2. Clean the bare metal with a degreasing agent,
Loctite ® 7063™.
3. Remove any excess degreasing agent and allow to
dry.
4. Apply a thin film of Loctite ® F246™ adhesive to the
flat metal surface of the sensor, ensuring the
adhesive is spread evenly over the entire surface.
Note: Follow all adhesive manufacturer’s
recommendations including storage life.
5. Fit the sensor, ensuring the lead exits in the corner
direction. Secure with two new bolts - Socket HD
Capscrew M10x35x1.5, Grade 12.9.
