‌English Version‌
The SN04-N3 rectangular inductive proximity sensor is a non-contact detection device designed for industrial automation applications. Its compact rectangular housing optimizes installation space, making it suitable for equipment with complex mechanical structures or limited space. Utilizing electromagnetic induction principles, the sensor achieves precise detection of metallic objects with an effective sensing distance of 4mm. It reliably detects targets made of iron, steel, copper, and other metals, with a response frequency of 1kHz to meet dynamic detection requirements.

Constructed with a durable engineering plastic housing and internal epoxy resin encapsulation, the sensor operates reliably in temperatures ranging from -25℃ to +70℃ and environments with humidity ≤95%, adapting to workshops, warehouses, and production lines. The core circuit incorporates overload protection and anti-interference design, minimizing false triggers and enhancing system stability. The DC three-wire output (NPN/PNP optional) is compatible with mainstream PLCs and controllers, while the anti-loosening terminal design reduces maintenance needs.

The SN04-N3 offers flexible installation with standard threaded holes on both sides, allowing horizontal or vertical mounting. An integrated status indicator simplifies on-site debugging. Ideal for machine tool positioning, conveyor belt counting, and safety access control, the sensor improves detection efficiency and system safety. The corrosion-resistant housing with IP67 protection ensures long-term performance in dusty or oily environments.
