LA8N Series Digital Counters
Product Overview
The SenSource LA8N is a simple, self-powered count-up device with a prominent front reset button. Panel-mounted and affordable, it is available with either a non-voltage input or a universal voltage input. The non-voltage model counter handles 1,000 parts per second and the universal voltage handles 20 counts per second. We recommend this counter for use with our CR Series Capacitive Proximity sensors and many other compatible sensors.
