Omron has extended its range of integrated amplifier products to include photoelectric sensors with M8 and M12 cylindrical housings. Featuring a compact metal housing, the new E3H2 sensors are suitable for applications where space restrictions prevent the use of the company’s easy-mount M18 units. The M8 versions of the new sensors are through-beam units, while the M12 versions are available in through-beam, retro-reflective and diffuse-reflective models.
All models can be supplied in pre-wired or connector versions with either NPN or PNP outputs. The M12 units are user configurable for dark-on or light-on operation, while M8 types are offered as separate light-on and dark-on models.
Through-beam M12 sensors in the E3H2 family have an sensing range that is adjustable up to a maximum of 4 m. For fast easy set up, the retro-reflective versions, which have a maximum range of 2m, feature a teach facility that can be accessed locally or remotely. Using this facility, the units can optionally be programmed for high-sensitivity operation, which allows them to provide reliable sensing of semi-transparent targets.
The M12 diffuse-reflective sensors are available in teachable versions with a maximum range of 300 mm, and in fixed sensitivity versions with a range of 100mm. The M8 through-beam sensors have a sensing range of 2m.
All of Omron’s new E3H2 photoelectric sensors are designed for use with nominal 24Vdc supplies, and all have transistor outputs rated at 100 mA. The sensors have an operating temperature range of -25ºC to +55ºC (-25ºC to +50ºC for M8 types) and an IP67 ingress protection rating.
