Your advantages
Well-known connection principle allows worldwide use
Low temperature rise, thanks to maximum contact force
Satisfies the more stringent safety requirements of “Ex e” protection according to IEC 60079-7 for potentially explosive areas
Operation and conductor connection from one direction enable integration into front of device
Two solder pins reduce the mechanical strain on the soldering spots
The latching on the side enables various numbers of positions to be combined
