Product Description

The Keyence CZ-H37S is a compact reflective sensor head designed for precise color detection in industrial automation applications. It features a small spot size of approximately 1 mm in diameter at a reference distance of 16 mm, enabling accurate detection of minute color variations. The sensor head utilizes RGB LED light sources—red (665 nm), green (520 nm), and blue (465 nm)—to enhance color discrimination capabilities. With a recommended detection area of 15 mm, it offers versatility in various detection scenarios. The CZ-H37S is constructed with a combination of triacetate and polyarylate housing, complemented by a fiberglass-reinforced plastic lens cover, ensuring durability and resistance to environmental factors. Its IP40 enclosure rating provides protection against dust ingress, making it suitable for industrial environments. The sensor head operates effectively within an ambient temperature range of -10 to +55°C and can withstand ambient light conditions up to 20,000 lux, including direct sunlight. Designed for use with the Keyence CZ-V20 series amplifier units, the CZ-H37S offers a reliable solution for precise color detection tasks.
