Product Overview 

 

The IRB-325 conforms to the UL325 standard when used with the powder coated steel 
hoods. Registration reference number 9901994.  The IRB-325 photocell is used as an 
external entrapment protection device type B1 non-contact sensor for use with automatic gate 
and door openers. 

 

The IRB-325 transmitter and receiver have a line of site range of up to 65 feet. The IRB-325 
operates on 12 VDC to 24 VAC and draw 150 mA maximum. 

 

The IRB-325 receiver is activated whenever anything interrupts the beam from the 
transmitter, triggering the relay output to change state and send a signal to the operator that 
there has been an interruption.
