L25 SINGLE-BEAM PHOTOELECTRIC SAFETY SWITCHES
Product description
The L25 and L26 product families from
SICK represent a new generation of
single-beam photoelectric safety switch
for type 2 applications, which, in combi-
nation with an external test device, fa-
cilitate operations and make processes
safer and more ecient. Thanks to the
innovative BluePilot operating concept
with feedback LED, the alignment of
sender and receiver is easier than ever.
Smart Sensor diagnostic functions
provide insight into the status each indi-
vidual sensor at all times, thus creating
the basis for successful and ecient
communication. Thanks to the ultra
robust VISTAL
®
housing and predictive
maintenance, L25 and L26 are extreme-
ly reliable and prevent unscheduled
machine downtime.

1)
The test input may not not be operated when not connected. The test input has a pull-up resistor to activate the sender (sender on) even when not connected.
Therefore, an active-switched LOW signal is required to activate the cyclic test with test gap (sender o).
2)
Digital output for controlling the downstream test device, not an OSSD according to IEC 61496-1. Short-circuit protected output.

SICK L25, L26 are single-beam, photoelectric safety switches for type 2 applications. The device has a blue pilot optical alignment system for easy setup and alignment. It can be used in conjunction with an external test device for operations and processes to be safer. The ultra robust VISTAL housing protects the switch from extreme environmental conditions. The device has protection class 3 with supply voltage of 24V DC, residual ripple of ≤5V, and power consumption of ≤30 mA.
