SICK WLL180T Series Fibre Optic Sensor, 0/20μm Detection Range, ABS/Polycarbonate Housing - WLL180T-P434


This Fibre optic sensor is a standalone photoelectric detector designed for Fibre-optic applications in industrial automation. It uses a visible red LED to monitor objects or through-beam arrangements and is suited to control tasks where compact, menu-adjustable detection and digital readout are required. The device connects via an M8 4-pin Interface and is supplied with a bracket for straightforward mounting.

Features & Benefits


• PNP switching output delivers simple integration with PLCs and actuators
• Selectable response times down to 16μs enable fast object detection
• Switching frequency up to 31.2kHz supports high-speed signalling
• Programmemable delays from 0ms to 9999ms allow precise timing control
• Dual 4-digit displays show setpoint and actual values simultaneously
• ABS/polycarbonate housing offers a Durable lightweight enclosure

**Applications**


• Suitable for high-speed counting on conveyor lines
• Ideal for proximity detection of reflective parts in assembly
• Used with through-beam fibres for long-range object sensing
• Can be used for presence verification in pick-and-place systems
• Suitable for integration where Compact bracket mounting is required

What supply voltage range does it accept?


It operates from 12V DC to 24V DC with typical current consumption around 50mA.

How is the sensing distance adjusted?


Thresholds and timing are set via the menu and a single teach-in button with numeric display feedback.

Which environmental temperatures can it withstand in operation?


It functions between −25°C to +55°C for normal ambient use.

What protection and connection details are provided?


The unit has an IP50 rating when fitted correctly, an M8 male 4-pin connector, and includes a steel mounting bracket.

How is the light source specified and what lifetime can be expected?


The sensor emits visible red light at 650nm from an LED with an average service life specified at 100,000 h at 25°C.
