JDM6-51M Electromagnetic Preset Counter (Carry Type) is a mechanically-driven industrial counting device designed for precise numerical control in automation systems. Featuring an all-metal enclosure and enhanced electromagnetic coil mechanism, it reliably processes pulse signals to execute preset carry-over operations.

Equipped with six-digit mechanical display wheels, the device supports cyclic counting from 0 to 999,999. The top-mounted rotary knob allows quick preset value adjustment. Upon reaching the predefined threshold, the integrated contact mechanism automatically generates carry-over signals while resetting the counter for the next cycle. Specially developed anti-jitter circuitry effectively filters signal interference, maintaining counting precision. Silver alloy contacts ensure reliable switching with contact resistance ≤50mΩ, compatible with AC 220V/3A or DC 24V/5A loads.

This product finds application in yarn winding control for textile machinery, quantitative packaging systems, and press machine operation monitoring. The modular design facilitates easy installation via panel mounting or DIN rail attachment. Operating reliably within -20℃ to +70℃ temperature range, its protective construction resists dust and oil mist exposure. With 2 million mechanical cycle certification, it delivers durable performance in demanding industrial environments.
