Datalogic Sensors
A Red LED Indicating the output status is visible on the
bottom side of the sensor. The versions with trimmer adjustment present also a green LED signalling the
switching stability according to the received signal's intensity. The rugged ABS housing always guarantees
IP67 protection. The S5 series offers a range of plastic tubular M18 photoelectric sensors.The most varied
optic functions can be chosen amongst the fixed focus 15 mm and 50 mm or

Leuze Sensors
Measuring Sensors can actively check distances,
position system parts and monitor other parameters in order to intelligently and independently initiate
actions and, e.g., intervene in processes for control purposes. Here, you will find a large selection of
technologies and designs for as efficient and faultfree system operation as possible. Our distance
sensors stand for maximum accuracy  over small as well as large distances.
