Controls – F792 Switchbox LP Series

The well proven design of the Keystone F792 Low

Profile Switchbox has been upgraded to simplify

switch setting, site wiring and weatherproof integrity.

Features

•Cams specially designed to operate

either V9 microswitches or

proximity sensors

•General purpose dustproof and

weatherproof enclosure to IP65

rating.

•Switches prewired to terminal strip.

•Cable entries: 2-off Pg 13.5.

•Suitable for direct mounting to

Keystone F790 actuators.

•Simple screw driver cam setting.

•Independently, top adjustable

cams, accessible at all degrees of

opening.

•Infinitely adjustable.

•Locking screw provides full face

friction of the cams ensuring

optimum repeatability, as cams

firmly lock after adjustment.

•Clearly visible position indicator.

•Anodised and ESPC* aluminium

enclosure provides full environmental

protection.

•Readily adaptable to suit all rotary

actuators.

•Terminal strip angled for easy

wiring.

* Electrostatic powder coating.

Options

•V9 microswitches.

•Inductive proximity sensors.

•Pneumatic switches.

•Direct mounted High Visibility

Indicator.

General Applications

For position sensing on manual or

automated valves in general industrial

environments.

Refer F792-K series Switchboxes for

hazardous applications.
