Marktech reflective sensors feature 0.5-1.5mm short detection distance


Marktech Optoelectronics has announced the expansion of its surface-mount family of SWIR reflective sensors.

The sensors are suitable 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 sensor is reflected back to the detector side as an object enters the sensing area, with an optimal short detection distance of 0.5-1.5mm.

The series is offered in six standard models, each with its own peak emission wavelength from 1040-1625nm. They are offered in 4-pad SMD black moulded 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 5.1×3.3mm. Units are both REACH and RoHS compliant.

Small-to-medium sized quantities of standard surface-mount SWIR reflective sensors are typically available with 24-hour shipment from stock through Digi-Key Electronics. Sensor customization is also available upon request, in quantities ranging from prototypes to OEM volumes.
