LC013 LCF013 AIRFLOW MONITOR
- Mechanical switch contact
- Versatile fields of application
- Small size
- Easy to connect
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. It’s simple mechanical operation makes it a viable alternative or electronic monitor systems.
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.
The LC013 is used as a signal contact to monitor fans or filter fans in stationary, self-contained protection Class I enclosures. It can be connected to monitoring systems with remote control or can directly to monitoring systems with remote control or can directly switch alarm devices, such as LED’ or signal lamps. Loads with capacities exceeding the indicated switching capacity must be switched via a relay, e.g. Our electronic relay SM010. The airflow monitor with NC contact closed upon loss of air movement, i.e. It indicates fan failure(e.g.) Red signal lamp). The NO contact closes when fan is in operation and serves as optical function display(e.g. green signal lamp).
