Industrial proximity sensor

The SICK GLL170T-B432 is a rectangular fiber-optic sensor designed for industrial automation tasks that require precise object detection. It operates on a 10 V DC to 30 V DC supply and draws 40 mA during normal operation. The unit offers selectable PNP or NPN switching outputs with a maximum load current of 100 mA. A 2 metre four-wire cable provides the electrical connection.

Thermal and acoustic profile

As a solid-state optical device with no moving parts, the sensor generates negligible audible noise and minimal heat during standard use. Power consumption remains low at 40 mA across the permitted supply voltage range. The visible red LED light source operates at a 632 nm wavelength. These characteristics support stable performance in typical control cabinet or machine mounting environments.

Sustained load behaviour

The sensor supports switching frequencies of 2 kHz and 10 kHz, selectable via menu, with response times of 250 µs and 50 µs respectively. Programmable time delays up to 9,999 ms allow adaptation to process timing requirements. Sensing ranges reach 350 mm in proximity mode and 1,100 mm in through-beam mode under defined conditions. The 4-digit display provides continuous status feedback during extended operation.

Questions about this item

How do I mount the GLL170T-B432 and wire the 2 m cable so the teach-in input works?

Mount the 10 mm × 31.7 mm × 72.5 mm rectangular housing with two M3 screws, then connect the 4-wire cable: brown to 10–30 V DC, blue to 0 V, black to the switching output (PNP or NPN selectable via menu), and white to the teach-in input for remote programming.

What part will need replacement first on the GLL170T-B432?

The visible red LED (632 nm) is the only consumable component; its output degrades over years of continuous operation, so plan to replace the entire sensor when the sensing range drops below the 350 mm proximity or 1,100 mm through-beam specifications.

At what point does the GLL170T-B432 overheat or miss counts during continuous running?

The sensor handles sustained use until the 100 mA output current limit is reached; exceeding it triggers short-circuit protection and stops switching, so keep the load below 100 mA to avoid the first hard limit.
