Laser fork and angled-light barriers with IO-Link
The OGUL series laser fork light barriers and the OGLL series laser angled light barriers are particularly suitable for the detection of small parts. Both series have the eye-safe laser class 1.
Ready to run and quickly set up
Fast start-up due to 4 sensor modes and the highly visible laser dot, which enables fast adjustment even in bright environments. The collimated laser red light ensures high accuracy of the switching point over the entire fork width.
The OGUL series available with fork openings of 30, 50, 80 and 120 mm is the best solution when the goal is process-reliable and fast detection of very small objects down to a size of just 0.03 mm.
With OGUL, the position and alignment of thin wires, drill bits or cannulae can effortlessly be defined down to a (reproducible) accuracy of 0.01 mm.
Benefits of the precise
OGUL Laser / OGUL Laser Stainless steel:
Fast, reliable detection of the smallest parts with a high functional reserve
4 pre-configured sensor modes:
Standard mode is the default – the High Resolution, Speed and Power modes can be selected via IO link
Preferred fields of application:
Detection of very small parts in assembly, handling and packaging technology, as well as quality control
Robust, powder-coated metallic housing or cleanroom-compatible V4A stainless steel housing for areas with strict requirements for hygiene and resistance to cleaning agents – both in the high protection class IP67
OGUL lasers work reliably and with high process safety in a temperature range between –25 °C and 60 °C

Position monitoring: groove present?
The correct position of cylindrical components is verified by checking for the presence of a small groove. Our OGUL laser fork light barrier features a clearly visible laser beam and handles this task with functional reliability.
In the NC position of the potentiometer, the switching output is switched off if no groove is present, and the product can be rejected.
A feeding unit transports disposable syringes in a hanging position to their final assembly station at a high speed. A rotary table is used to fit plastic caps on the syringes. Before this table, the needles pass through a laser fork light barrier from the OGUL series. The thin needle has to be detected as present before the system is allowed to put the cap on.
The challenge in this application: the cannula measures 0.3 mm, so the cycle times are short. Users in the clinical sector rely on the presence of a fully functional disposable syringe in every package.

Detection of rapid-cycle objects down to a size of 0.03 mm
The OGLL series is the best solution when the goal is process-reliable and fast detection of very small objects down to a size of just 0.03 mm. With OGLL laser angled light barriers the position and alignment of thin wires, drill bits or cannulae can effortlessly be defined down to a (reproducible) accuracy of 0.01 mm.

Checking connector contacts
At a supply unit that feeds an assembly machine, a laser angled light barrier from the OGLL series is used in narrow installation spaces. It checks supplied components to see whether the very thin connector contacts are present.
The high resolution of the laser sensor guarantees that even extremely thin wires are detected with certainty. The easily visible laser light spot allows the sensor to be aligned and adjusted quickly and precisely.
