Description
OMRON H7EC‑BL
Technical Specifications: Counting digit 6‑digit mechanical decimal wheel; input signal trigger mode voltage‑free contact input; maximum counting speed 10Hz; no external power‑supply required; count value memory retention permanent without battery; operating temperature ‑10‑55°C; storage temperature ‑25‑70°C; humidity 10‑90%RH without condensation; screw‑terminal wiring; panel‑mount structure; weight approx 75g.
Functional Features: Self‑powered mechanical counting principle without external power source; 6‑digit mechanical digit‑wheel directly shows accumulated total value; permanent memory of count data without battery backup; voltage‑free contact trigger input compatible with proximity‑sensor and limit‑switch outputs; compact panel‑mount size; manual reset button clears total count value.
Application Scenarios: Production‑equipment output‑quantity accumulation counting; mechanical‑equipment cycle‑operation‑times statistics; packaging‑machine product‑count recording; legacy‑equipment counter spare‑part replacement; workshop equipment runtime‑related pulse‑count statistics.
Performance Parameters: Mechanical counting mechanism delivers stable long‑term accumulation performance; count data will not be lost due to power‑failure events; mechanical digit‑wheel readout remains clear in workshop ambient‑light conditions.
Material Composition: Black flame‑retardant plastic housing; internal precision mechanical gear‑digit‑wheel assembly; metal contact trigger mechanism; brass nickel‑plated screw‑type terminals; manual reset mechanical push‑button component.
Structural Features: Compact rectangular panel‑mount housing; front‑face 6‑digit mechanical digit‑wheel display window; manual reset button on front panel; rear‑side screw terminals for trigger‑signal wiring; mounting clips for cabinet‑panel installation.
Working Principle: Each valid contact‑closure trigger pulse drives internal precision mechanical gear set, advancing mechanical digit‑wheel by one digit. Count value accumulates mechanically through gear transmission. No electric power is required for maintaining digit‑wheel position. Pressing front‑panel reset button drives gear‑set return‑to‑zero mechanism and clears all digits back to zero state.
Installation Requirements: Install unit into standard cabinet‑panel cut‑out and lock mounting clips; connect trigger‑signal contact‑wires to rear‑side screw terminals; keep trigger‑signal wire away from high‑power‑cable interference sources; mounting position avoids continuous mechanical vibration exceeding allowable specification.
Usage Notes: Trigger‑input signal must follow specified contact‑closure pulse‑width requirement; do not apply excessive force on manual reset button; avoid operating under condensation or corrosive‑gas conditions; do not exceed maximum 10 Hz counting input frequency.
