YJJ XT-FPCB FPC Gasket Seal Cushion Pad for Portable Gas Detector Replacement Accessory

Features:

Product Overview

Model: XT-FPCB

Category: Special sealing buffer gasket for gas sensors and FPC wiring, suitable for multiple electrochemical and catalytic combustion gas probes, used for waterproofing and dustproofing of sensor bases, buffering and shock absorption, isolating gas leakage, and separating FPC flexible boards. It belongs to the internal consumable accessories of the detector.

I. Material Parameters

Base Material: High-density, aged-resistant silicone rubber / Black foam silicone rubber

Optional Materials: EPDM (triple rubber), anti-static foam

Surface Characteristics: Dust-free, low volatility, does not corrode FPC flexible circuits, resistant to electrochemical sensor electrolyte corrosion

II. Physical Specifications

Regular Thickness: 0.5mm / 1.0mm (Support custom thickness 0.3 - 2mm)

Structure: Middle opening, ring-shaped gasket style, opening fits the outer diameter of the sensor probe

Tolerance: Shape ±0.1mm, Inner hole tolerance -0.05 to +0.1mm

Hardness: 35 - 45 Shore-A, soft and compressible, uniform under pressure

III. Environmental and Weather Resistance Performance

Operating Temperature: -30℃ ~ +80℃

Storage Temperature: -40℃ ~ +100℃

Resistant Environments: Moisture-proof, dust-proof, resistant to weak acids and weak alkalis, resistant to sensor electrolyte leakage erosion

Compression Recovery: After compression by 30%, the recovery performance is stable, and long-term compression does not cause permanent deformation

Service Life: 2 - 3 years in normal industrial environment

IV. Functions, Compatibility and Application Scenarios Core function

The sensor probe housing is sealed with the main unit housing to prevent external moisture and dust from entering the gas chamber.

It provides buffering and shock absorption to prevent damage to the FPCB flexible wiring and sensor components due to assembly compression.

It isolates the sensor gas path to prevent gas leakage and ensure detection accuracy.
