How to choose photoelectric sensors

2022年01月17日

There are many different types of photoelectric sensors, but in reality, there are only four basic technologies: counter reflection, reflector plate, diffuse reflection, and background suppression.
1、 Opposing photoelectric sensor
Advantages:
Suitable for accuracy among the four types of photoelectric sensors
The sensing range of the four types of photoelectric sensors is suitable for long
Very high reliability
Disadvantages:
Must be installed at two locations in the application system: transmitter and receiver
High cost: must purchase both transmitter and receiver simultaneously
2、 Reflective plate photoelectric sensor
Advantages:
Cost lower than opposed photoelectric sensors
The accuracy is only lower than that of direct injection
Sensing range greater than diffuse reflection
High reliability
Disadvantages:
Must be installed at two locations in the application system: transmitter and reflector board
The cost is slightly higher than diffuse reflection
The induction range is smaller than the direct type
3、 Diffuse reflection photoelectric sensor
Advantages:
Only installed on one side of the application
Cost lower than opposed and reflective panels
Disadvantages:
It's not as accurate as the projection or reflection plate type
More setup time may be required
4、 Background suppression type photoelectric sensor
Advantages:
Can be effective in reflective backgrounds
Disadvantages:
The cost is higher than that of diffuse reflection, reflective plate or counter reflection
Suitable for long debugging setup time

Lide Electronics takes you to learn about proximity switches

A proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch to the operating distance, it can be activated without mechanical contact or any pressure applied, thereby driving DC appliances or providing control commands to computer (PLC) devices. Proximity switch is a type of switch type sensor (i.e. contactless switch) that combines the characteristics of travel switch and micro switch, as well as sensing performance. It has reliable operation, stable performance, fast frequency response, long application life, strong anti-interference ability, and is also waterproof, shockproof, and corrosion-resistant. The products include inductive, capacitive, Hall, AC, and DC types.

Precautions for using proximity switches

Proximity switches (proximity sensors) are widely used in aviation, aerospace technology, and industrial production. In daily life, such as hotels, restaurants, and garages, automatic doors and automatic hot air fans are all used. In terms of security and theft prevention, important places such as data archives, finance and accounting, museums, and vaults are usually equipped with anti-theft devices composed of various proximity switches. In measurement techniques, such as length and position measurement; In control technology, such as displacement, velocity, and acceleration measurement and control, a large number of proximity switches are also used.
