Modern design, maximum flexibility

A rectangular flameproof enclosure in low-copper die-cast aluminium (max 0.05%) offering the same fitting options as the modular series: micro switches, 2- or 3-wire V3 inductive sensors, NAMUR sensors or a 4-20 mA position transmitter. The low copper content increases aluminium's natural corrosion resistance, even in harsh environments.

It comes with two M20x1.5 entries as standard and is also available with four entries or NPT 1/2" threads. On top, a large yellow-and-black tower indicator is visible from every angle; removing it reveals a VDI/VDE 3845 interface (80x30 mm, 20 mm shaft) for mounting further components. The generous terminal compartment allows a solenoid valve to be connected through the box.
