SICK 1218660 Retro-Reflective Photoelectric Sensor | Buy from Henvi

For companies seeking maximum reliability, millimetric precision and extreme durability in their industrial automation systems, the SICK 1218660 Retro-Reflective Photoelectric Sensor (Model Reference: WLA16P-24162100A00) stands out as one of the market’s leading technological solutions.

Developed by the renowned German brand SICK, this retro-reflective sensor has been designed to meet the most demanding object detection challenges in production lines, packaging processes, conveyor systems and automated logistics flows.

With an adjustable sensing range of up to 10 metres, this device provides complete flexibility in industrial machinery layouts. Thanks to its coaxial optics (autocollimation technology), the sensor eliminates blind spots and can detect objects with absolute precision, even when positioned directly against the device or the reflector.

This model simplifies component compatibility within electrical panels through a flexible Push-Pull digital output (selectable PNP and NPN). This versatility optimises inventory management and significantly reduces the time required to integrate the sensor with different types of programmable logic controllers (PLCs).

The housing of this compact photoelectric sensor is manufactured from VISTAL®, a patented glass-fibre-reinforced plastic material exclusive to SICK. This innovation provides mechanical strength superior to aluminium, making the device resistant to heavy impacts, constant mechanical vibrations and aggressive cleaning chemicals (ECOLAB Certified).

The visible red light beam with PinPoint LED technology projects a focused and sharp light spot, enabling fast and intuitive alignment in the field. In addition, integrated IO-Link connectivity allows real-time diagnostics monitoring, intelligent parameterisation and predictive maintenance strategies to prevent unexpected production downtime.
