General characteristics<br />
The LOVATO ELECTRIC limit switches have been<br />
designed to satisfy requirements for quick installation,<br />
wiring ease, simple setup, modularity, sturdiness and<br />
reliability.<br />
The body cover is hinged at the bottom and removable.<br />
The innovative locking bayonet mechanism provides for<br />
easy removal and repositioning of the operating head in<br />
the required configuration without tools. The heads have<br />
axial rotation of 45° angles.<br />
The auxiliary contact blocks are removable assuring<br />
wiring simplicity. The heads are made of metal while the<br />
body housing of self-extinguishing polymer<br />
thermoplastic for the KB types or of<br />
aluminum-zinc alloy (zama) for the KM types.<br />
