transmitter module

Model No.: DL-T27A Description:wireless transmitter and receiver module Product Detail:DL-T27A transmitting module is designed to be thin and small size. It adopts SMD material on one side to make it thinner. There are three pins, similar to DL-T01A, but the display order is different. It is suitable to be use on wireless transmit system which require small size module.1. Application:a. Transmission for the signals from anti-theft alarm and various digital signal of low rate;b. Industrial remote control, remote measurement and remote sensing;c. Various remote controls for home-appliances and intelligent toys.2. Technical Specifications:Operating voltage: 3V 12V Operating current: max≤33mA (12V), min≤3mA (3V) Resonance mode: surface acoustic wave (SAW) Modulate mode: OOK/ASK Operating frequency: 315MHz-433.92MHz, customized frequency is available. Frequency error: ±150kHz(max) Transmission power: 25mW (315MHz at 12V) Rate: ≤10Kbps Encoding format: No Antenna length: 24cm (315MHz), 18cm (433.92MHz) 3. Size and Pin definition 4. Notes for usagea.Pls use soft lead wire or other hard metal (like telescopic antenna), the length should be chosen according to the respective frequency (24cm for 315MHz, 18cm for 433.92MHz). The antenna should be stretched as straight as possible if it is using soft lead wire.b. The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding magnetic ball, inductance, capacitance etc.)c. If applying the module inside the module housing, the antenna should be fetched out of housing. To connect the metal telescope aerial with 50ohm coaxial line will get better effect in transmission.d. Since the wireless frequency is precious natural resources, please do not keep the module always at transmission condition.
