In the field of spraying, such as metal spraying, door panel spraying, window spraying, auto parts spraying, etc., these spraying themselves are toxic. If operators are exposed to them for a long time, their physical safety will be greatly affected.

The spraying detection light curtain can effectively detect the position of the workpiece, realize the efficient and automatic spraying of the spray gun, reduce the close contact between the human body and the spraying, and effectively solve the safety problem of spraying. It not only saves a lot of manpower and material resources, but also does not harm people's health.

What is the spraying light curtain? The spraying light curtain is an important part of a comprehensive automatic spraying control device. It is composed of a set of measuring light curtain, which is connected with the controller through a signal line. The transmitter and receiver are both located in front of the entrance of the spraying machine. The profiles to be sprayed are hung on the movable support. The signals are transmitted to the controller through the length of profiles and the light blocking area through the automatic nozzle after passing through the receiving and transmitting light screens at a uniform speed, The controller calculates the time delay according to the distance between the receiving base and the spraying machine and the speed of moving the support, and controls the spraying machine to change the vertical round-trip distance of the spray gun when the profile arrives, so as to avoid spraying paint to the corresponding light blocking position, save paint, reduce pollution, reduce costs, and thus increase the economic benefits of the company.

PTM spraying tracking, positioning and measuring light curtain parameter information:

Output digital quantity or analog quantity to facilitate the spray controller to receive signals;

High sensitivity and fast detection speed. It can be used for high-speed spraying machine;

The detection accuracy is high, and the painting is usually 20 or 40mm.

There are many models to facilitate the matching of various equipment and use occasions;

High reliability, anti light and electromagnetic interference;

The product adopts anti loose gold-plated aviation plug with firm connection;

Anti reverse connection protection and output short circuit protection;

Wide working voltage range DC10V~DC30V can work reliably;

Good anti-seismic and dust-proof performance (both the end cover and the filter are provided with gaskets).
