描述 Description

MICRO SWITCH BX Series Hazardous Location Limit Switches (Non Plug-in),top pin plunger (momentary), 1NC 1NO SPDT snap action, 0.5 in - 14NPT conduit.The MICRO SWITCH BX enclosure is sealed for protection against corrosion, water, dust and oil as defined in NEMA 1, 3, 4, 6, and 13 and IP67 as defined in IEC 529. These enclosures also meet the European Hazardous Locations Designation: II 2 GD, Ex d IIC T6 Gb; 1 Ex d IIC T6 Gb; II 2 D Ex tb IIIC t85C Db. The entire series BX complies with the European Directive on Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres (94/9/EC) commonly referred to as the ATEX Directive. Compliance with the Essential Health and Safety Requirements has been assured by compliance with EN50014 1997 and EN50018 1994. MICRO SWITCH BX with conduit types 1/2-14NPT, 3/4-14NPT also meet the North American Hazardous Locations Designation: Class I, Groups B, C and D; Class II, Groups E, F and G and comply with UL Standard: UL 894, CSA Standard: C22.2 No. 25-1966, C22.2 No. 30-M1986. The MICRO SWITCH BX 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 BX 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 BX are
an extended plunger between the switch cavity and head and (2) the cover-housing threads on the front of the switch.
