ELM 5-140 is a type of LED spacer and standoff, which is designed for applications requiring mounting a printed circuit board (PCB) at a specific distance from a supporting surface. It is formed in an L-shape, providing a reliable support against lateral movement, such as tilting, vibration and shock. The ELM 5-140 also offers a secure locking system to ensure the PCB is firmly secured in place.

The construction of the ELM 5-140 involves two parts: an upper part, the spacer head, and a lower part, the standoff foot. The spacer head consists of a plastic or composite material with a wide diameter that securely holds the PCB against the supporting surface. The standoff foot consists of a smaller diameter tube and a locking nut, and is designed to prevent the upper part from moving or sliding away during operation.

The ELM 5-140 provides improved shock resistance and thermal insulation compared to traditional LED spacer and standoff systems. With a wide range of mounting options and an adjustable locking nut, the ELM 5-140 can easily be used for a variety of applications. Due to its ability to support heavy loads, the ELM 5-140 is suitable for use in applications that require high reliability and cost-effectiveness.

The working principle of the ELM 5-140 involves two key processes. The first process is the locking of the mounting bolt. This process involves inserting the mounting bolt into the pilot hole of the lower standoff foot and then hand-tightening the locking nut to a certain torque. This process will secure the standoff in place and provide support against lateral movement.

The second process is the connection of the circuit boards pre-fitted on the spacer head and standoff foot. This process involves connecting the signal wires from the PCB on the spacer head to the copper tracing on the standoff foot. This step is essential in order to ensure the electronic components on the PCB receive power. Once connected, the PCB assembly is now ready for use.

In summary, the ELM 5-140 is a reliable, efficient and cost-effective LED spacer and standoff system. Its unique L-shaped design provides improved safety and security, while its adjustable locking nut provides improved shock resistance and thermal insulation. Its ability to support heavy loads makes it suitable for a variety of applications. With its two-step process of mounting and wiring, the ELM 5-140 is easy to install and can be used in a wide variety of applications.
