ISSR 0.15M 400kHz Ultra-high Precision Short-Form Ultrasonic Distance Sensor

The ISUB150 Series represents the pinnacle of short-range ultrasonic sensing technology, engineered for industrial applications where space is limited but precision cannot be compromised. Featuring an ultra-short M18 nickel-plated brass housing (length approx. 40mm) and a high-frequency 400 kHz transducer, this sensor delivers reliable detection of liquids, solids, and granular materials regardless of color or transparency.

With a detection range of 20...150 mm and a minimal blind zone of just 20 mm, the ISUB150 is the ideal solution for precise distance measurement and object detection in compact machinery.

Why Choose the ISUB150 Series?

1. Ultra-Compact "Short Form" Design
Unlike standard M18 sensors that can be cumbersome in tight spaces, the ISUB150 features a significantly reduced housing length. This "Short Form" design allows for seamless integration into robotic arms, small conveyor systems, and packaging machinery without sacrificing durability.

2. Superior Precision and Stability
Leveraging high-frequency 400 kHz ultrasonic technology, this sensor achieves:

High Resolution: Up to 0.3 mm, allowing for the detection of minute changes in position.
Exceptional Linearity: Within ±1% of the full-scale value.
Temperature Compensation: Built-in compensation ensures measurement stability across a wide operating temperature range (-25℃ to 70℃), minimizing drift caused by environmental changes.

3. Versatile Output Options for Any Controller
To match your specific PLC or control system requirements, the ISUB150 series offers three distinct output configurations:

Current Output (Model -I): 4-20 mA analog output for precise continuous measurement.
Voltage Output (Model -U): 0-5 V/10V analog output for voltage-based control systems.
Switching Output (Model -E): NPN/PNP switching for reliable presence/absence detection.

4. Industrial-Grade Durability
Built to withstand harsh industrial environments, the sensor features an IP67 protection rating, making it fully resistant to dust ingress and immersion in water. The robust nickel-plated brass housing provides excellent mechanical strength and corrosion resistance.

Key Applications

Due to its small blind zone and high precision, the ISUB150 is widely used in:

Liquid Level Monitoring: Precise level detection in small tanks, test tubes, or vials.

Print & Packaging: Roll diameter measurement and web tension control.

Electronics Assembly: PCB stack height measurement and component presence verification.

Material Handling: Detection of transparent objects (glass, plastic film) that optical sensors often miss.
