Marktech Expands Surface-Mount SWIR Reflective Sensors Family

Posted Oct 09, 2019 by Marktech Optoelectronics

Marktech Optoelectronics has announced the recent expansion of its industry-exclusive surface mount (SMD) SWIR reflective sensor family. The superior alignment and sensitivity of Marktech’s surface mount SWIR reflective sensor offerings make them ideal for position sensing and detection applications, including card, barcode, edge sensing and money bill readers.

Marktech surface mount SWIR reflective sensors combine both a short wavelength infrared emitter and a high-sensitivity InGaAs photodiode. Emitted light from the Marktech sensor is reflected back to the detector side as an object enters the sensing area, with an optimal short detection distance of 0.5 to 1.5 mm. The series is offered in six standard models, each with its own unique peak emission wavelength from 1040 to 1625 nm.

Each element is spectrally and mechanically matched and then seamlessly integrated within a single, compact, 4-pad SMD black molded housing. The black housings are designed to help reduce the risks of measurement uncertainty created by external ambient light effects. The series’ overall footprint measures just 5.1 mm x 3.3 mm, facilitating its ease of installation within space constrained environments. Units are both REACH and RoHS compliant.

Small-to-medium sized quantities of standard surface mount SWIR reflective sensor models are typically available with 24-hour shipment from stock via Marktech’s longtime distribution partner, Digi-Key Electronics. Sensor customization is also available upon request, in quantities ranging from prototypes to OEM volumes. Full production volumes are typically available within just 6-8 weeks from customer prototype approvals.
