1.5TH SMR Adapter

Click for larger image

The 1.5TH Series magnetic adapters provide an SMR nest which mounts in holes having a diameter of 1/8" - 5/8" or 4mm to 15mm.  Shank diameters are held to close tolerances (−0.0001" to −0.0005") for precision slip fits.  The adapter holds the centerpoint of a 1.5" diameter SMR 1.000" (or 25mm) above the surface of the part and on centerline of the shank to a tolerance of ±0.0005" (0.013mm).  The SMR seats on a 3-point conical land and is held in place by a magnet.  An optical alley allows the SMR to be rotated down for a lower shooting angle.  Construct the desired part number using the information below, or make up your own - we don't have room to show all possible sizes!
