IRB-4X
- LED alignment indicator on the
receiver simplifies installation.
- Supervised relay output provides a
"detect" signal in case of power failure.
- Non-reflective through-beam system is
not affected by shiny surfaces.
- Modulated infrared beam is not
affected by sunlight, rain, dust or dirt.
- Wide transmission angle of 24 degrees
simplifies installation and increases the reliability of operation.
- Wide temperature operating range for
applications from cold storage to steamy food prep areas.

 APPLICATIONS:
The IRB-4X photocell is used as a
safety, reversing, or opening device in conjunction with automatic operators. The
IRB-4X will work with any control board that accepts dry contact in the output. This
easy to install reliable photocell is used with garage doors, rolling doors, parking
barriers and other equipment.
| HOW IT WORKS:
The IRB-4X transmitter and receiver
are mounted in line of sight at a distance of up to 75 feet. When the infrared beam
is broken the internal relay is de-energized and detection signal is produced on the relay
contacts. The red LED indicator on the receiver is lit when the IRB-4X receiver is
not aligned or when the beam is interrupted. |
 The IRB-4X works
without lenses so it is easy to align. Making it less sensitive to fog, dust, snow
& sunlight! |
EXTEND TIMER OPTION:
This operation is available in the
IRB-4X-T model. The delay is activated after the beam was broken and the detect
signal was issued by the internal relay. The delay extends the detect signal after
the beam is re-established, so in effect, the detect signal is extended beyond the
presence time of an obstruction between the IRB-4X receiver and transmitter. The
extend time is adjustable by a potentiometer in the range of 0 to 15 seconds. |
