Description BXINDA3K Flameproof Limit Switch , BXIND is ideal for outdoor use or in adverse environments where a combination of explosion proof plus sealing requirements are needed. To comply with explosion-proof requirements the BXINDA3K Flameproof Limit Switch, BXIND has flame paths within the housing, which cool exploding gases below the ignition temperature before they reach explosive gases surrounding the housing. Flame paths on the BXIND are (1) an extended plunger between the switch cavity and head and (2) the cover housing threads on the front of the switch. These products are weather sealed for outdoor use and designed for explosive gas/dust environments. They may be interchanged with HDLS products by using an adapter plate. All heads are field adjustable at 90° increments. Side rotary BXIND products can be adjusted for clockwise and counterclockwise actuation. Honeywell explosion-proof switches are designed specifically for use in hazardous location applications. The BXIND enclosure is sealed for protection against corrosion, water, dust, and oil as defined in NEMA 1, 3, 4, 6, 7, 9 and 13 and IP67 as defined in IEC60529.
