Safety Switches

SICK has unveiled its next-generation L25 and L26 family of single-beam photoelectric safety switches, equipped with SICK’s “BluePilot” alignment and IO-Link for smart, real-time communication, ensuring maximum machine uptime while protecting personnel from hazardous machinery.

With a long scanning range up to 50 metres, the SICK L25 and L26 are Type 2 devices available in visible red light and infra-red (IR) versions for wide versatility in safety applications up to PL c (SIL 1).  The IR and red-light versions could also be used together to avoid the potential for signal interference and introduce redundancy for applications requiring a higher level of safety.

Rugged and robust, the SICK L25 and L26 single-beam safety sensors are ideal for collision- or access protection of barriers, gates, doors or racking systems, including over multiple access points at longer scanning distances.  With the ability to cascade up to four pairs of sensors, the versatile L25 and L26 can also be combined to achieve effective perimeter guarding of machines, or access protection to robot cells or machine-tending areas, including the option to use instead of a light curtain in space-limited machine designs.

The SICK L25 has a scanning range up to 20m, and the L26 up to 50 metres. Both use SICK’s PinPoint LED technology to achieve an accurate, intense, eye-safe light-spot which makes set-up and commissioning of the sensor straightforward.  With added guidance SICK’s BluePilot on-sensor alignment, sensors and reflectors can be set up quickly and precisely and time-consuming adjustments are avoided.
