Photo IC diode assemblies
S10108, S10109
For flame eye, using photo IC diode
instead of CdS cell
The S10108 and S10109 sensors are designed specifically for flame detection (flame eye) in oil-fired hot water boilers and
heaters. These sensors incorporate a photo IC diode instead of CdS cells and are available with 2 types of incident light
direction (head-on type S10108: and side-on type: S10109). Each sensor is assembled in an easy-to-install package along
with the cable.
Features
Spectral response suitable for detecting oil burner
Easy-to-install assembly with cable
Little variation in output current and good linearity
(in comparison with conventional types using
phototransistors and CdS cells)
Applications
Flame detection in oil boilers and heaters
Safety devices and alarms for heat generating devices
Photorelay control devices

Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the
product within the absolute maximum ratings.
