Product Detail

Product details

DL-R50A is a new designed receiver module. It has the function of high speed and high sensitivity, its bandwidth is adjustable. Narrow bandwidth has higher anti-interfere capability, so it can have longer distance, the sleeping function of the module itself can realize the special requirement of low power consumption.

◆ Application

A: low cost consumer electronics applications;
B: home and building automation;
C: remote fan controllers.
D: infrared transmitterr replacements.
E: industrial monitoring and controls.
F: remote lighting control.
G: wireless alarm and security system.
H: remote keyless entry(RKE).

◆ Notes for usage

01
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.
02
The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding magnetic ball, inductance, capacitance etc.)

03
When using with narrow bandwidth, it requires higher frequency stability of the transmitter module, it can get better result when working with our transmitter module.
