Heschen M30 Capacitive Proximity Sensor Switch NPN NC 10-30V 200mA

Description

Product Overview

The Heschen M30 capacitive proximity sensor is engineered to meet the demanding needs of modern industrial automation. Featuring a robust non‑shielded design, the sensor delivers a reliable NPN normally closed (NC) output that integrates smoothly with PLCs, HMIs, and other control systems. Its 30 mm mounting hole simplifies installation on standard panels, while the adjustable detection range of 0‑18 mm (typical 20 mm ±10%) allows fine‑tuning for various target materials. Operating on a wide voltage span of 10‑30 VDC and delivering up to 200 mA of output current, the device ensures consistent performance even in fluctuating power conditions. The sensor’s ability to detect any dielectric object—such as plastics, glass, wood, and composites—makes it a versatile solution for material handling, level detection, and safety interlock applications.

Usage

Designed for harsh industrial environments, the M30 sensor thrives in applications ranging from conveyor belt monitoring to robotic end‑effector safety zones. Its compact three‑wire configuration (brown, blue, black) enables straightforward wiring to standard input modules, reducing installation time and minimizing wiring errors. The sensor is ideal for detecting the presence of non‑metallic parts on assembly lines, monitoring liquid levels in non‑conductive tanks, and providing proximity alerts in packaging machinery. Because it operates on low power and tolerates temperature variations, it can be deployed in outdoor enclosures, food‑processing facilities, and chemical plants where reliability and cleanliness are paramount.

FAQ

What types of materials can the sensor detect?

The M30 uses capacitive sensing, which responds to changes in dielectric constant. It can reliably detect plastics, glass, wood, ceramics, and other non‑metallic objects, making it suitable for a broad range of industrial tasks.

How do I adjust the detection distance?

Adjustment is performed by turning the built‑in potentiometer on the sensor housing. Turning clockwise shortens the sensing range, while counter‑clockwise extends it up to the specified maximum of 20 mm. Calibration should be done with the target material present to achieve optimal performance.

Is the sensor suitable for harsh environments?

Yes. The M30 is built with a rugged housing that resists dust, moisture, and temperature extremes. It complies with IEC 60529 IP65 standards, allowing installation in dusty factories, humid processing areas, and outdoor enclosures.

Can the sensor be integrated with existing PLC systems?

Absolutely. Its NPN normally closed output matches the input requirements of most PLCs and safety controllers. The three‑wire connection (power, ground, and signal) follows standard wiring conventions, enabling plug‑and‑play integration.

What warranty and support are provided?

Heschen Electric offers a one‑year limited warranty covering manufacturing defects. Our technical support team is available via phone and email to assist with installation, troubleshooting, and firmware updates throughout the warranty period.
