LEMOS INTERNATIONAL CO. INC. releases the Lemos / Sena Industrial Bluetooth Headset

October 17th, 2017

The Lemos / Sena Tufftalk is the first fully Bluetooth integrated intercom device to both protect the user and supply a clearer communication channel. This device marks our continued commitment to the safety and efficiency of the industrial field.”

The Lemos / Sena Tufftalk,is an earmuff Bluetooth® communication and intercom headset, and is designed specifically to meet the communication and connectivity needs of industrial applications. Tufftalk sports a 1.4 km working Bluetooth range – the furthest of any product on the market today. Its sturdy design and tough manufacturing offers up to 15 hours of uninterrupted intercom communication between up to four headsets. Coupled with its seamless compatibility with other Bluetooth and two-way radio devices, including SENA SR10i which allows for wireless two-way radio communication, Tufftalk far outpaces the competition.

Breaking through the noise

In rough and loud environments, safety is key, and this is exactly where Tufftalk truly shines. Tufftalk’s secure earmuffs help protect users from harmful noise with an audio attenuation of 24dB. The ambient mode feature allows users to amplify external sounds – generating greater awareness of surroundings so important alarms or calls can be heard while still protecting hearing. For more active applications, Tufftalk offers an optional hard hat mount package.

“Poor worksite communication is costly for businesses,” Kim said. “With Tufftalk we applied Sena’s two decades of expertise to offer industrial strength seamless communication for the harshest of environments.”

Equipped with HD quality speakers, Tufftalk delivers crystal clear audio that industrial mobile workers need to stay safe on busy and noisy worksites. Tufftalk features Sena’s Advanced Noise-Control™ technology, which limits the interference of background noise while maintaining the full volume of voice communication.

Sena’s patented Jog Dial design is glove-friendly and easy to control, while the VOX technology allows users to answer phone calls, communicate and react to voice commands, all while hands-free. Tufftalk is also compatible with a Sena App to configure settings and presets easily through any smartphone. As with all Sena units, Tufftalk is completely firmware upgradeable to ensure it remains compatible with all of the latest Bluetooth technology.

PAT-HPA21G Ultra-Wideband Amplifier

February 10th, 2017

The Lemos PAT-HPA21G is high performance, low noise, ultra-wideband amplifier.
Based on GaN technology, the amplifier achieving high reliability and high efficiency. Most Most power amplifiers are divided into sub bands that cover:

  • 0.1-18GHz
  • 0.5-18Ghz
  • 2-18GHz
  • 6-18GHz

The Lemos Patriot amplifier is quite unique since it has both a relative good N.F but also a quite high output power P1db of 24dbm and high gain of 30db.
This unit can get even better specs if you don’t need the entire freq band of 0.8-21GHZ and only need for example only 6-18GHZ. It also has a  very small form-factor and light weight which makes it suitable for wide range of applications.

Features:

  • GaN Based
  • Ultra-Wideband Operation
  • Compact & Light Weight
  • MIL-STD 810F
  • Low Current 220mA Max.

Applications:

  • Driver Amplifier
  • Low Noise Amplifier in Receiving Chains
  • Radar
  • Ultra-Wideband Measurement Instruments
  • Lab Use
  • Telecomunication
  • Military
  • Medical

PW1-928 RF Data Transceiver Module

February 8th, 2017

The PW1-928 RF transceiver module is designed for reliable bi-directional transfer of digital data over distances of over 300 feet in cluttered urban environments (over half a mile in true line of sight). Operating in the 902 to 928MHz frequency band, the module generates a nominal +7dBm into a 50-ohm load and achieves an outstanding RX sensitivity of –112dBm.

The module uses the industry standard LoRa direct sequence chirp spreading protocol combined with a proprietary data structure to both simplify user implementation and to significantly improve packet transmission reliability. It has a Universal Asynchronous Receiver Transmitter (UART) serial interface that can be directly connected to typical microcontrollers, RS-232 converters or USB adaptors. The module automatically handles all radio functions resulting in a true UART-to-antenna wireless link. Configuration setup is also accessed through the UART interface.

Features

  • True “asynchronous UART to antenna” solution
  • Direct sequence (chirp) spread spectrum
  • 9.6kbps user payload data rate
  • Uses highly robust augmented LoRa protocol
  • Low power standby and TX-from-standby modes
  • Adjustable output power
  • User programmable address and channel-group
  • 3.3-volt logic I/O
  • Digital RSSI (read via serial port)
Applications

  • Direct RS-232/485 wire replacement
  • Asset tracking
  • Automated meter reading
  • Industrial/home automation
  • Wireless sensors
  • Remote data logging
  • Fleet management
  • Traffic and display signs
  • Mass-transit communications
  • Oil and gas sensing
  • Long-range data links
