TXM-433
UHF Radio Telemetry Transmit Module
The TXM-433-5 and TXM-433-10 integrate
a low power FM UHF radio transmitter on
a small module. Together with the matching
RX2-433-14 or RX2-433-40 receiver a one-
way radio data link can be achieved over a
distance up to 200 metres on open ground.
TXM-433-10 transmitter (back & front view)
Typical features include:
CE Certified by independent Notified Body
Verified to comply with harmonised radio standard ETSI EN 300 220-3 and EMC
standard ETSI EN 301 489-3 by accredited Test Laboratory
PCB Mounting, space saving SIL style
SAW controlled wide band FM transmission
High data rates, 5kbps and 10kbps versions
Analogue or Digital data input
Wide supply range 2.7V-4.0 or 6.0V-9.0V @ <17mA
The transmitter modules are most commonly employed in Wireless Security systems. The transmitter
and the matching receiver (RX2) are approved to harmonised radio standard ETSI EN 300 220-3 and
EMC standard ETSI EN 301 489-3. The TXM and RX2 modules 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 their small size and low power
requirements, both modules are ideal for use in portable, battery-powered applications such as hand-
held terminals.
Typical applications include :-
Domestic and commercial security
Guard patrol / lone worker protection
Medical Alert / Nurse Call systems
Mobile panic attack
Computer networking
Remote industrial process monitoring
Data transfer through hazardous environments
Lighting control, Garage door openers
Fire alarms
Picture / antique protection alarms
