How many of these distance measurement challenges have you encountered in industrial sites?

Inconsistent accuracy, making critical measurements unreliable.

Frequent maintenance that consumes time, labor, and cost.

Strict installation requirements that make on-site deployment difficult.

If these pain points sound familiar, today’s new product — the KJT-LD18 Compact Radar Sensor from KJT — is well worth your attention.

What Are the Pain Points of Traditional Radar Sensors?

❌ Unstable accuracy — unreliable measurements at critical moments.
❌ High maintenance costs — frequent calibration that wastes time, labor, and money.
❌ Difficult installation — demanding installation conditions and poor on-site adaptability.

The KJT-LD18 is designed to break through these limitations.

Compact Power in the Palm of Your Hand

With a fingertip-sized body, it delivers millimeter-level measurement accuracy.

Industrial design can also be elegant.

Ultra-Compact Size for Narrow Spaces

Only 18 mm in diameter and 89 mm in length.

For precision equipment and space-limited applications, installation position is no longer a compromise.

Two Core Advantages: Extreme Reliability + Intelligent Connectivity

Extreme Reliability

Measurement range: 1–20 m, customizable.

IP67 protection, with selected models reaching IP68/IP69K.

Operating temperature: -40°C to +65°C, reliable in both extreme cold and heat.

Power consumption: less than 2.1 W, energy-saving and efficient.

Intelligent Connectivity

Built-in IO-Link communication.

Remote parameter configuration, real-time diagnostics, and predictive maintenance.

Flexible output options: analog output, switching output, RS485, and IO-Link.

122 GHz High-Frequency FMCW Radar Chip

Small in size, powerful in technology.

The KJT-LD18 is equipped with the self-developed Radarium™ 122G radar chip and uses high-frequency FMCW, Frequency Modulated Continuous Wave, technology.

Key benefits:

Dust, water mist, light changes, and temperature fluctuations do not affect its judgment.

Measurement error is reduced to within ±1 mm, with repeatability of less than 1 mm.

Installation Revolution: From “Drilling Holes” to “No Penetration Required”

Greatly Reduces Installation Complexity and Overall Cost

Traditional method: holes must be drilled in the tank body, creating concerns about sealing, corrosion, and high-risk maintenance.

KJT-LD18: installed directly on the outer wall of the container, for non-conductive materials, with no drilling, no structural damage, and no risk of sealing failure.

Overall cost reduced by 80%.

Non-contact measurement monitors from the outside, fully solving corrosion-related challenges and improving safety.

Applications: Millisecond Response, Reliable Even in Water Mist and Dust

Tunnel Car Wash Systems

Millimeter-level accuracy and millisecond-level response ensure stable detection even in water mist environments.

More application scenarios:

Material level monitoring, with no drilling required on tanks.

AGV anti-collision and obstacle avoidance.

Construction machinery positioning.

Outdoor security detection.

Accuracy is the only standard.
