Carlo Gavazzi introduces infrared photo switches

Carlo Gavazzi product story

Nov 27, 2008
Carlo Gavazzi has introduced heavy-duty infrared (IR) photo switches designed specifically for door and entrance applications.
The IRPHS60 and IRPHS20 switches offer ranges of up to 60m indoors and up to 15m or 40m for outdoor installations (20m for IRPHS20).
The transmitter incorporates a double-emitter GaAs diode, which provides a 950nm IR beam modulated at 1.33kHz.
Wall-mounted in the same axis as the transmitter, the receiver module has an LED sensor and horizontal adjustment facility, enabling quick alignment to provide a reliable infrared barrier.
Full 90deg horizontal adjustment is provided by a rotation support with screw block, ensuring flexible installation for up-and-over doors, sliding gates and sectional doors.
The switches can also be used for security applications and torque screws are optionally available to prevent external intrusion.
Switching is via a NO/NC changeover relay rated 1A at 24V AC (resistive load).
The photo switch can be supplied by AC or DC, 12/24V power, and consumes 110mA at 24V AC (transmitter and receiver).
Both transmitter and receiver units are housed in aluminium enclosures 60 x 130 x 52mm in size, protected to IP66 against dust and moisture ingress, and operate over the extended -20 to +60C temperature range.
Sturdy and shock-resistant construction makes them equally suited to industrial, commercial or residential installations, including houses, apartment blocks, offices and retail stores.
These switches carry all relevant IEC and EN approvals, together with CE marking and certified RoHS compliant.
