Product Detail
1.Contact type: reed / magnet contact 2.Max. airflow velocity :50m/s 3.Approvals VDE + UL File No. E250507

The airflow monitor (NC/NO) is designed to indicate the loss of air movement of a fan or filter fan. The contact detects the loss of air movement caused by fan failure or blocked filter media regardless of direction of air. Its simple mechanical operation makes it a viable alternative to electronic monitoring systems.

Technical Data:

Contact type reed / magnet contact Normally closed (NC) switch contact open when air is flowing Normally open (NO) switch contact closed when air is flowing Max. switching voltage NC: 240VDC (UL), 240V AC/DC (VDE) / NO: 60VDC Max. switching current NC: DC 500mA / NO: DC 170mA Max. switching capacity 10W (resistive load) Switching threshold of airflow velocity > 2.5m/s (hysteresis: > 1m/s) Max. airflow velocity 50m/s Contact resistance < 370mOhm (with wire) Max. air humidity 70% RH (not precipitating) Service life > 100 000 cycles Connection 2 x single strand AWG 28, length 500mm, tip of stranded wire 5mm stripped and tinned (NC: black, NO: blue) Mounting alternatively integrated in protective grille (see table), mounting clamp or mounting clip Casing plastic according to UL94-HB, black Fitting position bidirectional tab perpendicular to airflow Operating/Storage temperature -20 to +50°C (-4 to +122°F) / -20 to +80°C (-4 to +176°F) Protection type IP20 Approvals VDE + UL File No. E250507 Note The product of switching voltage and switching current must not exceed 10W. The max. voltage and max. current must not be exceeded, not even short-term (voltage/current peaks). The resulting voltage and current peaks of inductive or capacitive loads must be restricted by a contact protection circuit.
