• With exterior diaphragm
• Plunger spacing 12 or 16 mm
• Upright housing according to DIN 43697
• Degree of protection IP67 according to IEC 60529

Exterior diaphragmThe exterior diaphragm protects the plunger guide against the entry of very fine dust (dust from grinding, casting, glass, etc.) and prevents the plunger seizing. At the same time, plunger sticking, caused by resinous lubricating coolants, can be prevented with this exterior diaphragm version. Switching elements
