M=BUS® Tool Set The M=BUS® system is customizable to a wide range of applications in the field of impact testing. To grow with the demands of more complex configurations the system wiring has to be extended. The M=BUS® Tool Box contains a set of essential utilities for an easy and quick system maintenance and for the creation of custom-made arrangements. It consists of useful tools for cable preparation and connector crimping and provides a starter set of Enviroflex® coax cables, connecters and adaptors.

1 Tools 1.1 Stripping Tool

The Stripping tool is used to dismantle and strip the Enviroflex® cable for assembling of M=BUS® cables. For this work special blade blocks have been designed. The blade block has to be chosen in accordance with the connector that should be crimped to the cable (refer to section 2 at page 4 and section 3 at page 5).

1.2 Crimping Tool

The crimping tool is used for squeezing the M=BUS® connector to a cable that was pre-pared with the help of the stripping tool. The stamping for .128“ (3,25 mm) and .028“ (0,71mm) of this tool has to be used in accordance with the assembling notes for the connector as described in section 2 on page 4 and section 3 on page 5.
