Product Description

Proximity sensor switch is a displacement sensor with switching output. It can detect metal (iron, steel, copper), plastic, glass, wooden, water, paper, magnetic, and other transparent or opaque objects.

Inductive Type: Detects metal objects like Iron, Steel, and Copper.
Capacitive Type: Detects any object including glass, water, oil, and paper.

Widely used in machinery, textile, light industry, papermaking, printing, and packing industries. Compatible with PLC, servo controllers, frequency inverters, and counters for automatic signal input control.

Sensors Summary
Frequently Asked Questions (FAQ)
1. What is the difference between NPN and PNP output?
NPN output provides a negative signal (ground) when triggered, while PNP output provides a positive signal (VCC). The D-A73 model primarily utilizes NPN mode.
2. Can this sensor detect non-metallic objects?
Inductive types are designed for metal detection (Iron, Copper, etc.). For non-metallic objects like glass or plastic, a capacitive proximity sensor is recommended.
3. What does the IP44 and IP67 rating mean?
IP44 provides protection against solid objects over 1mm and water splashes. IP67 models offer complete dust protection and resistance to immersion in water.
4. Is the sensing distance adjustable?
The rated distance (e.g., 2mm or 4mm) is fixed for standard inductive sensors based on the model chosen and the target material size.
5. Can I connect this sensor directly to a PLC?
Yes, these sensors are designed to connect directly with PLCs, servo controllers, and counters to provide automatic signal control.
6. What is the operating temperature range?
The standard operating temperature range for these proximity sensors is between -20ºC and +70ºC.
