490-85 

CLF / LCD Friendly Micro Link IR Receiver 

 

 

DESCRIPTION 

The 490-85 is a CFL (compact fluorescent light) / LCD (liquid crystal display) version of the 490 Micro 
Link series IR receivers. It is specifically designed to have greater immunity to high frequency 
ballasted CFL and overhead fluorescent type infrared inference and to have exceptional IR reception 
range.  
 
These small IR receivers have been designed primarily for mounting in panels, doors, cabinets, etc. 
for control of A/V equipment behind closed doors. They may be mounted in walls, ceilings, wall 
speakers, etc. - anywhere an inconspicuous appearance is desired. Their high sensitivity allows 
placement behind speaker grilles and still receiver IR commands up to 20 feet away.  
 

FEATURES AND SPECIFICATIONS 

ƒ

  IR carrier frequency reception bandwidth: 30 to 60 kHz. 

ƒ

  IR carrier adjustment: 32 to 56 kHz (allows output carrier frequency to be matched to a 

controlled component for optimum performance). 

ƒ

  IR reception range: > 50 feet 

ƒ

  Dimensions: 2.75” Length  x 0.75” DIA. Bezel is 0.90” DIA. 

ƒ

  Works in normal 3-wire mode (12VDC, IR, GND). 

ƒ

  Red talkback LED for system verification. 

ƒ

  RF Grid included for EMI interference reduction. 

ƒ

  Includes 3-Terminal Block for easy extension of 7 foot ribbon cable. 

ƒ

  7 units may be powered by one 781RG power supply.  

ƒ

  Normal Operating Power: +12VDC, 20mA. 

Note

: The 490-85 will not operate in 2-wire Phantom Power mode.  

 
INSTALLATION 

This unit is meant to be interfaced to Xantech Connecting Blocks, such as CB12, 789-44, 791-44, etc. 
 

MOUNTING 

1.  Drill a 3/4” hole in any flat surface, such as a cabinet panel. Pass the cable and body of the 

490-85 through the hole and secure from the rear with the nut (supplied).
