A new level of detection

August 2009 Sensors & Transducers

ifm electronic’s O1D300 photoelectric sensor is designed to detect the levels of non-dusting and non-transparent bulk materials without contact. Using a visible laser beam the distance sensor detects ranges up to 10 m using the time-of-flight principle.

Two buttons and simple menu guidance enable easy and precise setting of switch points and other parameters. The level of the medium is indicated on the 4-digit LED display, it can also be provided as a scalable analog (4-20 mA) signal.

The award-winning photonic mixer device (PMD) technology enables a particularly compact design (42 x 42 x 52 mm). This system-on-a-chip integrates receiver and signal processing on a single die, the PNP semiconductor switch output can be set as either normally closed or normally open.

The robust die cast zinc housing makes the units ideal for use in especially rough environments. If surfaces are not shiny the allowed angle of incidence of the light is up to 45%deg; for ease of installation.

The O1D300 offers an alternative to conventional ultrasonic sensors through cost effective long range operation and flexible application.
