Terminal mold types (epoxy-sealed terminal type) also available.
FEATURES
1. Long life
High efficiency coil spring switching
mechanism for long life: More than 10
7
mechanical operations.
2. Great mechanical strength while
being compact and lightweight
The attachment pitch is 25.4mm
(1.000inch),
same as for the Z basic
model microswitch. Also, the outer cover
cap uses a strong plastic with excellent
mechanical characteristics. An M4 bolt
can be used for the attachment.
3. The overtravel (O.T.) is large with
great shock absorption
4. The switch itself is constructed to
be dust-proof and oil resistant
The switch itself is closed flush with the
diaphragm and the compressed rubber
ring, so that the terminal mold type
(epoxy-sealed terminal type) is perfectly
flush with the terminal parts.
TYPICAL APPLICATIONS
Used in sequence control of food pro-
cessing machines, automatic packaging
machines, conveyers, and processors.
Ideal for light industry machinery when
installation pace is limited and a protec-
tive construction is sought.
