Capacitive Proximity Sensor Switch GoHz M30 Unshielded AC 2‑Wire NO

Description

Product Overview

The GoHz M30 capacitive proximity sensor switch is engineered for precision detection across a broad spectrum of materials, including non‑metallic substances, metals, plastics, liquids, and powders. Featuring a robust M30 threaded housing, the sensor is available in both shielded and unshielded configurations, with AC 2‑wire and DC 2‑wire power options, and selectable PNP or NPN output types. The NO (Normally Open) contact mode ensures reliable actuation when the target material enters the sensing field, while the integrated red LED provides immediate visual feedback of the sensor status. Designed for industrial environments, the unit complies with IEC standards for vibration resistance, dust and water ingress protection, and includes reverse power and short‑circuit safeguards to extend service life.

Usage

This sensor excels in a variety of automation scenarios. It can be mounted on conveyor belts to monitor material flow, installed on packaging lines to verify container fill levels, or integrated into robotic end‑effectors for object detection. The AC 2‑wire version simplifies wiring in legacy control panels, while the DC options support modern PLC architectures. Its compact size allows placement in confined spaces such as machine tool enclosures, and the shielded variant reduces electromagnetic interference in high‑noise environments. Typical applications include metal detection in scrap processing, liquid level monitoring in tanks, powder height sensing in pharmaceutical dosing, and plastic part verification in injection molding.

FAQ

What is the difference between shielded and unshielded versions?

Shielded sensors include an additional metal barrier that reduces electromagnetic interference, making them ideal for environments with high electrical noise. Unshielded models are more cost‑effective and suitable for cleaner installations where interference is minimal.

Can the sensor be used with both AC and DC power supplies?

Yes. The product line offers AC 2‑wire and DC 2‑wire variants, allowing you to select the power type that matches your control system architecture without needing additional converters.

What output types are available?

The sensor is offered with both PNP and NPN output configurations, and each can be ordered in Normally Open (NO) or Normally Closed (NC) contact modes, providing flexibility for different PLC input requirements.

Is the sensor suitable for hazardous areas?

While the sensor includes dust and water protection, it is not rated for explosive atmospheres. For hazardous locations, a sensor with ATEX or IECEx certification should be selected.

How does the LED indicator work?

The integrated red LED lights up when the sensing field is triggered, giving a clear visual cue that the target material has been detected. This aids in quick troubleshooting and verification during installation.
