Technical Data
The housing of this switch consists
of a single part bag housing which
is closed at its end by resin
(P8 housing type); this makes the
switch mould-proof. This mould-
proof switch may thus also be used
in "tough" environments subject
to the detrimental influences
of humidity or dirt. Alternative
housing types: unsealed version
(P5) or plate bar version (P1).
All housing types are voltage-free.
Due to its constructional size the P
switch is one of the most compact
thermostats available. This ensures
a very fast response rate.
Its rectangular homogenous con-
structional size provides excellent
thermal conduction characteristics.
The housing is resistant against
temperatures (permanent tem-
perature: 160°C), with a temporary
increase in temperature up to
200°C max. being permissible for
a short period only.
The standard version is equipped
with 100 mm long (length of
stripped isolation: 10 mm)
insulated leads or wire connection
(AWG 24).
Special leads or wire (larger diame-
ter to AWG 22) or different lengths
available on request.
