Johnson Controls F262KDH-01C Airflow Switch

The Johnson Controls F262KDH-01C Airflow Switch is a heavy-duty SPDT snap-acting PENN switch designed for critical monitoring of air velocity within commercial ductwork. Engineered to detect the presence or absence of airflow, this unit is a vital interlock for make-up air systems, exhaust ventilation, and heating/cooling processes to prevent coil icing or equipment overheating. Supporting a wide voltage range of 24 Vac to 240 Vac and a maximum air velocity of 2000 FPM, the F262KDH-01C provides reliable performance in high-demand environments. This model serves as the official direct replacement for F62AA-8, F62AA-8C, and F62AA-9, ensuring a seamless field upgrade without extensive mounting modifications. The Type 3R (NEMA) polycarbonate enclosure is plenum-rated and dust-protected, making it suitable for indoor industrial applications. Each unit includes two stainless steel paddles (2-1/8" x 6-7/8" and 3-1/8" x 6-7/8") to accommodate different duct sizes and flow requirements. An accessible range adjustment screw allows technicians to calibrate the trip point accurately during commissioning.

• Direct HVAC Cross-Reference: Specifically designed to replace legacy Johnson Controls F62 series models including F62AA-8C and F62AA-9.
• Plenum-Rated Protection: The NEMA 3R enclosure meets NEC requirements for installation in environmental air spaces and provides superior dust resistance for the internal PENN switch mechanism.
• Versatile Media Compatibility: Capable of managing max duct temperatures up to 176°F, making it ideal for high-temperature exhaust and heat recovery systems.
• Simplified Field Wiring: Features a large wiring space and color-coded terminals to reduce installation time and prevent wiring errors in the field.
• Adjustable Sensitivity: The integrated range adjusting screw allows for fine-tuning the airflow station response based on specific system static pressure and velocity.

What is the maximum air velocity this switch can handle?
The F262KDH-01C is rated for a maximum air velocity of 2000 FPM. Operating above this limit may cause mechanical fatigue to the stainless steel paddle.

Can this airflow switch be mounted in a vertical duct?
Yes, it can be mounted on the top, side, or bottom of a duct. If vertical duct mounting is required with downward flow, the field adjustment screw must be recalibrated to compensate for the weight of the paddle.

Is this switch suitable for outdoor use?
While the Type 3R enclosure offers excellent dust and moisture protection for indoor and plenum environments, it is not designed for direct exposure to outdoor weather conditions without additional shielding.
