C7035A1080 Honeywell Minipeeper UV Flame Sensor

C7035A1080 Datasheet

The Honeywell C7035A1080 Flame Sensor 0-250F W/600F 6 FOOT LEAD WIRES.

Overview

The Honeywell C7035A1080 is a compact UV (ultraviolet) flame sensor, often called a “Minipeeper,” designed for flame detection in burners and combustion control systems. It detects the ultraviolet radiation emitted by a flame and provides flame supervision to burner control logic. Its rugged design, integral mounting collar, and thermal ratings make it well suited for many industrial and commercial heating applications.

Specifications

Features & Benefits

• Compact, rugged UV flame sensor for reliable flame supervision

• Integral collar mounts directly on a 1″ sight pipe, simplifying installation

• Seals to 5 psi when properly installed, preserving safe combustion chamber integrity

• Rated for 0 °F to 250 °F ambient operation

• Wires in parallel with another sensor for difficult sighting setups

• Rugged design with 600 °F rated leads ensures durability in harsh environments

• Meets rain-tight and enclosure protection requirements

Applications

• Boilers, furnaces, and burner systems using UV flame monitoring

• Safety systems for gas, oil, or dual-fuel burners

• Retrofit or upgrade of existing flame detector installations

• Installations where space is limited or environmental protection is needed

Installation & Maintenance Notes

• Mount on a straight section of sight pipe, aligned with flame view

• Use black-iron or carbon steel pipe for the sighting section to minimize reflection interference

• Keep sensor wiring separate from ignition leads to avoid electrical interference

• Inspect and clean the sensor window periodically to maintain sensitivity

• Replace the UV sensing tube or the detector if flame detection becomes unreliable
