Product Description

​The Panasonic HL-G112-S-J is a high-functionality compact laser displacement sensor from the HL-G1 series, designed for precise distance measurement applications. It offers a measurement range of ±60 mm centered at 120 mm, with a resolution of 8 μm and linearity of ±0.1% F.S. The sensor utilizes a red semiconductor laser (655 nm wavelength) with a maximum output of 1 mW, ensuring accurate detection. It features both voltage and current analog outputs, as well as three programmable judgment outputs (NPN or PNP), and supports communication via RS-422 or RS-485 interfaces. With a robust IP67-rated enclosure, the HL-G112-S-J operates effectively in various industrial environments.
