MAG4R
The MAG4R is a strong and reliable magnet holder for AE-sensors with -R case: 29mm diameter (1.14inch) and 32 mm height (1.26 inch), e.g. the Vallen VS150-RIC (150kHz resonant AE-sensor with integrated preamplifier).

The two top handles help to remove the strong magnets (two times 200N) from the mounting surface. The material POM (polyoxymethylen) provides electrical isolation as well as high acoustic attenuation.

Size: 80*30*55mm, weight: 140 grams
Sensor load force: 30N, spring-load
Temp. Range: -10 to +90°C

MAG4M
Like MAG4R, but for sensors with -M case: D20*H14mm, holddown force 2x140N
Size: 70*25*50mm (incl. handles)

MAG4H
Like MAG4M, but for sensors with -H case: D20*H23mm
Size: 70*25*57mm (incl. handles)

MAG4V
Like MAG4M, but for sensors with -V case: D20*H38mm
Size: 70*25*72mm (incl. handles)

MAG2S
Two magnets with a hold-down force of 36N each are attached over a plastic-hinge at an aluminum frame. It provides a total hold-down force of approximately 144N. The sensor is pressed down by an adjustable screw via an elastic piece of rubber.

The hinges make the magnets fit to cylindrical surfaces with diameters down to 20cm. The MAG2S holder can attach sensors of sizes up to 31*31mm.

The total size is 85*45mm. The maximum temperature is approximately 65°C.
