It is typically used in automotive and industrial electronics applications. Here, we take a look at the construction, application fields and working principle of such terminal blocks.

Construction and Features

The 1505-Y Barrier Blocks feature a thermoplastic body with flammability rating 94 V-2. Its clamping connections have cable entries from 0.5 to 2.5 mm² and rated voltage up to 600V. It can be used with a wide range of connecting methods, including screw, spring or cage or dovetail terminals. The electrical contact is made of phosphor bronze with gold plating. The mounting holes are in conformity with DIN standard and can be easily mounted on an electrical enclosure using a screwdriver.

Application fields

The 1505-Y Barrier Blocks can be used in a variety of applications, especially in automotive and industrial electronics. Examples include protection circuits, lighting systems, power supplies, fans, digital input and output modules, battery chargers, industrial robots, automotive electrical control systems and electronic control units.

Working Principle

When installing the 1505-Y Barrier Blocks, the user needs to connect the power lines to the block. Next, the user needs to attach the housings, securing the cable blocks with screws. After that, the cable blocks need to be connected to the various connections. This is done by using screws and wire lugs. Once the cables are securely connected, the user needs to ensure that the cables are safely insulated. This is done by using insulation sleeves. The electrical contact between the cable blocks and the connections is ensured using screw or spring terminals. This ensures reliable electrical contact without having to solder the connections.

The 1505-Y Barrier Blocks are highly reliable and are ideal for use in the automotive and industrial electronics industries. The electrical connections are reliable and the insulation sleeves ensure that the cables remain safely insulated. The convenient mounting holes make it easy to fit the block into an electrical enclosure. Overall, the 1505-Y Barrier Blocks are an excellent choice for reliable electrical connections.
