Mounting Studs Specifications

The document provides detailed specifications for various mounting studs used with accelerometers. Key parameters include thread types such as 1/4 UNF, 10/32 UNF, and M5, with dimensions approximately given in millimeters. The studs are primarily made from stainless steel 303 S31, with some variants incorporating epoxy resin for case isolation.

Material and Torque Settings

• Case material: Stainless steel 303 S31 or stainless steel 303 S31 combined with epoxy resin.
• Torque settings vary between 1.2 Nm and 1.8 Nm depending on the stud type.

Mounting Types and Isolation

• Non-insulated mounting studs are available for adhesive mounting.
• Case isolated studs provide electrical isolation between the accelerometer and the mounting surface, effectively eliminating earth loop problems.
• Use of epoxy on the flat face of the stud can enhance case isolation.

Temperature and Mechanical Limits

• Maximum operating temperature for case isolated studs is +200°C.
• Some studs are made from mild steel plated and nylon plastic coated, with a nominal force rating of 5.5 kg and weight around 15 grams.

Accessories and Variants

• SP/01 and SP/02 adapters are provided free with appropriate accelerometers.
• Case isolated mounting magnets (IM/01) are also mentioned as mounting options.

Dimensional Data

All dimensions are approximate and given in millimeters. Key dimensions include:

• Hex flats (A/F) typically around 9.5 mm to 21.3 mm depending on the stud.
• Lengths and diameters vary, with examples such as 12.2 mm length, 3.7 mm diameter, and 15.8 mm overall length.

Best Practices and Recommendations

• Careful application of epoxy resin on the flat face of the stud is recommended to ensure electrical isolation and prevent ground loops.
• Torque settings must be strictly followed to avoid damage and ensure proper mounting integrity.
• Selection between insulated and non-insulated studs should be based on the need to eliminate earth loops.
