Document no. REV 1.0 Date 10/25/2007
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
