Ultrasonic reflective sensor PNP 10...30VDC M12x1 connector QS18UPAQ8

Ultrasonic sensor for precise object detection

This ultrasonic sensor, catalog number QS18UPAQ8, is a reliable solution for object detection in a wide range of industrial and automation applications. It uses ultrasonic waves to precisely measure distance, regardless of the object's color, shape, or material. Its compact design and robust construction make it ideal for operation in harsh conditions.

Characteristics and application

The sensor operates in a detection range of 50 to 500 mm, making it a versatile tool in many applications. Equipped with an M12x1 connector, it ensures easy and quick integration with existing systems. With a supply voltage of 10...30VDC, it is compatible with most standard electrical installations. A PNP output (normally open – NO) simplifies integration with control systems.

The sensor finds application in:

• Object counting systems
• Detection of object presence on production lines
• Level control of liquids or bulk materials
• Positioning and distance measurement
• Automatic doors and gates
• Robotics and industrial automation

Construction and product features

The sensor has been designed with durability and reliability in mind. The ABS housing provides resistance to mechanical damage and external factors. The implemented protections against polarity reversal and overvoltage protect the device against failures caused by incorrect connection or disturbances in the electrical network. Additionally, the sensor has a short-circuit output protection, which increases its safety of use. An LED indicator informs about the device's operating status, facilitating diagnostics and servicing.

Additional advantages:

• Wide supply voltage range (12-30 VDC): Ensures compatibility with various control systems.
• PNP output: Enables easy integration with logic circuits.
• Compact dimensions: Facilitate mounting in tight spaces (diameter 18mm, length 49mm).
• High ultrasonic frequency (300 kHz): Guarantees precise measurements even with rapid distance changes.
• Wide operating temperature range (-20°C to +60°C): Allows operation in difficult environmental conditions.
• Protection class IP67: Provides resistance to dust and water ingress, enabling operation outdoors.
