TX2S-433-40-3V-SMD Transmitter

• UHF Narrowband FM Radio Transmitter
• Frequency: 433.920MHz
• Data Rate: 40kbps
• TX Power: 2.5mW
• Footprint: SMD
• Country: AUS/NZ
• Conforms to: Australian/New Zealand AS/NZS 4268:2003
• Radiocommunications (Low Interference Potential Devices) Class Licence 2000

Overview

• The TX2S module is a miniature PCB mounting UHF radio transmitter which enable the simple implementation of a data link at up to 40 kbps at distances up to 75 metres in-building and 300 metres open ground.

Features

• CE certified by independent Notified Body
• Verified to comply with harmonised radio standard EN 300 220-3 and EMC standard EN 301 489-3 by accredited Test Laboratory
• Data rates up to 40 kbps
• Usable range up to 300 m
• Versions available on 433.92MHz, 434.42MHz and 869.85 (TX3S)
• Small size: 20x10x2mm (without can), 20x10x2.6mm(with can)

Applications

Available for operation at 433.92MHz, 434.42MHz and 869.85MHz in Europe including the UK, both modules combine full internal filtering to ensure EMC compliance by minimising spurious radiations and susceptibilities. The TX2S/TX3S module will suit one-to-one and multi-node wireless links in applications including car and building security, EPOS and inventory tracking, remote industrial process monitoring and computer networking. Because of it’s small size and low power requirements, it is ideal for use in portable, battery-powered wireless devices such as remote control key fob.
