Optical Sensor Detects Particles as Small as 0.3µm
Farnell, an Avnet Company, increased its range of high-quality sensor products with the introduction of the SN-GCJA5, a particulate matter (PM) laser sensor from Panasonic Industry Europe. Designed in response to the increasing worldwide concern for indoor air quality, the SN-GCJA5 is well suited for air quality monitoring, air conditioners, building automation, smart homes, HVAC, air purifiers, Internet of Things (IoT) devices, test and measurement, and environmental monitoring applications.
The SN-GCJA5 Laser Type PM Sensor features an innovative optical assembly to provide reliable operation over a long lifetime while accurately detecting particles as small as 0.3µm. Advanced laser-scattering technology enables the sensor to provide a fast response when detecting smoke, environmental dust, and other unwanted dangerous pollutants. Measuring 37x37x12mm, the SN-GCJA5 can be easily integrated into a wide range of air quality monitoring devices. It offers uncomplicated I²C and UART (TTL) connectivity and challenges conventional LED-based concepts in many areas.

Semtech announced sampling of the latest member of its Tri-Edge CDR portfolio, the GN2256. Integrating Semtech’s Tri-Edge CDR platform with a differential EML (Externally Modulated Laser) driver, the GN2256 is the industry’s first such IC solution to enable 50Gbps PAM4 Fixed-WDM (Wavelength Division Multiplexing), Tunable WDM and Silicon Photonics optical modules. As with all Tri-Edge ICs, the GN2256 offers ultra-low latency, low power and use of low cost 25Gbps bandwidth optics to operate at 50Gbps PAM4.
[Editor's note; we recently talked to Raza Khan, senior marketing manager at Semtech, about the company's 5G front-haul applications here: Integrating 5G into the Wireless Infrastructure.]
The GN2256 combines Semtech’s proprietary analog Tri-Edge technology with enhanced laser driver compensation to enable IEEE and Open Eye MSA compliant optical modules over industrial temperature ranges. Semtech’s Tri-Edge 5G platform addresses the full range of optical modules needed for all regions by enabling multiple types of SFP56 optical modules operating at 50Gbps PAM4.
