What happens after changing dip switch settings?

The LD-200 must be reset every time a setting change is made to the dip switches to ensure the new configuration takes effect.

What is the frequency range?

The operating frequency can be set between 20 KHz and 100 KHz using the dip switches (Switch 1 D9 & D10 and Switch 2 D6 & D7).

AI-Powered supplier vetting

SummaryShenzhen Jutai Comm Co., Ltd. is identified as a China-based limited company with both trading-company and manufacturer/factory classifications. It offers infrared safety curtain sensors and 24G motion radar sensors, reports ISO 9001 and ISO 14001 certifications, and has factory facilities in Shenzhen. Production evidence includes more than 10 production lines, stated annual microwave motion sensor productivity of 5,000 sets, 6–10 quality-control staff, and R&D engineer experience totaling 21–30 years. The supplier has exported since 2012 and reports that 90% of sales are exports. Its company description claims complete system solutions, technology support, and after-sales service, but most detailed service, customization, R&D documentation, quality-process, and overseas-operation fields are marked unknown. Audit information identifies TÜV Rheinland, but the audit result is recorded as 0 and the report validity shown ended on 2025-12-26; the meaning of the result code is not provided.

Supplier typeThe supplier is described as both a trading company and manufacturer/factory, legally structured as a limited company and located in Shenzhen, Guangdong, China. The associated-company industry is listed as manufacturing, supporting a manufacturing connection, although the records also explicitly classify the business as a trading company.

CertificationsThe supplier reports ISO 9001 and ISO 14001 management-system certifications. A TÜV Rheinland audit is also recorded, but its result is listed as 0 without an interpretation, and the stated report validity ended on 2025-12-26, so current audit validity cannot be confirmed.

After-Sales capabilityThe company description explicitly states that it provides matched after-sales service, comprehensive technology support, and complete system solutions. However, specific operational evidence for inventory service, overseas warehouses, overseas agents or branches, and related service procedures is marked unknown.

R&D capabilityThe supplier states that continuous technology improvement and innovation are part of its R&D concept, and its R&D engineers have 21–30 years of total experience. Detailed evidence for new-product development, ODM, SDK, private-mold design, R&D documentation, and 3D design services is unavailable because these fields are marked unknown.

Production capacityProduction-related evidence includes more than 10 production lines, 6–10 quality-control staff, stated annual productivity of 5,000 microwave motion sensor sets, and a factory location in Shenzhen. The supplier also reports exporting since 2012 and using both agent and self-operated export methods, indicating established operational experience.

Product Q&A

Q:What is the direction recognition function?

The LD200/202 detector identifies the direction of vehicle movement. This prevents the system from triggering twice for the same vehicle, ensuring accurate entry and exit records.

Q:How is sensitivity adjusted?

Sensitivity is adjusted using dip switches. There are 8 selectable levels, with Switches 6-8 for Channel 1 and Switches 3-5 for Channel 2, ranging from 0.015 (most sensitive) to 0.8 (least sensitive).

Q:Can the detector work as two independent channels?

Yes. The LD200/202 can function as two independent single-channel detectors. This mode is ideal for standard one-in/one-out parking lots, reducing hardware costs by using one loop for reader triggering and another for anti-smashing safety.

Q:What are the LED indicators for?

The RED LED indicates power status. CH1 and CH2 LEDs indicate detection status: Continuous ON means vehicle detected, slow blinking indicates a short circuit or insufficient loop twists, and fast blinking indicates an open circuit or too many twists.

Q:How should the loop coils be installed?

Loops should be sealed using quick-set black epoxy compound or hot bitumen mastic to blend with the roadway. During installation, keep the product plug and socket in the vertical direction.
