AL-01D/DF Magnetic Proximity Switch Introduction
The AL-01D/DF series is a two-wire non-contact magnetic proximity switch developed based on magneto-inductive principles, designed for position detection in industrial automation systems. This device utilizes magnetic field interaction between built-in sensors and external actuators to achieve reliable signal triggering, effectively eliminating mechanical wear caused by physical contact and improving operational reliability.
Featuring a compact housing constructed with high-strength engineering plastics and metal composites, the switch demonstrates both lightweight characteristics and impact resistance. The optimized circuit design ensures low power consumption with operating current ranging 10-30mA, compatible with various industrial control systems. The core sensing module detects metallic targets through magnetic field variation, offering effective detection distance of 10-15mm (installation dependent) and response time under 2ms, suitable for high-speed production line applications. With IP67 protection rating, it withstands dusty environments and temporary liquid exposure.
This model provides selectable normally open (NO) or normally closed (NC) output modes, supporting 10-30V DC wide voltage input. The two-wire configuration simplifies field wiring complexity. Operating temperature range spans -25℃ to +70℃, ensuring stable performance in workshop environments. Both flush-mounted and non-flush installation options allow flexible adaptation to equipment structures.
Typical applications include safety door status monitoring for CNC machines, workpiece positioning verification on automated assembly lines, and location control in logistics sorting systems. The contactless working principle makes it particularly suitable for high-frequency detection scenarios or industrial environments with oil contamination and vibration, providing enhanced signal transmission compared to traditional mechanical limit switches.
