Sensor boxes SRBC
Key features and product range overview
Function
Sensor boxes SRBC are used for electrical feedback and control of the position
of process valves actuated using pneumatic quarter turn actuators. They can be
mounted quickly and easily on quarter turn actuators with a hole pattern to
Innovative Flexible Design
Pre-assembled mounting adapter
for ease of installation
The trip cams can be set easily
without additional tools
Sturdy, corrosion-resistant design,
ideal for use in harsh operating
conditions
Clearly visible 3D position indicator
allows rapid detection of the
current position of the quarter turn
actuator
Weather-tight housing for outdoor
applications too
Mechanical, inductive or magnetic
switch variants for virtually all
ranges of application
Intrinsically safe variants for use in
potentially explosive areas
Two cable inputs for common power
supply for the sensor box and
solenoid valve as standard
VDI/VDE 3845 using mounting adapters. The sturdy design of the sensor box
SRBC is ideal for the harsh conditions in process automation.
Sturdy aluminium housing with two
cable inputs M20x1.5
Captive stainless steel screws on
the housing cover
Pre-assembled stainless steel
mounting adapter 80x30 H20 for
ease of mounting on standard
drives as per VDI/VDE 3845
