Overview
The CGQ-024A is the input a cab uses for automatic wipers and automatic headlamps. A wiper and lighting controller owns those decisions.

Choosing: light-and-rain versus ambient light
The CGQ-024A adds a rain-detection channel to the light reading.
The CGQ-012A is an ambient-light sensor assembly: a domed housing with a low-level ambient-light output on pin 2 and a 5 V supply. Where the controller only needs that light input, its page carries the six-pin definition. CGQ-024B-SYN is a separate part on the same catalogue page, with its own connector. These parts are quoted through the same OEM workflow. For the full sensor line, see how we work as a commercial vehicle sensor manufacturer.
Manufacturing and testing
Built under IATF 16949 with APQP project planning and a PPAP package available for OEM programmes. End-of-line testing checks the light and rain channels against reference points before packaging. EMC and temperature validation is run on a sample basis in our in-house lab when a programme requires fresh data.
How to ask
The CGQ-024A belongs to the Switches & Sensors family. For an ambient-light input only, see the CGQ-012A ambient-light sensor; for the wider sensor programme — TPMS, rain-light and fuel-level — talk to us as your commercial vehicle sensor manufacturer, and the rain and light sensor buyer guide explains how automatic wipers and headlamps use these sensors. To request the output behaviour or a fleet-grade configuration, use the contact page. These help if you already have them: target vehicle programme, expected annual volume, and key requirements (glass at the installation area, auto-wiper / auto-lighting targets). Drawings welcome.
