This utility model discloses a MINI
infrared receiver head with a
metal shell and through-hole, comprising a shielding shell, a
receiver head body, and pins. The pins are connected to the
receiver head body, and the shielding shell is fitted onto the receiver head body. The shielding shell includes an upper shielding part, a lower shielding part, a front shielding part, a left shielding part, and a right shielding part. The receiver head body is installed within a cavity formed by the upper shielding part, lower shielding part, front shielding part, left shielding part, and right shielding part. The shielding shell is a
metal shielding shell. By adding a
metal shielding shell around the receiver head body and installing the receiver head body within the cavity formed by the upper shielding part, lower shielding part, front shielding part, left shielding part, and right shielding part, interference from
sunlight,
tungsten lamp light, energy-saving lamps, and fluorescent lamps on the
infrared receiving module
system can be reduced, improving the product's receiving sensitivity and receiving distance. Simultaneously, it can effectively shield high-frequency
electromagnetic interference, thereby improving the functionality of the
infrared receiver head.
