Installation and Usage Precautions
Use within the specified temperature range (-30 to +105). Avoid excessive heat which can degrade product performance. When soldering, do not melt solder in the resin head to prevent wire breakage, short circuits, or insulation damage. Do not touch the resin head directly with a soldering iron. When dividing or bending lead wires, maintain a distance of at least 10mm from the resin head and ensure a bending radius greater than 1mm. Avoid applying excessive force to the lead wires. Handle the ceramic element with care to prevent cracking or chipping. Evaluate product quality before resin molding. Provide appropriate fail-safe functions in your product to prevent secondary damages from abnormal operation or failure.
