Capacitive Proximity Sensor Heschen LJC30A3-10-Z/CY 4‑Wire 10‑30VDC

Description

Product Overview

The Heschen LJC30A3-10-Z/CY is a high‑performance capacitive proximity sensor designed for demanding industrial environments. Built with a copper‑based sensing element, the device detects any dielectric material within a configurable range of 1‑10 mm, with a typical detection distance of 10 mm ±10 %. Its shielded construction protects against electromagnetic interference, ensuring reliable operation in noisy PLC and automation settings. The sensor operates on a wide voltage range of 10‑30 VDC and can source up to 200 mA, making it compatible with a broad spectrum of control hardware. The 4‑wire PNP output provides both NO (normally open) and NC (normally closed) contacts, giving engineers flexibility in wiring and logic design. With a robust copper housing, a 30 mm mounting hole, and a 150 cm cable, the unit is engineered for pole‑mount installations where space is limited but performance cannot be compromised.

Usage

Designed for PLC‑controlled automation, this sensor excels in applications such as conveyor monitoring, robotic end‑of‑stroke detection, and safety interlocks for both residential and commercial security systems. Its ability to sense any non‑metallic object makes it ideal for detecting plastic, glass, wood, or composite materials in packaging lines, material handling equipment, and smart home installations. The sensor’s 10‑30 VDC power requirement aligns with standard industrial power supplies, while the 200 mA output can directly drive relay coils or indicator lights without additional driver circuitry. Because the sensor is shielded, it can be placed near high‑current motors, variable frequency drives, and other sources of electromagnetic noise without loss of accuracy. The 150 cm cable provides ample reach from the mounting point to the control cabinet, simplifying wiring and reducing the need for extra conduit.

FAQ

What types of materials can this sensor detect?

The sensor is capacitive, so it can detect any non‑metallic (dielectric) material such as plastic, glass, wood, rubber, and composite parts within its adjustable range.

Can the sensor be used with a standard PLC power supply?

Yes. It operates on 10‑30 VDC, which matches the common voltage levels supplied by most PLC power modules, and its 200 mA output can directly drive relay coils or indicator lights.

Is the sensor suitable for outdoor installations?

While the sensor is designed for indoor industrial use, its copper housing and sealed connector provide a degree of protection against dust and moisture. For outdoor applications, additional enclosure or sealing is recommended.

How do I adjust the detection distance?

The detection distance can be set using the built‑in adjustment screw on the sensor body, allowing fine‑tuning from 0 mm up to the maximum 10 mm range.

What warranty does Heschen offer?

Heschen provides a standard one‑year limited warranty covering manufacturing defects, along with access to technical support for installation and troubleshooting.
