The Honeywell C7027A1031 Flame Sensor -40-215F
Overview
The Honeywell C7027A1031 is a “Minipeeper” ultraviolet flame sensor designed for flame supervision in combustion systems. It detects UV radiation emitted by a flame and is used in burner control and safety systems. With a compact form and ½-inch mounting, it is well suited for tight or constrained installations.

Features & Benefits
Compact “Minipeeper” design allows installation in tight spaces
UV flame detection works even under low-flame or intermittent flame conditions
Parallel wiring option helps extend flame coverage through multiple sight paths
Rugged construction ensures durability in combustion environments
Integral ½-inch collar simplifies mounting to sight pipes
Applications
Boiler and furnace flame monitoring
Burner systems where sight line or space is limited
Retrofit or replacement of older UV flame detectors
Systems requiring reliable flame detection with compact sensors
Installation & Maintenance Notes
Mount on a metallic sight pipe to maintain flame path integrity
Avoid locating sensor near high-voltage wiring during installation
Periodically inspect and clean the optical path to prevent signal degradation
If flame detection reliability degrades, replace sensor rather than attempt field repairs
