The EE-SX4088 is a Light ON type transmissive photomicrosensor that integrates a detector element and amplifier into a single IC chip. It operates on a wide supply voltage range from 4.5 to 16 VDC and features a high resolution with a 0.5-mm-wide sensing aperture. The sensor has a minimum response frequency of 3 kHz and its emitter has a peak emission wavelength of 940 nm. This device can be directly connected to C-MOS and TTL logic. Due to its high resolution and fast response, this photomicrosensor is well-suited for applications requiring precise object or position detection in automation and office equipment.
