SICK 6063342 GLL170T-B333 M8 Teach-in Fiber Amplifier

Technical Overview

The SICK GLL170T-B333 is a stand-alone fiber-optic amplifier using a 632 nm red LED and a separately selected optical fiber for the sensing task. Local buttons provide one-point, two-point and zone teaching, while the four-digit display shows received-light information or parameters. One open-collector output is selectable as PNP or NPN, with menu selection of light/dark operation, standard ≤250 µs or fast ≤50 µs response, and delay or one-shot timing. The M8 three-pin connection carries supply, ground and Q; this variant has no external teach input. Its 10–30 V DC PC/POM unit supports rail or fixing-hole mounting and IP66 with correctly attached LL3 fibers.

Industrial Applications

1. Checking a small component in a restricted assembly space

An assembly fixture can place a compatible proximity fiber head near a small component while mounting the amplifier where its display and buttons remain accessible. Two-point teaching records the component and background light conditions, establishing a threshold between them. External assembly logic samples Q after placement, with the selected fiber geometry, target return and working distance assessed during commissioning.

Problem Solved

A taught component-versus-background condition supplies external assembly logic with a presence reference while the selected fiber head brings optical access into the restricted fixture space.

Component presence Two-point teaching Separate fiber head

2. Counting separated features with a through-beam fiber arrangement

A compact feed mechanism can connect compatible through-beam fibers to the amplifier and pass separated features through their optical path. Local teaching establishes the received-light threshold, and the fast response option supplies switching events to an external counter. The installation evaluates the chosen fiber range, feature width, spacing and receiver timing rather than assigning a universal sensing distance to the amplifier.

Problem Solved

Optical interruptions provide feature-passage events for external counting logic, with remote fiber placement and selectable fast response supporting timing assessment at the compact feed path.

Through-beam counting Fast response External counter

3. Comparing a presented surface with a taught received-light zone

An inspection fixture can hold a consistent component surface at a controlled distance from a compatible proximity fiber head. Zone teaching establishes upper and lower received-light thresholds around a reference, and manual adjustment adapts that interval to representative samples. External inspection logic evaluates the single output as an optical-condition check, accounting for surface angle, position and contamination rather than treating the zone as a distance measurement.

Problem Solved

A bounded received-light condition helps external inspection logic distinguish a presented surface from the taught optical reference interval, supporting comparative inspection under controlled presentation and illumination.
