Product overview A compact, portable sensor tester for checking two, three or fourwire DC sensors with PNP or NPN outputs. Designed to verify inductive (metal induction), capacitive, optoelectronic, magnetic and ultrasonic sensors quickly and reliably, helping avoid unnecessary replacements and enabling onsite fault finding. Key benefits Fast verification: Confirms sensor operation in seconds so faulty parts are identified before replacement. Versatile compatibility: Works with a wide range of sensor types and wiring configurations, reducing the need for multiple tools. Portable and simple: Lightweight plastic housing and battery operation make field testing and bench checks easy. Improves troubleshooting: Adds a practical diagnostic step to reduce downtime and speed repairs. Features Compatible outputs: Supports PNP and NPN output sensors. Wiring support: Tests two, three and fourwire DC sensors. Sensor types: Suitable for inductive, capacitive, optoelectronic, magnetic and ultrasonic sensors. Power: Uses 2 x 6F22 9V batteries. Available in two versions: Type B includes batteries, Type A ships without batteries. Construction: Black plastic housing for durability and low weight. Size: 93x60x23 mm for easy carrying and pocket storage. Practical use scenarios Maintenance checks on production lines: Quickly verify proximity and inductive sensors on conveyors during routine inspections to reduce unplanned stops. Field commissioning and setup: Test optoelectronic and fiber amplifier sensors on site before final wiring and mounting. Troubleshooting machinery: Isolate sensor faults on magnetic and ultrasonic detection systems to confirm whether the sensor or wiring is at fault.
