Typical crosstalk free range

VDD=2.5V; ILED=200mA; Trep=100ms; glass without ink and a two separate IR transmissive openings for emitter and

detector

Note for crosstalk free range: The displayed crosstalk free ranges for a single or two hole IR transmissive opening are

measured with a clear cover. Depending on the used ink the crosstalk level can differ and needs to be measured. OSRAM

OS provides costumer related application support and measurements – please contact your OSRAM OS marketing or

sales partner, if support is required.

As the measurement results show the typical performance of the sensor OSRAM OS recommends to design inn a additional

safety guard in the distance of the cover bottom surface to the top of the sensor of 200µm. e.g.: for a 0.5mm thick cover

window with two holes and an acceptable crosstalk level of 0 counts the distance of the cover window bottom surface to the

top of the sensor should not exceed 0.6mm (typ. it would be 0.8mm)
