Questions & Answers (BP-series)

  • How should the switch be contacted with detected objects?

    Suitable for sliding / angled touch.

    When using for rotation indexing, adjust the position in consideration of eccentricity and core blurring accuracy of rotationg objects.
    According to the operationg circumstance, the signal point varies due to wear of the contacting part.
    Carefully calculate the angle and roughness of chamfer so that the contacting part is not easily worn off.
    Try not to bend the threaded part during installation. It will cause malfunction.

    [Within 5°]
    The degree required to turn on the switch
    when the detected object doesn't meet the switch end fully.

  • Please let me know the LED display type.

    LED display is placed on the cable which is 120mm distance from switch body.
    It will turn on when the switch is ON.

    Don't Connect directly to the DC24V power supply. LED can be damaged.

  • How can I wire Metrol switches when replacing cuttently using proximity sensors?

    For wiring, please refer to the following.

  • Are Metrol's cabtyre cables "Robot cables"?

    Metrol's Cabtyre cables are used as Robot cables without any safety compromise since the working voltage and current are low, though cabtyre cables are not applicable to UL, CSA, EN or other safety standards.
    However, Core-wire cables are not Robot cables.

  • Are CE-Mark Machine Directives / Low Voltage Directives applicable to Metrol products?

    Our products are applicable neither to CE-Mark Machine Directives nor to Low Voltage Directives.

  • Are Metrol products RoHS compliant?

    Our products comply with RoHS Directive and use lead-free solder.
