Proximity Switch Certified for INMETRO Ex ia IIC / IIIC T4 / T6 Rated for use in Gas & Dust Zones 0 and 20
This Proximity Switch has a 316L Stainless Steel Field Wireable Connection Head - Back Entry housing with NAMUR LFO (Normally Open) , volt free, hermetically sealed Rhodium (Tungsten optional) contacts. It has a maximum switching current of 2.5A .
It requires the use of a magnetic target to operate. This versatile switch provides highly reliable continuous monitoring across a wide operating temperature range.
From the extreme low temperatures of –60°C/-76°F found in Arctic, Russian and Alaskan oil fields to elevated temperatures of greater than 100°C found in power generation sites, this switch is proven to withstand it all.
Suitable for use in the design of safety functions up to SIL2 or SIL3.
