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

The ISUB150-18GM40 Series represents the pinnacle of compact automation technology, engineered for industrial applications where installation space is severely limited but precision cannot be compromised. Featuring an ultra-short M18 nickel-plated brass housing (measuring just ~40mm in length) and a high-frequency 400 kHz transducer, this Short Range Ultrasonic Sensor delivers flawless detection of liquids, solids, and granular materials—completely unaffected by target color, transparency, or surface sheen.

With a highly focused detection range of 20 to 150 mm and an industry-leading minimal blind zone of just 20 mm, the ISUB150 seamlessly fits into cramped machinery while providing exact distance measurements.

Why Choose the ISUB150-18GM40 Series?

1. Ultra-Compact "Short Form" Architecture
   Unlike standard, bulky M18 sensors that cause layout headaches in tight spaces, the ISUB150's 40mm shortened body is tailor-made for confined configurations. It integrates effortlessly into robotic arms, miniaturized conveyor systems, and densely packed machinery without sacrificing industrial durability.
2. Superior Precision & Environmental Stability
   Harnessing a powerful 400 kHz acoustic beam with a narrow ±6° angle, this sensor guarantees top-tier performance:
   • High Resolution: Down to 0.3 mm, capturing even the most minute positional changes.
   • Rapid Response: Less than 50ms response delay for high-speed automated lines.
   • Exceptional Linearity: Consistently accurate within ±1% of the full-scale value.
   • Intelligent Temperature Compensation: Maintains stable measurements across extreme operating temperatures (-25℃ to 70℃), actively minimizing drift caused by environmental fluctuations.
3. Versatile Output Options for Any Controller
   Operating on a standard 20-30V DC supply, the ISUB150 series offers multiple distinct output configurations to seamlessly match your PLC or control system:
   • Analog Current (-I): 4-20 mA output for precise, continuous distance monitoring.
   • Analog Voltage (-U): 0-5V or 0-10V outputs for voltage-based control environments.
   • Switching Output (-E): Reliable NPN/PNP configurations for fast presence/absence verification.
4. Rugged Industrial-Grade Durability
   Built to survive harsh manufacturing environments, the sensor carries an IP67 protection rating, ensuring full resistance to dust ingress and water immersion. The robust nickel-plated brass housing provides outstanding mechanical strength and corrosion resistance.

Key Industry Applications

Because of its exceptionally small blind zone and highly focused beam, the ISUB150 excels in specialized and challenging tasks:

• Pharmaceutical & Beverage Packaging: Functioning as a highly reliable Small Bottle Level Sensor, it provides precise, Non-contact Liquid Level Detection in tiny tanks, test tubes, and vials where sanitary conditions are required and standard sensors fail to fit.
• Electronics Manufacturing: Acting as a flawless PCB Detection Sensor, it accurately measures stack heights and verifies component presence on assembly lines, easily ignoring the complex colors, holes, and reflections of modern circuit boards.
• Advanced Material Handling: The perfect solution for detecting difficult transparent objects—such as glass plates or clear plastic films—that frequently trick traditional optical sensors.
