Proximity Switch Certified for INMETRO Ex d/db/tb IIC / IIIC T4 / T6 Rated for use in Gas & Dust Zone 1, 2, 21 and 22
This Proximity Switch has a 316L Stainless Steel Field Wireable Connection Head - Back Entry housing with SPCO / SPDT (Form C) , 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.
Using the latest production methods and materials this product meets global certification requirements and its robust design makes it suitable for use in arduous and hazardous environments. Euroswitch products are also available with multi-approvals including combinations of the following global and regional certification standards;
ATEX / IECEx Ex d (Ex db); Ex ia; UL & CSA Cl I Div 1 & 2 and Cl2 Div 1 & 2; TR CU; INMETRO; KCs; FM; JIS; PESO; CCC; and NEPSI.
The ES series proximity switches meet the requirements of IEC 61508:2010 Routes 1H & 1S with Systematic Capability (SC3) as an element/subsystem, and are suitable for use in safety-related systems performing safety functions up to and including SIL 2 with HFT=0 (1oo1) and SIL 3 with HFT =1 (1oo2).
