Quadrature Sensor with Target and 0.009 Inch
$1,300.00
This item appears to be some sort of quadrature position sensing device, most likely used with a laser collimation system. The main housing, of heavy stainless steel, carries two labels. The first is a Keufel and Esser label with a part number ’71 2627′, and the second is a Cubic Precision final inspection sticker.
The main sleeve diameter is 2.250 inches, and the sleeve is 1 inch in length. The sleeve is stepped down to a diameter of 1.500 inches, and the step has black lacquer with four quadrant lines, three in white, and one in red. On the face of the stepped piece is a cover with a target circle 0.375 inches in diameter. The cover, when removed, reveals the active quadrature detector segments, each of which is bisected by one of the quadrant lines on the step. There is a cable from the rear of the housing with a special polarized nine-pin plug. We do not have the readout unit.
The second item furnished with the detector is a calibration plate in a sleeve mount that slides over the inner step. It has a red dot on it which I assume is supposed to be aligned with the red index mark. The cell for the plate is engraved ‘CALIBRATION .009 IN’. The glass plate is held at an angle within the cell and offsets the incident beam by exactly .009 inches in the direction of the red dot.
We have no way to test the detector, but there is no reason to believe it is not fully functional. The overall condition appears to be near perfect. There aren’t even any score marks on the main sleeve.
