Zero-Field Atomic Magnetometer QZFM Gen-3
The source announces the release of QUSPIN's third-generation QZFM sensor Gen-3, completing the final stage of its three-step development of mature zero-field OPM technology. Gen-1(2016) was a proof-of-principle prototype. Gen-2(2019) prioritized user comfort and miniaturization for dense multichannel imaging. Gen-3(2021) resolved the preceding generations' issues and integrated the technology into a powerful platform for practical problems. Gen-3 includes several upgrades, but prioritizes a robust, reliable sensor for future biomagnetic imaging systems.

ZTOF-4424-10A-Z45 Sensors Zgy-led
Dimensions: 4.4 mm × 2.4 mm × 1.0 mm Detection distance: 2cm~5m Detection Accuracy [Indoors]: ±3%
The ZTOF-4424-10A-Z45 is a highly integrated, compact single-point dTOF (direct Time of Flight) sensor. It integrates a VCSEL emitter, single-photon avalanche diode (SPAD) array, microlenses, TDC (Time Digital Converter), and MCU. dTOF technology and built-in sunlight-rejection and cover-contamination algorithms maintain measurement accuracy independently of target reflectance in varied environments, enabling precise ranging up to5m. The ZTOF-4424-10A-Z45 supports firmware updates through IIC, with modes and algorithms customizable to customer needs. An eye-safety control circuit meets Class I requirements. 1.Product Dimensions:the ZTOF-4424-10A-Z45 uses a12-pin LGA package measuring4.4mm (±0.05mm) x2.4mm (±0.05mm) x1.0mm (±0.075mm); unspecified tolerance is±0.05mm. 2.PCB Pad Dimensions:Figure11, PCB pads, top view. 3.Application Circuit:ZTOF-4424-10A-Z45 block diagram. Notes:1.The external AVDD capacitor should be as close as possible to the AVDDVCSEL and AVSSVCSEL pins. 2.HOST must always drive XSHUT; use a pull-up if host state is unknown. XSHUT requires HW standby mode without IIC communication. Soldering and Storage:1.Soldering Requirements:recommended reflow peak240ºC~260ºC, never exceeding260ºC. The source references a lead-free SMT profile and parameters:Figure13,recommended reflow profile;Table13,recommended oven-temperature test controls. Notes:1.Temperatures are measured at the package top. 2.Maximum reflow cycles:three. 2.Storage Instructions:ZTOF-4424-10A-Z45 is supplied in sealed moisture-barrier bags, with moisture sensitivity level3 (MSL3). Moisture absorbed during packaging can be released and evaporated during soldering, adversely affecting optical characteristics. Each device is baked before dry packing to minimize moisture. Sealed aluminized bags protect against ambient humidity during shipping and storage. Shelf Life:an unopened bag provides12 months from its marked date under the stated conditions:Shelf Life12 months;Ambient Temperature<40℃;Relative Humidity<90%. Beyond12 months, or if the humidity indicator shows excessive storage humidity, rebake the device. Floor Life:ZTOF-4424-10A-Z45 has MSL3 sensitivity, giving168 hours from bag opening under these conditions:Floor Life168 hours;Ambient Temperature<30℃;Relative Humidity<60%. Exceeding floor life or these conditions requires rebaking before reflow or dry packing. Baking:125±5℃ for8 hours;do not bake directly in carrier tape;avoid excessive vibration or impact that could seriously deform or damage packaging. IIC Communication:device address0x41, or0x82 when adding a1bit read/write bit to form8bit;maximum transfer speed1Mbits/s.
