TLA 346

In the line of TLA 346, Lelas developers have focused on improving the quality of communication and strengthening the design for use in extreme conditions. As a result, the company introduced an industrial intercom device with maximum protection against radio and electrical interference in a robust anti-vandal case.

Design Features

The cast shell of light aluminum alloy reliably protects the "stuffing" of the device from damage. The housing is hermetically sealed, with IP 66 protection, which completely eliminates dust and moisture penetration. On the central panel there is a 16-button keyboard with the ability to store up to 10 numbers in the device's memory. There is a tube with Teflon coating, but if necessary, you can use a loudspeaker in hands-free mode.


The industrial phone TLA 346 is designed for use in a dispatching system without a central switch
Easy dialing of the last dialed number using the BIS button.
Protection from radio interference, which provides clarity of communication in a noisy environment.
The connecting wire is made of stainless steel - can withstand weight up to 200 kg.


The shockproof phone is capable of withstanding vibrational loads and temperature fluctuations. It is used in any areas where reliable, high-quality communication is needed - railway lines, production facilities, extractive industries.
