ButterflyMX Medium Controller Enclosure - Fact Sheet

Product Data Sheet

The ButterflyMX Controller Enclosure – Medium gives installers a standardized, professional solution for mid-sized multifamily, commercial, and multi-floor controller deployments. By consolidating enclosure, mounting, power, and wiring organization into one orderable system, it reduces custom design work, installation time, missing components, wiring errors, and future service calls while creating a cleaner, more secure, and easier-to-maintain installation.

Designed for five to ten doors, the enclosure includes a backplane, an integrated 12VDC, 10A power supply/charger, and an eight-output PTC- or glass-fuse-protected power distribution module. It accommodates up to five ButterflyMX 2-Door Controllers, with an organized layout that simplifies controller mounting, field wiring, cable management, power distribution, troubleshooting, and ongoing service access.
