Heschen M18 Proximity Sensor Switch LJC18A3-B/EZ 10mm 90-250VAC

Description

Product Overview

The Heschen M18 Capacitive Proximity Sensor Switch, model LJC18A3-B/EZ, is engineered to provide precise, non‑contact detection of dielectric materials within a 10 mm range. Constructed with high‑quality polymer housing, the sensor tolerates harsh industrial environments while maintaining stable performance. It operates on a broad voltage spectrum of 90‑250 VAC, delivering a reliable 400 mA output in a normally‑open configuration. The non‑shielded design reduces electromagnetic interference, making it suitable for a variety of automation applications where accuracy and durability are paramount.

Usage

Designed for industrial automation, this sensor excels in material level monitoring, conveyor belt tracking, and safety interlock systems. Its compact 18 mm mounting hole allows easy installation on standard panels, while the 10 mm detection distance ensures early detection of objects without physical contact. Engineers and technicians can integrate the sensor into PLC‑controlled processes, using its 400 mA output to trigger relays, alarms, or motor controls. The wide voltage range accommodates diverse power supplies, reducing the need for additional converters.

In harsh environments such as manufacturing floors, food processing plants, and chemical handling facilities, the sensor’s robust construction resists dust, moisture, and temperature fluctuations. Its non‑shielded terminals simplify wiring, and the normally‑open contact type provides a clear signal when the target material enters the detection zone, enhancing safety and operational efficiency.

FAQ

What types of materials can the sensor detect?

The sensor is capacitive, meaning it can detect any non‑metallic (dielectric) material such as plastics, liquids, powders, and wood within its 10 mm range.

Is the sensor compatible with standard PLC systems?

Yes, the 400 mA normally‑open output is designed to interface directly with most PLC input modules, relays, and alarm circuits without additional signal conditioning.

Can the sensor operate in high‑temperature environments?

The sensor is rated for typical industrial temperature ranges and can function reliably in environments up to 70 °C, making it suitable for many manufacturing applications.

What is the recommended mounting method?

Mount the sensor using the 18 mm mounting hole on a flat panel or enclosure. Ensure the sensor face is unobstructed for optimal detection performance.

How do I troubleshoot a sensor that is not responding?

First, verify the power supply is within the 90‑250 VAC range and that wiring follows the provided diagram. Check for any physical obstructions on the sensor face and confirm the target material is within the specified detection distance. If the issue persists, contact Heschen technical support for further assistance.
