RKI Explosion Proof M2A-XL Transmitter w/J-Box, UL 65-264_XL
Description
The RKI Explosion Proof UL-listed M2A-XL Transmitter with junction box shares the same electronics and mounting pattern as the original M2A but provides a slightly larger enclosure with additional internal wiring room. Available in LEL general-purpose catalytic, H2-specific LEL, IR Methane (CH4), and IR Hydrocarbon configurations.

Frequently Asked Questions
What gases can the RKI M2A-XL Explosion Proof Transmitter detect?
The M2A-XL is available in four sensing technologies: LEL general-purpose catalytic (65-2640XL), H2-specific LEL (65-2641XL), IR Methane in both LEL and 100% volume ranges (65-2649XL-CH4 and 65-2658XL-CH4), and IR Hydrocarbons LEL (65-2649XL-HC). Select the configuration matched to your facility's primary combustible-gas hazard.
Can the M2A-XL operate without a controller?
Yes. The M2A-XL includes an OLED display, two fully programmable alarm relays, and a fail relay, enabling stand-alone operation with local alarming. It also integrates with
Beacon 110,
Beacon 200,
Beacon 410, or
Beacon 800 controllers or virtually any PLC or DCS via standard 4-20 mA and Modbus outputs.
How long do M2A-XL sensors last and how is calibration performed?
Catalytic LEL sensors last 2-3 years; H2-specific LEL sensors 3-5 years; IR sensors 5+ years. Calibration is non-intrusive via the built-in magnetic wand interface, eliminating the need to open the explosion-proof enclosure during routine maintenance.
What certifications does the M2A-XL carry?
The M2A-XL carries UL explosion-proof certification and features a patented water-repellent sensor cover. It is designed for petrochemical plants, refineries, water and wastewater treatment facilities, semiconductor plants, and other demanding industrial environments.
Does PK Safety service the RKI M2A-XL?
Yes. As an RKI Factory Authorized Service Center, PK Safety provides calibration, repair, and technical support for the M2A-XL. Call
800.829.9580 for parts, service scheduling, or application guidance.
