In recent years, elevated three-dimensional garages have gained more and more attention and use due to their high efficiency and land saving. Stereo garages can be placed in different types of garages according to different sites. Nowadays, many cities take three-dimensional garages as an indispensable part of their transportation and parking systems.
There is a growing demand for photoelectric sensors in the industrial sector as they can be used to detect positional deviations. The position of the product is measured by placing the sensor at a predetermined location, which helps to know whether the product has been placed correctly or not. In stereo parking photoelectric sensors are again used to detect the presence or absence of vehicles in a parking space. When the space is full, the sensor transmits the detection information to the parking center system and informs the outside about the status of the space through a digital display. It is convenient for parking owners to check and reduce the waste of time. Sensor shape is small and easy to install, detecting the presence or absence of vehicles is also to help the carrier plate to park the vehicle when choosing an empty parking space.

Stereo garages are equipped with a special loading plate for each parking space and the entire process of entering the vehicle is accomplished by an electrically controlled lift and traverse drive system. All the driver needs to do in this process is to drive the car into the designated loading plate in front of him. The plate will be parked in front of the designated storage space under the control of the drive system, and then the mechanical equipment at the bottom will lift the vehicle and transport it into the parking space. It is important to make sure that the carrier plate is parked in place. Proximity sensors primarily detect metal objects. They have stable performance, high tolerance of hazardous environments, low maintenance requirements, low cost and high efficiency. It is the device of choice for positioning detection. So let's take a look at how the proximity sensor is applied in the stereo parking.

1. Carrier plate lift in place detection: IM18, IF40 proximity sensors
The upper level of the carrier plate for lifting movement, the need for each carrier plate vertical movement of the track at the point of the stratification were installed a limit switch, used to detect the carrier plate down and up in place or not. Capacitive proximity switches IM18 and IF40 series proximity switches can be used here, which have a long detection distance and can leave enough safety distance for the moving machinery.

IM18 proximity sensor features:
1.Reverse polarity protection
2.Short-circuit protection Long-life & high reliability
3.Yellow Led indicates working status of sensor
4.Economical and easy to operate
5.Alternatives for mini switch and limit switch
6.Delay at power-up, guard against false pulse

IF40 proximity sensor features:
1.40mm×40mm square housing
2.Plug-in installation type, simple and convenient
3.Detecting temperature: -25~70°C
4.Protection grade IP67

2. Detecting the presence or absence of cars on the carrier plate: PF50T counter-emitting photoelectric sensors
A set of PF50T diagonal photoelectric switches is placed on the diagonal of each carrier plate, which is used to detect the presence or absence of vehicles on the carrier plate. When the counter-emitting photoelectric light path is blocked by the car, the sensor gives a signal to the system to carry out the next action.PF50T photoelectric sensor adopts infrared light source, the counter-emitting installation distance is up to 50 m. It can simultaneously meet the needs of the detection of the parking space of various specifications and sizes.
PF50T Photoelectric Sensor Features:
1.Through beam type, 10m/18m/25m/50m detecting distance
2.High reliability, can work normally in harsh environments
3.Stable and reliable in a robust housing
4.Integral package, protection rating IP67
