Ideal for monitoring door opening or movement past a point. Uses a matched pair of transmitter/ receiver transducers operating at 40KHz to reliably detect movement 3 - 7 metres away. Circuit is crystal locked for maximum efficiency.
Transducers are mounted on a separate PCB for remote mounting.
Adjustable trigger sensitivity. Auto Reset (after ~ 0.3 Sec) or Latched On output options. An LED lights when the circuit is triggered.
A 12Vdc output pulse is available to drive small DC loads (up to 50mA) like a buzzer, siren, relay (e.g. Order Code 1168), opto-coupler (e.g. MOC3021),etc. Designed for indoor use.Specifications
