Optical sensors O-33 / O-34
Optical sensors O-33 / O-34
Description
Maximum Flexibility — Times Two
Compact Optical Sensors of the O-33 / O-34 Series
Performance features, operating principles, and detection ranges are identical across both complete sensor series. The key difference lies in the housing: while the O-33 series features a durable plastic enclosure, the O-34 series comes in a rugged stainless-steel design—ideal for use in harsh environments. The new di-soric photoelectric sensors, equipped with high-resolution CMOS arrays and reliable background suppression, offer detection ranges from zero up to 15,000 mm. Laser sensors using Deviation Detection Mode can detect virtually any object.
With their versatile functionality, exceptional flexibility, and IO-Link–based application reliability, these innovative sensors from the automation specialist di-soric (based in Urbach, Germany) are particularly suited for assembly and handling technology, material feeding systems, and the packaging industry. Thanks to the proven di-soric Plug & Play principle, the sensors are ready for operation in no time and can be intuitively configured without complex adjustments.
With two complete product series and 36 device variants, di-soric covers virtually all optical detection tasks. Featuring a 25.4 mm hole spacing and compact housing dimensions of 30 mm × 20 mm × 11 mm, these sensors require minimal installation space. The O-33 series, made of plastic with IP67 protection, is ideal for a wide range of industrial applications. Where mechanical stress is high or aggressive cleaning agents are used, the robust O-34 stainless-steel sensors (V4A) with IP69K protection and ECOLAB-certified detergent resistance are the perfect choice.
Depending on the application, users can select the right sensor from four operating principles and the required detection range. The diffuse sensors with background suppression of the OH-33 and OH-34 series detect objects up to 1,000 mm away, using either red-light laser or LED sources with ultra-fine, medium, or large light spots. The classic diffuse sensors of the OT-33 / OT-34 series reach up to 1,000 mm with red LED light. Retro-reflective sensors of the OR-33 / OR-34 series operate over distances of up to 6,000 mm, while through-beam sensors achieve reliable detection ranges of up to 15,000 mm.
Unique and currently the smallest triangulation sensors on the market are the OH33/34-LR laser diffuse sensors with background suppression, offering ranges up to 600 mm. Using the teach button, users can set distances, switching windows, and the DD Mode directly on the sensor with a single press. In DD Mode, both distance and light intensity are evaluated simultaneously, allowing detection of nearly all objects against a taught background—an advanced feature previously found only in larger sensor classes.
All sensors are ready to use “out of the box” and come preconfigured with factory settings suitable for many applications. Commissioning can be done directly on the sensor using a button or potentiometer, or centrally via IO-Link. The device can also be configured through one-point teach with a guided blinking sequence. IO-Link provides users with extensive diagnostic functions. The digital communication standard ensures loss-free measurement data transmission, reproducible switch point configuration, and reliable functional safety verification through simultaneous evaluation of measurement and switching data. Values can be displayed in millimeters or as intensity readings.
IO-Link thus provides users with maximum flexibility and application reliability.
