  • 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.

  Technical Data

  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

  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.

  Application
  

  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).
