What type of component is this?
This is a threaded shaft coupling designed as a spare mechanical component for the Siemens SITRANS WS300 shaft-driven speed sensor.
What is the purpose of the threaded shaft coupling?
The coupling connects the SITRANS WS300 speed sensor to a rotating pulley shaft, allowing shaft rotation to be transferred accurately to the sensor.
Which equipment is this coupling intended for?
Siemens 7MH7723-1GH is intended for use with the SITRANS WS300 speed sensor, commonly installed alongside conveyor belt weighing systems.
Where is this component typically used?
It is typically used on conveyor installations where a SITRANS WS300 is mounted to a tail, bend or snub pulley shaft for belt-speed measurement.
What thread size does the coupling use?
The documented mounting arrangement shows M12 x 1.75 threaded connections. The mating shaft and installation dimensions should be checked before fitting.
How long is the coupling assembly?
The documented threaded coupling arrangement has an overall length of approximately 95 mm, with 25 mm end sections indicated in the mounting drawing.
Does the coupling use a set screw?
Yes. The mounting arrangement includes a set screw to help secure the coupling connection.
Is adhesive required during installation?
Siemens advises using a suitable thread-locking adhesive, such as Loctite, when installing the threaded shaft coupling.
Why is correct alignment important when fitting the coupling?
Correct alignment helps transfer pulley-shaft rotation consistently to the speed sensor and reduces unnecessary mechanical loading on the sensor bearings.
Can this coupling be used with any rotary sensor?
It should not be treated as a universal coupling. It is identified specifically as a spare component for the SITRANS WS300, so thread size, shaft arrangement and installation dimensions must match.
Does this component generate the speed signal?
No. The coupling is a mechanical connection component. The SITRANS WS300 sensor converts the transferred shaft rotation into the pulse signal used for belt-speed measurement.
What should be checked before replacing an existing coupling?
Confirm the speed sensor model, M12 x 1.75 thread compatibility, available installation space, shaft alignment and the condition of the mating threads and set-screw location.
