Photoelectric sensors

Baumer Photoelectric sensors / O300 Page 1 ⍾ Baumer ⍾ Last modified May 31, 2026

The Baumer Photoelectric sensors / O300 catalog features a range of sensors including through beam, light barrier, diffuse, retro-reflective, and SmartReflect models. These sensors utilize pulsed LED or laser diode technology, often incorporating qTeach functionality and IO-Link communication. They typically operate within a sensing range of 30 to 300 mm, with some models extending up to 40 m, and are generally equipped with M8 3-pin connectors and operate within a temperature range of -25 to 60 °C, with IP67 or IP68/69K protection.
