The mechanical durability of ZB5AS944 is up to impressive 300000 cycles.
The ZB5AS944 provides the following standards:
?IP69 (rated as ’’high-pressure cleaning’’)
?IP67 (rated as "dust tight" and protected against immersion)
?IP66 (rated as "dust tight" and protected against heavy seas or powerful jets of water)
?IP69K (rated as ’’complete assurance ’’provides the highest protection rating on the scale)
The resistance to high pressure washer is at 55 °C, distance: 0.1 m.
The NEMA rating for this item is 4X, which means it is a subset of the NEMA 4 rating (protected against dust), but must provide additional protection against corrosion. Only enclosures fabricated from corrosion-resistant material, such as stainless steel and aluminium, can qualify for the NEMA 4X rating.
This item is classified as ’’ Green Premium Product ’’, which provides the following:
?Environmental information about the unit
?Minimal use of hazardous substances in, and beyond, compliance with regulations (RoHS, REACh)
?A promise of sustainable and environmentally friendly performance
?Product Environmental Profiles (PEPs) for easy carbon footprint calculation
?End-of-life instructions for reduced cost and optimised recycling
The cumulative tolerance must not exceed 0.3 mm / 0.012 in.: T1 + T2 = 0.3 mm max.
Frequently asked questions & answers
What is the different between a push button switch for an emergency stop and a general-purpose push button switch?
A general-purpose push button switch is used for controls, e.g. to start machine operation or simply to switch modes. An emergency stop push button switch however, is mainly used as a safety measure to stop hazardous events.
