Inductive proximity sensor 4mm | 90-250VAC | NO | IP65 | M12
Code: ES-Lj12A3-4-J/EZInductive proximity/position sensor designed to detect the presence of metals and distance, particularly suitable for industrial applications where high accuracy and reliability are required. The sensor operates with AC current (90–250VAC), has a simple two-wire connection, and an NO (normally open) contact. This sensor is durable and resistant to environmental factors, with an IP65 protection rating, meaning it is dustproof and resistant to water splashes. The sensor housing is made of brass with a nickel coating, and the sensor surface is made of ABS plastic.

This inductive proximity sensor is widely used in industries where accurate metal detection is required. Due to its compactness and easy installation, it is an ideal choice for automation systems, production lines, safety systems, and other areas where metal objects, such as bolts, steel parts, and other industrial components, need to be detected. The sensor is suitable for use in both dry and damp environments, as it has an IP65 protection rating.
Advantages:
Accurate detection: Can detect metallic objects up to a 4 mm distance, ideal for industrial applications.
Reverse connection protection: Provides additional protection and reliability in the system.
Waterproof and dustproof (IP65): Suitable for use in wet and dusty environments, ensuring long-term operation.
Disadvantages:No short-circuit protection: Therefore, the risk of sensor failure increases in short-circuit situations.
Only detects magnetic metals: If the object's material is not magnetic metal, the detection distance will be significantly reduced.
Mounting compatibility: Mounting is only possible using specific M12 brackets and 3-wire connections, so additional accessories or configurations may be needed.Illustrative image may have been created using AI.
