The cable entry threads are 20mm, ½” or ¾” NPT female.
The EX-6120, 6165 S ERIES IR enclosure is manufactured from die cast aluminum*. Therefore, the use of glands,
conduit fittings and blanks made from brass should be avoided because if moisture is present, bi-metallic corrosion may
occur due to the chemical reaction between the two materials.
Glands and fittings plated with nickel, tin or zinc will provide improved protection but in harsh environments the use of
stainless steel is recommended.
