LC309-KB-A Cleanroom Flush-Mount Phone (SIP / Analog / 4G)
Hygienic Voice Communication for Cleanrooms and Pharmaceutical Facilities | SIP · Analog · 4G | IP65 (NEMA 4 equivalent) · IK10 · CE · FCC · RoHS · ISO 9001 | 2-Year Warranty
The LC309-KB-A Cleanroom Flush-Mount Phone is an industrial communication terminal engineered specifically for cleanrooms and pharmaceutical production areas where sanitation protocols, chemical resistance, and flush integration are mandatory project requirements.
This device is designed to be cleaned daily, mounted without gaps, and specified directly in cleanroom drawings without additional engineering assumptions.
Cleanroom Suitability (Key Decision Factors)
ISO Cleanroom Applicability
Suitable for ISO Class 5 to ISO Class 9 environments
Gapless front surface minimizes particle retention
Flush-mount design supports validated cleaning procedures
Note: Device suitability refers to material choice and surface design. Room classification remains the responsibility of facility design and airflow management.
The LC309-KB-A ensures:
Safe, hygienic, and reliable communication without compromising cleanroom integrity.
Hygiene & Gapless Design
Fully sealed PET membrane overlay covering keypad and display
No individual mechanical buttons, no gaps, no recesses
Buttons and LCD located beneath a single continuous membrane
Flat front surface prevents bacterial growth and particle accumulation
Designed for frequent wipe-down and disinfecting cycles
This construction eliminates common contamination points found in conventional industrial keypads.
Chemical Resistance (Procurement-Critical)
Front surface and keypad materials are resistant to:
Isopropyl Alcohol (IPA, ≤70%)
Hydrogen Peroxide (H₂O₂, vapor or liquid, ≤26%, ≤40 °C, intermittent exposure)
Chlorine-based cleaning agents (typical cleanroom concentrations)
Material notes (transparent disclosure):
PET membrane offers strong resistance to alcohols and controlled peroxide exposure
Prolonged high-temperature, high-concentration, or UV-assisted peroxide exposure may reduce service life
Cleaning concentration, temperature, and cycle frequency directly affect lifespan
