Information

Attachment mounting clamps GN 478 are primarily designed for mounting sensor holders GN 479 and retaining plates GN 479.1. They are fitted with a central thread and, with d₁ = B15 bore and higher, an additional bore template 4 x M4.

In the standard version the clamping screw is a socket cap screw with hexagonal socket DIN 912. It can be replaced by a clamping kit GN 511 (article code see table of dimensions).
