Pepperl+Fuchs ST 03

The Pepperl+Fuchs ST 03 is a versatile sensor tester designed to easily check the switching status of various sensor types. Featuring two LEDs that indicate the switching state for both NPN and PNP configurations, this tester is well-suited for ultrasonic sensors thanks to its 100 mA output current. It supports a range of sensor wiring setups, including 2-, 3-, and 4-wire sensors, accommodating NPN, PNP, and NAMUR technologies. Distributed by BSP Automation, the ST 03 offers a straightforward and reliable solution for testing different sensor types in industrial automation settings.
