Infrared radiation The NORMAL/LOW switch is
equipped.
Number of infrared radiating lamps
21/14 (at NORMAL position/at
LOW position)
Infrared emission strength
1.9 W or more (at peak and at
NORMAL position)
Infrared emission output
1.9 W or more (at peak and at
NORMAL position)
SX-2130 Infrared Receiver
Modulation system
Pulse position modulation system
Infrared receiving sensitivity
1mW/m
Number of channels
13
Frequency response
100 Hz to 5.5 kHz
Distortion
Less than 0.5 %
Signal-to-noise ratio
50 dB or more (Maximum)
The greater the distance between
the receiver and radiator is, the
worse the signal-to-noise ratio
becomes. At the limit of the
infrared emitting distance of the
infrared radiator, signal-to-noise
ratio is about
35 dB.
(See "Installation location of the
infrared radiator" on page 38.)
Maximum output 10 mW or more (25 ohms)
Battery
Rechargeable lithium ion battery
(3.6 V)
Operating time
