IFM switch German IFM model IFM price

IFM switch is a device with the ability to sense the approach of objects. It utilizes the sensitivity of displacement switches to approaching objects to identify proximity and output corresponding switch signals; therefore, proximity switches are commonly referred to as proximity switches. It is a general term for switches that replace contact-based detection methods such as limit switches, with the aim of non-contact detection of the target object. It can detect the movement and presence information of the object and convert it into electrical signals.

IFM switch applications

The most widespread application of proximity switches is in mobile phones. Smartphones on the market all contain proximity switches. When a user makes a call, the phone is close to the ear, which can easily lead to accidental operations (for example, cheeks puffing out when laughing may hang up the call). Therefore, a proximity switch is needed to monitor the distance in real time and automatically turn off the screen when the distance is too close, thereby preventing accidental operations. In addition, proximity switches are also widely used for measuring mine shaft depth, detecting aircraft altitude, and exploring outdoor environments. With the continuous development of technology, they also show prominent performance in wearable devices (such as smart belts).

IFM switch working principle

When the time-of-flight laser switch is in operation. The time-of-flight laser switch must measure the transmission time extremely accurately because the speed of light is too fast. For example, the speed of light is approximately 3´108m/s. To achieve a resolution of 1mm, the electronic circuit of the time-of-flight ranging switch must be able to resolve the following extremely short time: 0.001m¸(3´108m/s)=3ps. Resolving a time of 3ps places excessive demands on electronic technology and is too costly to implement. However, today's inexpensive time-of-flight laser switches cleverly avoid this obstacle by utilizing a simple statistical principle, namely the law of averages, to achieve a resolution of 1mm while ensuring response speed.

IFM switch industry applications

1) Application in taxi meter testing systems: To further promote energy conservation and emission reduction and address the metrology needs of the electric vehicle industry, the mobile electric taxi meter testing system has been officially launched. The testing device is roughly divided into two parts: one is a main unit about the size of a briefcase, placed on the rear seat of the car, and the other is a distance-measuring switch attached to the car body. According to reports, the device uses the driving distance measurement method. As the driver drives the car for a certain distance, the testing device and the meter sample synchronously. The entire testing process is expected to be completed in about seven to eight minutes. 2) Wide range of applications in the field of automation: Nowadays, in addition to ultrasonic switches and standard photoelectric switches, automatic detection and control methods have added a new solution for long-distance measurement and inspection—the time-of-flight laser distance switch. It provides application flexibility for various scenarios, including the following: (1) Equipment positioning. (2) Measuring the material level of material packages. (3) Measuring the distance and height of objects on conveyor belts. (4) Measuring log diameter. (5) Protecting overhead cranes from collisions. (6) Error-free inspection scenarios. (7) Monitoring aircraft ground clearance.
