MAXREFDES27 IO Link Optical Proximity Sensor System Board

The MAXREFDES27# is a tiny IO-Link proximity sensor with an IR receiver, matching IR LED driver, IO-Link transceiver, and energy-efficient step-down converter all on an 8.2mm x 31.5mm printed circuit (PC) board. Maxim Integrated and Technologie Management Gruppe Technologie und Engineering (TMG TE) collaborated in designing the MAXREFDES27# as an IO-Link version 1.1/1.0 compliant proximity sensor reference design. The MAXREFDES27# design consists of an industry standard Maxim Integrated IO-Link device transceiver (MAX14821), a tiny low-dropout linear regulator (MAX8532), an efficient high-voltage step-down converter (MAX17552), a Renesas ultra-low-power 16-bit microcontroller (RL78) utilizing TMG TE"s IO-Link device stack, and a Maxim Integrated proximity sensor (MAX44000).
