Elevator is one of the essential facilities in modern buildings, and its safety is directly related to the life and property safety of passengers and objects. In order to ensure the safety of the elevator, the elevator is equipped with various safety devices. U-type sensor belongs to one kind of photoelectric sensor, its transmitter and receiver are located at the left and right ends. A one-piece design makes installation more convenient. It is mainly used in the leveling control system of the elevator.

PMK product features:

1. Compact size, easy to install: due to its compact size, it can be more easily installed in narrow spaces.

2. Normally open, normally closed in one: knob mediation, can be used both normally open and normally closed. Adapt to different working requirements.

3. 360-degree visual LED indicator: LED indicator can display the induction status in all directions, providing more intuitive working status information.

4. Fast response speed, frequency up to MAX.1ms: fast sensing and feedback on the detected objects.

5. Smaller sensing trigger point, longer sensing distance, providing more accurate and sensitive triggering effect.

6.Waterproof up to IP67: High-grade protective housing, adapts to a variety of application environments, also suitable for applications in wet environments.

Industry applications for slot photoelectric sensors:

Automated Production Lines 
In automated production lines, slot-type photoelectric sensors can be used to detect the position of objects, for example, to detect whether parts or products are correctly placed in the designated position, to ensure the accuracy and smooth running of the production process. At the same time, a slot photoelectric sensor can also be used to monitor the operating status of the conveyor belt, such as whether the conveyor belt is running normally, whether there is a blockage and other problems, so as to realize the automation control and monitoring of the production line.

Packaging
In the packaging industry, slot photoelectric sensors can be used to detect the position and quantity of packaging materials. For example, installing a slot-type photoelectric sensor on automatic packaging machines can monitor the position of packaging materials in real-time, ensuring the accuracy and efficiency of the packaging process. In addition, slot-type photoelectric sensors can also be used for counting packages, by sensing the packages in place and out of place, to realize the monitoring and control of the number of packages.

Logistics Industry
In the logistics industry, slot-type photoelectric sensors can be used for counting, sorting, and positioning items. For example, in logistics sorting centers, slot-type photoelectric sensors can be used to sense items in place and out of place to achieve accurate counting and sorting of items. At the same time, slot-type photoelectric sensors can also be used for the positioning of goods, through the sensing of the position of the goods to ensure the accuracy and efficiency of logistics operations.

Electronic equipment industry
In the electronic equipment industry, slot-type photoelectric sensors can be used to detect the position and status of internal components and the triggering of electronic switches. For example, in the assembly process of electronic equipment, the slot-type photoelectric sensor can be used to sense the position of components to ensure the correct installation and contact of the components; at the same time, the slot-type photoelectric sensor can also be used to sense the triggering of electronic switches to realize the monitoring and control of the switch state.
