The Bedook Proximity Switch with TEACH-in 5/10mm is a highly sophisticated and versatile electrical component that plays a crucial role in a wide range of industrial and technological applications. This proximity switch, with its unique cuboid shape, stands out among its counterparts due to its advanced features and capabilities.
It offers several model options, including NPN NO/NPN NC/PNP NO/PNP NC. These diverse models provide flexibility for different circuit configurations and user requirements. For example, the NPN NO model is ideal for applications where a normally open circuit is needed, while the NPN NC model is suitable for normally – closed circuit requirements.
The Bedook Proximity Switch with TEACH-in 5/10mm features a high switching frequency of 100Hz. This high frequency is of great significance in industrial automation applications. In high-speed production lines, such as those in the food packaging industry where thousands of packages may pass through the production line per minute, the proximity switch needs to quickly and accurately detect the presence or absence of products. The 100Hz switching frequency ensures that the switch can respond rapidly to the changing positions of the products, enabling seamless and error-free production processes.
Operating Voltage
The operating voltage range of 10 – 30VDC(±10%) is a remarkable feature. In industrial environments, power supply voltages can often vary due to factors such as load fluctuations and electrical interference. This wide voltage range allows the proximity switch to operate stably under different voltage conditions.
- No-Load Current: The no-load current is ≤15mA. This low no-load current is beneficial in applications where the switch is in standby mode for extended periods.
- Load Current: The load current is ≤150mA. This relatively low load current ensures that the switch does not consume excessive power during operation, contributing to overall energy efficiency.
- Repeatability Precision: With a repeatability precision of ≤(±5.0%), the switch provides highly accurate and consistent detection results. In precision manufacturing industries, such as semiconductor manufacturing, where the accurate positioning of components is critical, the high repeatability precision of the proximity switch ensures that the detection of components’ positions is reliable, minimizing production errors.
- Protection Mechanisms: It includes comprehensive protection features such as short – circuit protection, polarity protection, and overload protection. In industrial control systems, electrical faults such as short – circuits and overloads can occur due to various reasons, such as equipment malfunctions or power surges. The presence of these protection mechanisms safeguards the proximity switch from damage, ensuring the stability and longevity of the entire system.
The TEACH-in function is a standout feature of this proximity switch.
- Principle and Operation: This function allows the switch to “learn” the characteristics of the objects it needs to detect. When activated, the switch measures and analyzes the electrical properties, such as capacitance changes, associated with the presence of the target objects. For example, in a material handling system with various types of materials, the switch can be taught to distinguish between different materials based on their unique electrical signatures.
- Advantages in Adaptability: It enables the switch to adapt to different environments and detection objects without the need for complex manual adjustments. In a changing production environment where new materials or product designs are introduced, the TEACH-in function allows the proximity switch to quickly reconfigure itself to detect new objects accurately.
- Temperature Range: The switch can operate in an ambient temperature range of – 25 – 70°C. This wide temperature range makes it suitable for both extreme cold and hot environments. In outdoor applications, such as in solar panel tracking systems where the equipment is exposed to harsh weather conditions ranging from freezing winters to scorching summers, the proximity switch can maintain its functionality.
- Protection Level: With an IP67 protection level, it is highly resistant to dust and water ingress. In dusty industrial environments, such as cement factories, or in wet environments like water treatment plants, the switch can operate reliably without being affected by dust or water, ensuring consistent performance.
The action indicator lights include green (normally open), yellow (normally closed), and output lights. These lights provide clear visual feedback on the switch’s operating status. In a complex industrial control panel, operators can quickly assess the status of the proximity switch by observing the indicator lights, facilitating troubleshooting and system monitoring.

- Production Line Material Detection: In automotive manufacturing, for example, the proximity switch can be used to detect the presence and position of engine components on the production line. The switch’s detection capabilities can ensure that each component is in the correct position for the next manufacturing step. The high switching frequency and precision of the switch guarantee accurate and timely detection, preventing production errors.
- Assembly Part Positioning: In the assembly of electronic devices, such as smartphones, the proximity switch can assist in positioning tiny components like microchips and resistors. The TEACH-in function allows the switch to adapt to the different shapes and materials of these components, ensuring precise assembly. The low-power consumption feature is also beneficial in this context, as it helps to reduce the overall power consumption of the assembly equipment.
- Automated Packaging Systems: In the pharmaceutical industry, the switch can be used to detect the presence of medicine bottles and ensure proper packaging. It can accurately identify the position of the bottles, whether they are made of plastic or glass, and trigger the packaging mechanism at the right time. The wide operating voltage range ensures stable operation of the switch even with potential voltage fluctuations in the packaging equipment.
- Cargo Sorting: In large – scale logistics centers, the proximity switch can be applied to sort packages based on their contents. For example, it can distinguish between packages containing metal products, plastic toys, or paper – based goods. The TEACH – in function allows the switch to quickly learn and adapt to the different electrical characteristics of various packages, improving the efficiency and accuracy of the sorting process.
- Inventory Monitoring: In chemical warehouses, the switch can monitor the liquid levels in storage tanks. By detecting the capacitance changes associated with the liquid – tank interface, it can prevent overflows and ensure proper inventory management.
