AHF2
SMALL, HIGHLY RELIABLE
TIP SENSOR CONTAINING
A PHOTO SENSOR
AHF2 (TIP)
SWITCHES
Compliance with RoHS Directive
FEATURES
⢠Realizes miniaturization of equipment
and spaces saving. Size of body:
9.5Ã9.5Ã9.3 mm
⢠The contact type is equivalent to
normally closed contacts, which satisï¬es
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
proï¬les 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
