ELM 4-1.130 is a type of LED spacer, standoff or header which is used to maintain consistent distances between multiple stacked PCB boards when connected. This type of spacer is designed for a tight fit between the PCB boards and can be used to prevent misalignment or over-tightening of screws.

The ELM 4-1.130 is a 4-pin M4 hex spacer and comes in a variety of lengths. It has an overall length of 8.3mm, a width of 6.3mm and an inner diameter of 4mm for PCB board mounting. The spacer also has an integrated clamping hole for mounting the PCB boards together.

ELM 4-1.130 is designed for increased performance, reliability and flexibility. It has a high degree of accuracy and is abrasion resistant. It also has a special contact surface which ensures reliable electrical connections. The spacer is also made of polyacetal, a durable and rigid plastic material.

The working principle of ELM 4-1.130 is simple. It uses the principle of electrostatic shielding which is based on the Coulomb law. In this process, the electrical flow between two objects is limited by creating a thin layer of non-conductive material between them. This thin layer shields the objects from each other and ensures accurate connections.

ELM 4-1.130 is used in a wide range of applications such as small appliances, computers, test instruments and audio systems. The spacer can be used to maintain consistent distances between multiple stacked PCB boards when connected. It is also used in light-emitting diode (LED) lighting fixtures to ensure uniform lighting and stop the light from shining in unwanted directions.

ELM 4-1.130 is an ideal spacer for high-density mounting of multiple PCB boards. It provides a precise and reliable electrical contact between two layers and ensures secure assembly. The spacer also offers superior shock and vibration resistance and corrosion resistance. This makes it an ideal solution for high-end electrical and electronic applications.
