The GLL170T-B333 is a stand-alone fiber-optic amplifier from SICK, operating on a sensing principle that depends on the type of fiber-optic cable attached. The unit supports user-selectable PNP or NPN digital output (configurable via on-device menu), a switching frequency of up to 10 kHz, a response time of ≤ 50 µs, and an IP66 ingress protection rating – making it well-suited for precise object detection in electronics manufacturing, food & beverage processing, textile production, and a wide range of industrial automation applications.
Product Overview – GLL170T-B333 SICK Fiber Optic Sensor
The GLL170T-B333 belongs to SICK’s GLL170 series – one of the most widely deployed fiber-optic amplifier families in industrial automation. As a stand-alone unit, the device integrates all signal processing electronics, a parameter display, and configuration push-buttons into a compact housing measuring just 10 × 31.7 × 72.5 mm.
A key differentiator of the GLL170T-B333 is its ability to switch between PNP and NPN output modes directly via the on-device menu, combined with selectable Light/Dark switching modes. This ensures seamless interfacing with virtually all PLC platforms currently in use, without requiring separate hardware variants for different controller types. Additionally, the unit features a dedicated Teach-in input (pin 2, white/WH conductor) for rapid threshold calibration in the field without the need for specialized tools or software.
With a switching frequency of 10 kHz and a response time of ≤ 50 µs, the GLL170T-B333 is engineered for high-throughput applications such as presence inspection on high-speed conveyors, electronic component counting, or thin-material detection in printing and packaging lines.

Frequently Asked Questions – GLL170T-B333 SICK Fiber Optic Sensor
Q1: What is the price of the GLL170T-B333 fiber optic sensor?
A: Pricing for the GLL170T-B333 depends on order quantity and delivery requirements. Contact AUMI via hotline 0917 991 589 to receive a competitive quotation along with expert guidance on selecting compatible fiber-optic cables for your specific application.
Q2: Does the GLL170T-B333 support PNP or NPN output?
A: The GLL170T-B333 supports both – PNP and NPN – selectable by the user through the on-device configuration menu. This eliminates the need to stock separate hardware variants for different PLC types, significantly reducing spare parts inventory.
Q3: Does the GLL170T-B333 require a separate fiber-optic cable?
A: Yes. The GLL170T-B333 is a fiber-optic amplifier and must be paired with a compatible fiber-optic cable to form a complete sensing system. SICK offers a comprehensive range of compatible cables within the GLL170 product family. Contact AUMI for guidance on selecting the appropriate cable type for your application.
Q4: What does the IP66 rating mean for the GLL170T-B333?
A: IP66 indicates the device is fully dust-tight (first digit: 6) and protected against powerful water jets from any direction (second digit: 6). This allows the unit to be cleaned with high-pressure water, making it suitable for food & beverage, pharmaceutical, and other demanding industrial environments.
Q5: How is the detection threshold configured on the GLL170T-B333?
A: The device features a dedicated Teach-in input on pin 2 (white/WH conductor). The operator positions the target object within the sensing field and activates the Teach-in function – the amplifier then automatically learns and stores the optimal switching threshold without requiring any external tools or software.
Q6: Where can I purchase genuine GLL170T-B333 SICK fiber optic sensors?
