Compact 3-button counter with LCD display, NPN/PNP inputs, and selectable memory Key benefits Space-saving design: small footprint fits tight control panels and mounting locations without sacrificing visibility or usability. Simple, reliable operation: three-button interface provides fast setup and intuitive control—reduces operator training and input errors. Clear readings: built-in LCD delivers high-contrast, easy-to-read numeric displays for quick verification on the line. Wide compatibility: includes both NPN and PNP signal interfaces so the counter works with standard proximity, photoelectric, and other sensor types and integrates easily with PLCs and automation systems. Flexible data handling: switchable memory counting lets you choose whether counts are retained or cleared on power cycles; dedicated data erase function provides secure, on-demand reset of stored counts. Core functions Three-button user interface for start/stop, increment/decrement, and mode selection. LCD display for real-time count readout. Dual-signal compatibility: NPN and PNP input interfaces. Selectable memory counting and manual data erase. Practical applications Production line part counting: mount the compact counter near a conveyor with a photoelectric sensor to track item quantities and trigger batching or downstream processes. Assembly and packaging stations: use with proximity sensors to monitor assembly output, verify packaging counts, and simplify shift change handoff with retained or cleared counts as required. Machine integration and PLC systems: connect to either NPN or PNP sensors to feed reliable count data into an automation system for inventory tracking, quality checks, or event logging. Why choose this counter Designed for industrial use where space, compatibility, and straightforward operation matter. Keeps operators focused on production with a minimal, robust control set and a readable display. Provides flexible memory options so you can match behavior to workflow and record-keeping needs.
