IFM Laser sensors

Modern security systems for residential, coastal and industrial facilities. Their task is to instantly detect extraneous activity and implement the mechanism of occurrence - turning on the alarm, calling the guard, etc.

An important component of security systems has become laser sensors - high-precision devices that can detect movements and determine the size of an object with high accuracy. They are small in size and consume minimal energy, while there is protection against intrusions from the outside.

IFM Efector laser sensors is a perfect solution for precise measurements and long distance monitoring and motion control.

There are several types of laser sensors: though-beam, retro-reflective and with diffuse reflection. Its light beam consists of multiply light waves with the same length. Due to such technology, devices have small divergence angle, so they can operate to large distances.

What are laser sensors?

Laser sensors determine the position of objects on the conveyor belt, evaluate the fullness of various containers and perform many other functions. Determining the dimensions of objects for various purposes. The laser allows you to estimate the length, width, height, thickness of an object at a distance with an accuracy of a millimeter.

How does a laser sensor work?

The principle of operation of IFM laser sensor is based on the triangulation method for measuring the distance to an object. The laser beam, which differs from ordinary light in the high parallelism of the beam, emitted from the receiver, falls on the surface.

The basis of the laser sensor is the triangulation principle - measuring the distance to any object using a triangle. The receiver emits a laser beam with a high beam parallelism - it hits the surface and is reflected from it at a certain angle depending on the distance to the object. The surface of the vast majority of objects is rough - it has many tubercles, so the beam is reflected from these irregularities and enters the receiver.

Types and characteristics of laser sensors

The most common variety is phase-type sensors. They are able to estimate not only the distance to the object, but also its shape and size. This makes them especially handy when installing burglar alarms.

When choosing such equipment, it is necessary to pay attention to the following operating parameters:

Measuring range.
Accuracy of measurements.
The output signal format that the microcontroller sends for further response.
Operating temperature range
Dimensions. The security system should be effective, but as inconspicuous as possible.

Where are laser sensors used?

Laser movement and distance sensors are in great demand in automated security systems. Beams can pass in corridors, on the territory, in walk-through areas, doorways and not only. As soon as the system detects the intersection of the laser beam, the microcontroller will determine the size of the object and the distance to it, if a threat is detected, it will send a signal to the security console and start the alarm. The high accuracy of measurements allows to reduce the number of guards - the perimeter will be constantly under control, and even a small object cannot go unnoticed.

However, laser sensors are in demand not only in the security sector. The ability to accurately measure the distance in a non-contact way is used in many industrial and other industries:

Woodworking and metalworking
Construction
Various industries

Determining the dimensions of objects for various purposes. The laser allows you to estimate the length, width, height, thickness of an object at a distance with an accuracy of a millimeter.

Laser sensors have become widespread due to several important advantages:

Long operating range
Ease of adjustment.
Light protection.
Interference protection.

Beam sensors are able to accurately determine the distance to the object, instantly respond to intrusion into the protected area, while they work completely silently and consume a small amount of energy. Any object will receive effective permanent protection, and even a small object entering the protected area will be recorded. Such sensors are reliable and durable due to their simple design.

IFM Electronic produces different series of laser sensors:

Completer product line
