Product Description

The LJ18A3-5-Z/AY sensor is an inductive proximity switch designed for precise non-contact detection in industrial applications. This 5mm proximity sensor features a detection range of up to 5mm, operating within a DC voltage range of 10-30V, and supports a temperature tolerance of -25°C to +70°C. It provides a single digital output (PNP/NPN configurable) for direct integration with PLCs, relays, or control modules. With IP67 protection, it is widely used in automation, machinery, and assembly lines for metal object detection. The sensor's compact cylindrical design ensures easy installation, while its high switching frequency and anti-interference capabilities enhance reliability. A limitation is its exclusive suitability for metallic targets. No internal battery or display is required, as it functions purely through electromagnetic sensing.
