LEADS.;Minipeeper Ultraviolet Flame Detector, Used for Coal, Gas and Oil Fired Burners, 288 Inch Lead Length, -40/215 Degree Ambient Temperature, Mounts on 1/2 Inch Sighting Pipe Using A Integral Collar, Includes 1/2 Inch NPT Spud Connector

Overview

The Honeywell C7027A1064 is a Minipeeper ultraviolet (UV) flame sensor used in burner control systems. It senses the UV emissions from a flame to confirm presence, and is suited for installation in tight locations thanks to its compact design and standard ½-inch mounting. It often includes a 24 V LED status indicator for visual confirmation of flame status.

Specifications

Features & Benefits

• Compact and rugged “Minipeeper” form factor allows installation in constrained spaces

• LED indicator provides visual feedback of flame status

• Parallel wiring capability supports enhanced flame path coverage

• Sealed design for up to 5 psi when installed correctly

• Reliable UV detection with honeywell-grade construction

• Standard ½-inch collar simplifies mounting to sight tube

Applications

• Boilers, furnaces, and burner systems requiring UV flame sensing

• Installations with limited clearance or space constraints

• Retrofits where visibility or flame path is challenging

• Control systems needing LED flame status feedback

Installation & Maintenance Notes

• Mount sensor properly with clear sight path to the flame

• Use appropriate black iron sight tubing to avoid reflection interference

• Avoid running sensor leads in the same conduit as ignition wiring

• Periodically inspect and clean the sensor window

• Replace the sensor if UV response weakens or if LED status becomes erratic
