Non-ferromagnetic Target
The list below includes recommendations for ways in which you may be able to switch to a non-ferromagnetic target.
- Use a non-ferromagnetic stainless steel, such as 1.4571,
- Use alloys, such as AlZnMgCu1,5 (3.4365); consider the lower mechanical tensile strength,
- Apply non-ferromagnetic coats that are about 1 mm thick to the original target,
Apply bronze by laser welding,
Electroplate with copper and subsequently gold plate because of oxidation,
Shrink non-ferromagnetic metals in combination with gluing.
Proposed materials

Change from SGS4311 to SGS4701
Tips and notes for a successful change between the model series.
SGS4311
SGS4701
With a size of 4.5 x 10 x 12 mm, the
sensors are compatible in terms of their
construction.
The sensors for the SGS4701 controller can-
not be exchanged. Sensor, sensor cable and
controller are matched to each other.
When the sensor, the cable or the controller
are defect, a replacement system is required.
