Product Description

Product Description

LH/LHA 24 Series Intelligent defrosting vehicle separator
Under the severe weather such as frost,snow,rain,fog,the penetrating power of the light curtain is reduced then the defrosting function operates automatically , In normal working condition (no frost,snow,rain and fog), the heating system stay non-launching to prolong the working life of the system.
 
Features

• With Intelligent heating function,Defrost function starts automatically under severe weather to eliminate the block to light path from frost,snow,rain and fog;
• Aspheric surface optical lens totally eliminate spherical aberration,aberration and stray light;
• Build-in self-diagnostic function,detection output function and alarm output function;
• Light penetrability power(Receiving light intensity of receiver),directive function, easy for on-site installation and maintenances;
• RS485series communication meet customers' different task requirement by initial setting and meanwhile acquire on formation on  every light beam and system working status;
• Reliable separation for vehicles, the reliability is high to 99.9% under fine whether and not less than 99.5% even under rain snow or fog whether.

Max sensing Distance	18m
Space between optical axis	24mm
Min sensing object	Common scan:38mm; Cross scan:24mm
Protection Function	Instant over voltage protection. Reverse polarity protection
Output	Detection output,alarm output and self-diagnostic functions The size of trigger is selectable(common factory setting is 120mm trigger, and the distinguish ability is basis on the min sensing object)
Output type	On-off output,   current<150Ma(30V DC),   NPN,PNP optional
Series output	RS485 series connector,baud rate19200,half-duplex asynchronous communication; 1 start-bit,8 date bits,1 stop bit,no parity bit
