LC103-KB Heavy-Duty Industrial Telephone (Analog / SIP / 4G), yellow
Critical Voice Communication | Analog · SIP · 4G | CE, FCC, RoHS, IK10, IP67, NEMA 4X, ISO9001 standards | 2-Year Warranty
The LC103-KB is a heavy-duty industrial telephone designed for reliable voice communication in harsh industrial and infrastructure environments.
It delivers clear audio in high-noise areas and supports Analog, SIP/VoIP, and 4G (choose at checkout) communication within a unified, industrial-grade platform.
Designed for steel plants, manufacturing facilities, transport infrastructure, and outdoor installations, the LC103-KB withstands dust, moisture, vibration, impact, and extreme temperatures.
The die-cast aluminum enclosure, IP67 (NEMA 4X equivalent) protection, and IK10 impact resistance ensure long service life with minimal maintenance. Constructed from die-cast aluminum with a polyurethane finish, it is purpose-built to survive salt-air corrosion, physical impact, and extreme weather. Standardization is simplified through a consistent mechanical form factor across all network protocols.
Multiple communication options and consistent mechanical design make the LC103-KB easy to specify, deploy, and standardize across large-scale industrial projects.
