描述 Description

The HFBR-0508Z Series consists of a fiber-optic transmitter and receiver operating at a 650nm wavelength (red). The HFBR-1528Z transmitter is an LED in a low cost plastic housing designed

to efficiently couple power into 200μm diameter HCS and 1mm diameter POF. The HFBR-2528Z

receiver incorporates a PIN detec tor and digital output IC compatible with CMOS and TTL logic

families.
