●接收头是一种特殊的红外接收电路，它将红外接收管与放大电路集成在一体，体积小（大小与一只中功率三极管相当），密封性好，灵敏度高，性价比高。它有三条管脚，分别是电源正极、电源负极以及信号输出端，其工作电压在5V左右，只要给它接上电源即是一个完整的红外接收放大器，使用十分方便。
●接收头的主要功能包括接收红外信号、放大、选频、解调几大部分，因为输入信号是已经被调制的信号，经过它的接收、放大和解调会在输出端直接输出原始的信号。从而使电路达到最简化！灵敏度和抗干扰性都非常好，可以说是一个接收红外信号的理想装置。
●红外接收头有多种称呼，中文叫接收头、红外线接收头、红外线接收头、接收器，遥控接收头等，英文全称为：Infrared Receiver Module，业界常将此简称为IRM或RCM.
