About Nanyang Senba Optical & Electronic Co., Ltd. - Electric Sensors Supplier in China

Nanyang Senba Optical & Electronic Co., Ltd. is based in China and currently lists five active products. The catalogue is divided between electric sensor components and related optical items, reflecting the company’s focus on sensor technology and agricultural applications. The product list includes the Senba D203S PIR sensor, the D204S pyroelectric infrared radial sensor, the GL35 series CDS photoresistor, an analog linear coupling unit, and a 46 mm optical Fresnel lens. Each entry is presented under the broader categories of electric sensors and agricultural optics, matching the supplier’s declared top categories.

Product Range and Specialties of Nanyang Senba Optical & Electronic Co., Ltd.

The Senba D203S PIR sensor is a passive infrared device used for motion detection in security and automation systems; typical PIR modules operate in the 8‑12 µm wavelength band and offer detection ranges of 5‑10 m. The D204S pyroelectric infrared radial sensor is a pyroelectric detector that responds to temperature changes, commonly specified by responsivity (µV/(W/cm²)) and a response time under 50 ms. The GL35 series CDS photoresistor is a light-dependent resistor with resistance varying from several kilo‑ohms in bright light to mega‑ohms in darkness, often supplied in standard 5 mm or 7 mm diameters. The analog linear coupling component provides linear voltage or current transfer with typical linearity error below 0.5 % and bandwidth up to 1 MHz. The 46 mm optical Fresnel lens is a thin, concentric‑groove lens used to focus or collimate light, commonly fabricated from polymer or optical glass with a focal length around 46 mm and transmission above 90 % in the visible spectrum. Industry standards for these items include IEC 60950 for safety, IEC 60730 for sensor performance, and RoHS limits on restricted substances.

Trade and Export Information - Nanyang Senba Optical & Electronic Co., Ltd.

China is a leading exporter of electronic sensor modules and optoelectronic components, supplying North America, Europe, and Southeast Asian markets. Buyers of PIR and pyroelectric sensors typically require compliance with CE marking, RoHS, and IEC safety standards, and they often request test reports such as IEC 60730 performance certificates. Optical components like Fresnel lenses are commonly shipped in anti‑static poly‑bags or molded pulp cartons to protect surface quality, with container loads ranging from 20 ft to 40 ft depending on volume. Export logistics from China frequently use FOB or CIF Incoterms, and freight forwarders advise on moisture barrier packaging for photoresistors to maintain stable resistance values during transit.

Sourcing from Nanyang Senba Optical & Electronic Co., Ltd. - Buyer Guidance

When sourcing from Nanyang Senba, request the latest datasheets and test reports that confirm CE, RoHS, and IEC compliance for each sensor type. Verify the detection range, responsivity, and linearity specifications against your application requirements before placing an order. Ask for a sample unit packaged in anti‑static material and include a calibrated reference sensor to compare performance under identical test conditions. Confirm the supplier’s packaging details, such as moisture‑proof bags for photoresistors and padded containers for the Fresnel lens, to avoid damage during shipment.

What types of infrared sensors does Nanyang Senba offer?

The catalogue includes a passive infrared (PIR) sensor model D203S for motion detection and a pyroelectric infrared radial sensor model D204S that detects temperature variations.

Are the sensors compliant with international safety standards?

The supplier does not list certifications, so buyers should request CE marking and IEC 60730 test reports to confirm compliance.

What is the typical resistance range for the GL35 series CDS photoresistor?

The GL35 series typically varies from a few kilo‑ohms under strong illumination to several mega‑ohms in darkness, depending on light intensity.

What material is the 46 mm optical Fresnel lens made from?

Fresnel lenses of this size are usually manufactured from optical‑grade polymer or glass; buyers should request a material specification sheet to confirm.

What packaging is used for the analog linear coupling component?

Standard practice is to pack the coupling in anti‑static bags within a cushioned cardboard box to protect the linearity characteristics during transport.

What are common lead times for these sensor products?

Lead times for electronic sensor components from Chinese manufacturers typically range from 2 to 6 weeks, depending on order size and required testing.

Can I request a sample before placing a bulk order?

Yes, buyers can ask for a single unit of each sensor type, packaged in anti‑static material, to evaluate performance against their specifications.

Which Incoterms are usually applied to shipments from this supplier?

Export transactions often use FOB (Free on Board) or CIF (Cost, Insurance, Freight) terms, allowing the buyer to choose the most suitable logistics arrangement.
