Mitsubishi Electric Automotive U61001084 A2L Refrigerant Leak Detection Sensor Assembly

The Mitsubishi Electric U61001084 is an A2L refrigerant leak detection sensor assembly designed for use with compatible PEFY-NMSU series indoor air conditioning units. This critical safety component monitors for refrigerant leaks and triggers system alarms when refrigerant concentrations reach 4000 ppm.

Key Features:

• Factory-calibrated sensor designed specifically for A2L refrigerant detection
• Detection threshold set at 4000 ppm for reliable leak monitoring
• One-time use design - must be replaced if triggered
• Pre-calibrated from factory with no field calibration required
• Designed to last beyond the life of the equipment under normal conditions
• Integrates with compatible remote controllers to provide audible and visual alarms

This sensor assembly is located inside the fan coil unit and works in conjunction with PAR-42MAAUB or TAR-42MAAUB remote controllers to provide comprehensive refrigerant leak detection and alarm capabilities. When a leak is detected, the system displays error code 1521 and activates multiple alarm indicators to alert users of the potential hazard.
