Count metallic objects as they touch or pass within 0.059" of this counter's built-in sensor. It has an output relay to send a signal to another device when a set point is reached. The signal can start/stop a process or trigger an alarm. A scaling function lets you adjust the unit of measure to suit your application. Counter and enclosure are protected from dust and washdowns and can be used outdoors (rated NEMA 4X). Drill through the back of the enclosure to mount to a wall or work surface.
