SENSOBAR^ K-F

nnnn

PRESSURE SWITCH

nnnn

GENERAL CHARACTERISTICS

nnnn

The K - F pressure switches series are diaphragm or piston sensing

nnnn

element type, depending on the pressure working range.

nnnn

K4 series is equipped with NO or NC electrical contact, the F4 series

nnnn

has SPDT contact arrangement.

nnnn

The set point is adjustable by means a screw on the top of the switch

nnnn

head. Dedicated mechanical holders protect the electrical contact from

nnnn

casual pressure overload. The electrical connection is faston type and

nnnn

rubber cup or DIN plug protection are available.

nnnn

These pressure switches are used in oleodynamic and pneumatic appli-

nnnn

cation, on machine tools, pumps, etc. as safety device.

nnnn

Pressure range from 0,05 to 400 bar.

nnnn

Easy adjustment.

nnnn

Simple installation.
