Guva-s12sd Uv-a Sensor For Uv Index Monitoring
The Guva‑s12sd UV‑A sensor is engineered for accurate UV‑index monitoring in handheld and portable devices. It employs a Gallium Nitride Schottky photodiode that operates in photovoltaic mode, delivering a responsivity of 0.14 A/W at 25 °C. The active area of 0.076 mm² results in a dark current of 1 nA, enabling low‑noise readings. Its detection band spans 240 nm to 370 nm, which aligns with the UV‑A spectrum required for index calculations.
Gallium Nitride provides high electron mobility and resistance to temperature‑induced drift, a typical advantage for sensors used in outdoor equipment. The device tolerates storage temperatures from - 40 °C to 90 °C and operates reliably between - 30 °C and 85 °C, matching industry standards for field‑ready components. Typical packaging for this class includes surface‑mount packages that can be placed on compact PCBs, and the reverse voltage rating of 5 V with a forward current of 1 mA protects the diode during operation. In the UV‑sensor market, a temperature coefficient near 0.08 %/°C and dark current below 5 nA are regarded as standard performance metrics.
This sensor is used by manufacturers of wearable health monitors, portable weather stations, and UV‑lamp control units that need real‑time index data. Buyers often request bulk quantities with flexible minimum order sizes and prefer FOB or CIF shipping from Shenzhen. The sensors are packed in anti‑static trays to prevent electrostatic discharge during transport. Confirm any specific trade conditions directly with Week Technology Ltd.

Sourcing Guva-s12sd Uv-a Sensor For Uv Index Monitoring from Week Technology Ltd. - China Import Guide
Prior to purchase, request the full datasheet to confirm the sensor’s GaN material grade, spectral response, and the dark‑current specification of 1 nA. Ask the supplier to provide any available CE or ISO conformity certificates, as the listing only mentions these standards in general terms. Verify that the anti‑static packaging meets your handling requirements for sensitive photodiodes.
Clarify the preferred Incoterm - many buyers opt for FOB Shenzhen, but CIF to a nearby port can be arranged if desired. Because the supplier’s response metrics are inactive, negotiate payment terms such as T/T against clean documents or an escrow service to protect both parties. Inquire about the typical lead time for bulk production, which may vary with order size.
Arrange a third‑party inspection to check for visual defects and to measure responsivity at 25 °C using a calibrated UV source. Request a test report that includes the temperature coefficient curve and verification of the optical power range. Ensure the supplier supplies a certificate of conformity and a declaration of CE compliance to streamline customs clearance.
