ZSE20A-R-01: Precise Sensing, Contactless Detection! Magnetic Proximity Switch Enables Cylinder Position Detection

In automation systems, the real-time and accurate detection of the cylinder piston rod’s position is crucial for achieving precise control, motion feedback, and safety interlocking. The ZSE20A-R-01 Magnetic Switch (also known as a Magnetic Proximity Switch) is specifically designed for detecting cylinder piston position. It outputs highly reliable electrical signals through contactless sensing of the magnetic ring on the cylinder piston, serving as a fundamental component for enabling intelligent cylinder control.Core Product Advantages

• Contactless Sensing, High Reliability​Utilizes Hall effect or magnetoresistive principles for contactless interaction with the magnetic ring on the cylinder piston. Features no mechanical wear, long service life, strong resistance to contamination, and extremely high reliability.
• High Switching Frequency & Fast Response​Offers fast response time (<1ms) and high switching frequency, meeting the position detection requirements for cylinders performing high-speed, high-frequency operations.
• Multiple Output Signals​Provides NPN (Normally Open/Normally Closed) or PNP transistor outputs, allowing direct connection to PLCs, relays, or controllers with strong compatibility.
• IP67 High Protection Rating​Excellent housing sealing achieves an IP67 protection rating, providing dust and water resistance, and adaptability to harsh industrial environments such as those with moisture and oil contamination.
• Dual-Color LED Status Indication​Built-in dual-color (Red/Green) LED indicators clearly display power status (green) and switching action status (red), facilitating on-site debugging and fault diagnosis.
