which easily makes the foot switch invalid. There is also a handle with a contact switch that provides a contact signal to the door machine when the handle is pushed (or pulled in the opposite direction) into place. Building automation sometimes makes special requirements, such as using a telephone branch to control door opening. To meet this requirement, it is only necessary to ensure that the signal is a passive contact signal. In some cases, people will ask for antenna remote control. A wireless receiver is used to make a contact connection with the Automatic door, and then a wireless transmitter is used to meet the requirements.It can be divided into arc segments, semicircles and full circles, with or without fixed door pages. The arc can be set according to the specific case design.https://www.kth-automaticdoor.com/
The application is very flexible. It can also be stitched with different arcs to make it beautiful and changeable. The geometric shape of the door body, therefore, the use of Caesar's curved door will become more and more widespread. According to the material of the door body: there are safety glass, stainless steel finish, building aluminum alloy profile, color coated steel plate, wood, etc. Other materials can also be used. The common types of it are frameless glass automatic door, stainless steel frame glass automatic door and aluminum alloy frame (planed or fluorocarbon spray paint) glass automatic door. According to the structural characteristics of the door, automatic doors are mainly divided into nine categories, namely automatic revolving doors, arc-shaped automatic doors, smooth automatic doors, flat automatic doors, folding automatic doors, telescopic automatic doors, rolling automatic doors, lifting Type automatic door and automatic blocker. The driving device of the automatic door is composed of a motor and a reducer or a motor and a hydraulic system. The driving device operates according to a program set by the control device to drive the door to open and close. There is a transmission mechanism in the middle from the driving device to the movement of the door, and the reducer is a part of the transmission mechanism. Most of the reducer and the motor have been integrated into a reducer motor, which will simplify the equipment and make it easy to standardize and miniaturize. In addition to the reducer, the transmission mechanism must be designed according to specific needs. The transmission mechanism can be gear transmission, chain transmission, or high-efficiency synchronous belt transmission.
