DESCRIPTION

The CNY65Exi consists of a phototransistor optically

coupled to an infrared-emitting diode in a 4 pin plastic

package. The components are mounted opposite one

another, with a distance between input and output of

> 3.0 mm; meeting the highest of safety requirements.

The CNY65Exi is ATEX certificated for explosive

atmospheres according to the Directive 2014/34/EU
