Stainless steel explosion-proof limit switch

The operation principle of the 3S series explosion-proof limit switch is similar to other limit switches, which are based on the collision of mechanical moving parts to trigger the switch action. When the moving part reaches the preset position, it will collide with the operating head of the limit switch, so as to make the contact system operate and realize the circuit is connected or broken. This kind of switch is usually used in the small current control circuit to realize the functions of sequence control, positioning control and position state detection.

• High sensitivity and accuracy: The 3S series limit switch has high precision and high sensitivity, and can accurately detect small movements of mechanical equipment to ensure accurate transmission of control signals.

• Variety and flexibility: The range of limit switches is available in a variety of models and specifications, including different contact types, modes of operation, protection levels, etc., to meet the needs of different application scenarios.

• High reliability: The 3S series limit switches are made of high-quality materials and advanced manufacturing processes, with high reliability and durability, and can operate stably in harsh environments for a long time.

• Easy installation and maintenance: This series of limit switches is compact and easy to install, while offering an easy maintenance design for daily inspection and replacement.
