Sigma safety terminals
Safety terminals made from self-extinguishing Polyamide-6, with matt black base,
MS-58
brass terminal (DIN 17660), tempered, zinc-plated and dichromated steel
ring, and cover made from orange-coloured self-extinguishing polypropylene.
● Anti-shearing: the connection is made by means of a tightening mechanism, which
distributes the pressure across the entire contact surface, avoiding friction and
occasional stress that can damage the conductors.
● Unloosenable: the ring that surrounds the brass body guarantees that the
pressure exerted by the actual conductors cannot open the terminal and loosen
the connection.
● Full insulation: all the SIGMA "S" terminals are supplied with a terminal-covering
cap, avoiding any accidental contact with live parts.
All the gauges can be coupled together, forming strips of any length. Operating
voltage: 500 V.
