Carlo Gavazzi Sensor Tester

Carlo Gavazzi type ST-03 sensor testers are the fastest way to verify the main function on your sensor. The tester can be used for Namur, 2- wire DC, 3-wire DC and 4- wire DC. The sensor type (NPN or PNP) and output status NO (normally open) and (normally closed) is shown on the correspondent LED. The ST sensor tester has a buzzer to inform if the output is active, the tester can also check fault functions such as wrong sensor (e.g. AC sensors), defect sensor, incorrect wiring and fuse faults.
