receiver module

Model No.: DL-R12BF Description:wireless receiver module with code Product Detail:DL-R12BF is designed by adopting the best RF integrated circuit in the world. It has the technic of VCO and PLL, and the features of stable frequency, high sensitivity and high anti-interfere. As it has the decode IC, so it can be used directly. This module widely applies in wireless data transmission and wireless remote control. 1. Application:a.Wireless access control system;b.Various anti-theft systemc.Industrial remote control, remote measurement and remote sensing;d. Data transmit with low rate;e.Other wireless remote control.2. Technical Specifications:Operating voltage: 5.0V±0.5V Operating current: ≤2.5mA (5.0VDC) Operating principle: super heterodyne(VCO, PLL) Modulate mode: OOK/ASK Operating frequency: 315MHz, 433.92MHz, customized frequency is available Bandwidth: 1.5MHz (315MHz, test when the sensitivity decline to 3dBm) Sensitivity: better than -105dBm (50Ω) Rate: <9Kbps (at 315MHz at -95dBm) Decoding format: PT2272, AX5327 Output signal: TTL electric level, 4 route control output; output form with Latch and unlatch; Learning quantity: 20 remotes Antenna length: 24cm (315MHz), 18cm (433.92MHz) 3.Size and Pin definition4. Notes for usagea.Pls use soft lead wire or other hard metal (like telescopic antenna), It can not be either too long or too short, or it will affect the receiving distance. The antenna should be stretched as straight as possible if it is using soft lead wire, and as far as possible from the metal objects.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. There is short distance signal block up problem during the work of the ASK receiver module, pls pay attention to it during the operation.
