- MCD-19_EN Download the CAD data (DXF / Parasolid / STEP / IGES)
Application
- Remaining change detection for POS, automatic vending machines, automatic ticket vending machines
- Remaining change detection for automatic payment machines at parking lots or highway tollgates
- Remaining tokens detection for token exchangers
- Remaining coins detection for ATMs
Features
- Detection distance of 19 mm for 1-yen coins (aluminum).
- Optimum for detecting all coin materials including aluminum, copper, and copper alloys.
- Not affected by residual dust in the coin receptacles.
- Metal fittings can be directly attached to the unit to adapt it to any mounting requirement.
- Thin profile means the unit can be mounted in a space as little as 14mm high, under the coin trays.
- A locking connector securely prevents disconnection of connectors caused by wire routing problems or vibration.
- The unit is equipped with a LED display for clear indication of operation status.
International Standards
- Our products do not have overseas safety regulations such as CE mark, UL standard, EN standard etc.
- Products is compliant to the RoHS directive.
* Please consult about "change of specification" and "request of specification" of the product.

*If a distance detection error occurs,due to lightning strike interference for example, perform input reset to restore normal operation.
Precautions During Use
Interference from Nearby Metallic Objects
When metallic objects are close to the detection field, to avoid malfunctions, position the sensor as follows.
When both fixed and movable metal obstructions are nearby, position the sensor at the distance of, or more than the nearest metal object. In the example on the left, the sensor is positioned at least 10mm from the fixed metal obstruction (see Fig.i) .This should eliminate interference caused by other metal objects further away.

Other
- When a number sensors are used, position them at 180 mm centers to avoid mutual interference.
-
An abrupt temperature change can cause malfunctions. Avoid actions that cause temperature change,such as blowing with heated air.
- Remove any coins from the detection surface before power ON or resetting inputs.
-
For approximately 2 seconds from power ON or input reset, coins on the detection surface can affect detectiondistance due to the initial surrounding environment check. Remove any coins, and wait for 2 seconds to recovernormal operation. If the problem persists, perform an input reset.
- Ferromagnetic materials such as ferrite near the sensor can cause malfunctions.
- LED turns ON when there is detection with or without output.
-
For mounting, use M3 screws. Always use plain washers to tighten the case and use a torque of 0.5 N·m max.The screws can be oriented either up or down.
- Washers to use: up to 10 mm dia. (detection side), Up to 8 mm dia. (opposite side)
- Any coin approaching at a very slow (reference speed: 3 mm/s or lower) cannot be detected.
- Mechanical stress on the detection surface can cause malfunctions.
- For other precautions, refer to “General Precautions” for inductive sensors.
Typical Values
Typical Values
With the centers of the coin and the detection surface aligned,move the coin
in a vertical direction toward the detection surface (referential surface) and
regard the position where the output switches ON as the detection distance.
