ButterflyMX Small Controller Enclosure - Fact Sheet

Product Data Sheet

The ButterflyMX Small Controller Enclosure gives installers a standardized, professional way to deploy ButterflyMX access control at gates, garages, guard shacks, detached buildings, and other small or remote entrances. By combining enclosure, mounting, power, and wiring organization into one solution, it reduces custom design work, installation time, missing components, wiring errors, and future service calls while delivering a cleaner, more secure installation.

Designed for one to four doors, the NEMA-rated enclosure includes a backplane, an integrated 12VDC or 24VDC, 4A power supply/charger (factory set to 12VDC) and a four-output PTC- or glass-fuse-protected power distribution module. It accommodates up to two ButterflyMX 2-Door Controllers, or one 2-Door Controller and one ButterflyMX Cellular Router, with an organized layout that simplifies mounting, field wiring, cable management, and service access.
