■ Product Description

Proximity switch is a displacement sensor with switching output, including NPN, PNP, normally open, normally closed, and relay options. It detects transparent and opaque objects such as metal (iron, steel, copper), plastic, glass, wood, water, paper, and magnets. It integrates seamlessly with PLC, servo controllers, frequency converters, counters, and controllers for automated signal input across machinery, textile, light industry, papermaking, printing, and packaging industries.

Inductive proximity switch: Detects metal objects (iron, steel, copper, etc.).
Capacitive proximity switch: Detects any object (glass, metal, plastic, water, oil, paper, etc.).
Hall proximity switch: Detects magnetic metal (magnets).
This series implements the GB/T14048.10 standard.

Frequently Asked Questions

Q1: What materials can the LJAS series inductive proximity switch detect? A1: The inductive proximity switch is specifically designed to detect metal objects such as iron, steel, and copper.

Q2: What is the protection rating for these sensors? A2: These sensors feature an IP67 protection level, making them resistant to dust and water immersion.

Q3: How do the dual light indicators help during operation? A3: The green indicator shows that the power is on, while the red indicator lights up when the sensor detects an object and performs an action.

Q4: Can these sensors be used with a PLC? A4: Yes, they are widely used with PLCs, servo controllers, frequency converters, and counters for automated signal processing.

Q5: What is the standard detection distance for the LJA18S model? A5: The standard detection distance is 5mm with a ±10% tolerance range.

Q6: What is the operating temperature range? A6: The operating temperature range is -25 to +70°C, provided there is no icing or condensation.
