RKI Explosion Proof M2A-XL Transmitter w/J-Box, UL 65-264_XL

The RKI Explosion Proof UL version M2A-XL Transmitter with j-box provides an alternate housing, which is slightly taller, wider and deeper, but the mounting holes, electronics and operation are the same as the original M2A housing. The slightly larger enclosure has more room inside for additional wiring. Since this housing is deeper than the original M2A, longer standoffs are required inside to properly bring the display up to the transmitter's window. Choice of LEL, H2 specific LEL, IR CH4, or IR Hydrocarbons transmitter.

Please call Customer Service at 800-829-9580 if you have questions in choosing the correct product.

The M2A sensor/transmitters can can operate as an independent, stand-alone monitor or connect to virtually any controller, PLC, or DCS and are designed to work with the RKI Beacon 110, Beacon 200, Beacon 410, or Beacon 800 Controllers.

Applications: Petrochemical plants, Refineries, Water & wastewater treatment plants, Pulp & paper mills, Manufacturing facilities, Automotive, Semiconductor plants, Chemical plants
