Flexible application options, fast installation, absence of dead zones and shock resistance of 50g mean that PSENopt II are ideal for use in a rugged everyday industrial environment – even in extreme cold (up to -25°C) or dusty production environments. As well as the first Type 3 safety light curtains, which are suitable specifically for applications up to PL d, you also have Type 4 versions. With their 5-pin connector, they can be connected directly to the decentralised modules PDP67. There are no limits to the physical arrangement of the safety light curtains: thanks to coding, you can even position the light curtain sensors physically close to one another.
