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.
