(i)Caution

  • Regarding RoHS compliance: The products are RoHS non-compliant only when alteration BMC is selected. The products are RoHS-compliant when BMC is not selected. As some parts used in the alteration are RoHS non-compliant, the RoHS notation on this page has been changed to non-compliant. "Non-compliant" is also indicated in the certificate due to information on the left. Since there are no changes to the product, please contact us if you need a Certificate of RoHS Compliance for a part number that does not have alteration BMC selected.
  • Please note that the swaged flange options, NFC, RFC, and LFC, are not reflected in the CAD data.
