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.

Reset: GND short
Reset: GND short
Normally operation: Open (internal pull-ups present)
*In abnormal conditions such as incorrect detection distance occurring due to lightning strike interference for example, resetting the input should recover normal operation
Precautions during Use
Interference from nearby metallic objects
When there are metal objects near to the sensor’s detection distance, to avoid malfunctions, use the sensor while maintaining distance from the metal objects specified as follows.
*When there are both fixed and movable metal objects, the separation distance used between the sensor and the object should be the one for the object nearest to the sensor. By positioning so that a fixed metal object placed at least at the distance value shown in figure (i), any interference caused by other movable metal objects further away can be eliminated.

Other
- When two or more sensors are used, separate them at 180 mm centers to avoid mutual interference.
- An abrupt temperature change such as blowing with heated air can cause malfunctions. Ensure correct operation.
- Remove any coins from the detection surface before power ON or resetting inputs.
- For approximately 2 seconds from the power ON or input reset, the surrounding environment is checked. During this period, any coins on the detection surface can affect the correct detection distance.Normally,removing any coins left on the detection surface and waiting for 2 seconds can recover normal operation.If the detection distance is not correctly obtained, however, 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. The tightening torque for the casing should be 0.5 Nm or less. The screws can be oriented either up or down. Washers up to 10 mm diameter can be used on the detection side, up to 8 mm diameter on the opposite side can be used.
- 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. Ensure correct operation.
- For other precautions during use, refer to the General Precautions for proximity sensors.
Reference 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.
