FEATURES
• Realizes miniaturization of equipment
and spaces saving. Size of body:
9.5
×9.5×9.3 mm
• The contact type is equivalent to
normally closed contacts, which satisfies
the PL Act.
• The internal sphere can be used over
an operation angle of 360 degrees in the
circumferential direction.
• There are three standard terminal
profiles which can be selected according
to the mounting direction of the PCB.
• The terminals are tin-plated for long-
term solderability.
TYPICAL
APPLICATIONS
• Gas heaters
• Electric fans
• Water vallet
• Infrared treatment device
• Electric pots with warming function
Compliance with RoHS Directive
CONTACT TYPE
Normally closed type (The photo transistor is ON when the
sensor is being used.)
APPLICABLE CIRCUIT
Refer to the dimensional diagram for the terminal Nos.
• VCC = 5 V
• R2 = 100 k
• Forward current,
IF, of the LED: 19 mA
(VCC = 5 V, R1 = 200
Ω)
• Forward voltage,
VF, of the LED: Typ = 1.2 V
BASIC CHARACTERISTICS
For Ta = 25
°C and applicable circuit conditions
1) Operation characteristics
(Operation speed 6 degrees/second)
• Operation angle (Output: VOL
→ VOH): 25 to 60 degrees
• Return angle (Output: VOH
→ VOL): Min. 20 degrees
2) Output (VO) characteristics (The sphere must be stationary.)
• VOL (photo transistor ON): Max. 1.0 V (horizontal)
• VOH (photo transistor OFF): Min. 4.0 V (inclined at an angle of at
least 60 degrees)
