SQB1 switch, German SIBA model SQB1 price

SQB1 switches are used in robots to emulate tactile functions. Tactile sense is an important sensory function when humans directly contact the external environment. Developing tactile switches that meet requirements is one of the technical keys in robot development. With the development of microelectronics and the emergence of various organic materials, a variety of development schemes for tactile switches have been proposed, but most are currently at the laboratory stage, with few reaching commercialization. Tactile switches can be roughly classified by function into contact switches, force-torque switches, pressure switches, and slip switches. Valve SQB1 switch classification

The basic principle of multi-switch information fusion technology is similar to the human brain's process of comprehensively processing information. It performs multi-level, multi-spatial information complementarity and optimized combination processing on various switches, ultimately producing a consistent interpretation of the observed environment. In this process, multi-source data must be fully utilized for reasonable allocation and use. The ultimate goal of information fusion is to derive more useful information by combining information from multiple levels and aspects based on separate observation data obtained from each switch. This not only leverages the advantage of collaborative operation among multiple switches but also comprehensively processes data from other information sources to enhance the intelligence of the entire switch system. Pressure switches are the most widely used type of switch. Traditional pressure switches are primarily mechanical devices that indicate pressure through the deformation of elastic elements, but such structures are large in size, heavy in weight, and cannot provide electrical output. With the development of semiconductor technology, semiconductor pressure switches have emerged. Their characteristics include small size, light weight, high accuracy, and good temperature characteristics. Especially with the development of MEMS technology, semiconductor switches are moving towards miniaturization, featuring low power consumption and high reliability.

SQB1 switch installation precautions

1) Correct installation method: Using appropriate instruments, verify the frequency response value of the pressure switch under normal atmospheric pressure and standard temperature conditions. Verify the correctness of the pressure switch code and the corresponding frequency response signal. 2) Determine specific installation location: To determine the numbering and specific installation location of pressure switches, consider each inflation section of the inflation network. Pressure switches must be installed along the cable, preferably at cable joints. Install no fewer than 4 pressure switches on each cable. The two pressure switches closest to the telephone exchange shall not be more than 200m apart. Install 1 at each end of every cable. Install 1 at each branch point of the cable; if two branch points are close together (less than 100 m), only 1 needs to be installed. Install 1 where the cable laying method (overhead, underground) changes. For cables without branches, since the cable specifications are consistent, the installation spacing of pressure switches shall not exceed 500m, and the total number shall be no less than 4. To facilitate the identification of pressure switch fault points, in addition to installing a pressure switch at the starting point, install another 1 at a distance of 150~200m from the starting point. Of course, economic and technical factors must be considered in the design; pressure switches should not be installed where they are not needed.

SQB1 switch applications

Pressure switches are mainly applied in: booster cylinders, boosters, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air conditioning and refrigeration equipment, and other fields. 1) Application in hydraulic systems: In hydraulic systems, pressure switches are primarily used to complete closed-loop force control. When the control valve spool moves suddenly, a peak pressure several times the system operating pressure forms within a very short time. In typical mobile machinery and industrial hydraulics, if such extreme conditions are not considered during design, any pressure switch will be damaged quickly. Shock-resistant pressure switches are required. There are 2 main methods for achieving shock resistance in pressure switches: one is to replace the strain gauge chip, and the other is to use an external coil. The first method is generally adopted in hydraulic systems, mainly due to ease of installation. Another reason is that the pressure switch must withstand continuous pressure pulsations from the hydraulic pump. 2) Application in safety control systems: Pressure switches are frequently used in safety control systems, primarily targeting the safety management system of air compressors themselves. There are many switch applications in the field of safety control. As a very common type of switch, it is not surprising that pressure switches are used in safety control systems. Applications in the safety control field are generally considered from the perspectives of performance, price, and operational safety and convenience. Practical evidence shows that selecting pressure switches yields very good results. Pressure switches use machining technology for mechanical equipment to mount components and signal regulators onto a small chip. Therefore, small size is one of its advantages. In addition, low price is another major advantage. To some extent, it can improve the accuracy of system testing. In safety control systems, installing pressure switches in the pipeline equipment at the air outlet controls the pressure generated by the compressor to a certain extent, serving as a protective measure and a highly effective control system. After the compressor starts normally, if the pressure value does not reach the upper limit, the controller opens the intake port to adjust the equipment to achieve maximum power. 3) Application in injection molds: Pressure switches play an important role in injection molds. Pressure switches can be installed in the nozzle of the injection molding machine, hot runner systems, cold runner systems, and mold cavities. They can measure the plastic pressure at a certain point between the nozzle of the injection molding machine and the mold cavity during the processes of injection, filling, holding pressure, and cooling. 4) Application in monitoring mine pressure: Switch technology is one of the key technologies for mine pressure monitoring. On one hand, we should correctly apply existing various switches to serve the mining industry; on the other hand, as switch manufacturers, we must research and develop new types of pressure switches to adapt to more mining industry applications. There are various types of pressure switches. Due to the special environment of mine pressure monitoring, mine-used pressure switches mainly include: vibrating wire pressure switches, semiconductor piezoresistive pressure switches, metal strain gauge pressure switches, and differential transformer pressure switches. These switches are widely used in the mining industry. The specific type of switch to use depends on the specific mining environment. 5) Application in compressors and air conditioning/refrigeration equipment: Pressure switches are commonly used in air compressors and air conditioning/refrigeration equipment. These switch products are compact in shape, easy to install, and typically use specialized valve needle designs for pressure ports.
