Terminal Blocks - Barrier Blocks play a primary role in electrical connections and distribution in a range of industries. The T38042-12-0 is a Barrier Block commonly used in the building, transportation, aerospace, and machine automation industries. This article provides an overview of the T38042-12-0’s application field and working principle.

Application Field

Barrier Blocks, including the T38042-12-0 model, are used in low power applications and are capable of withstanding up to 1,000V. This makes them ideal for carrying low-voltage wiring. For this reason, they are commonly used in industries that require precise voltage regulation and in places where there is an elevated risk of voltage shock. For example, in the Construction Industry, they are great for schlep connections and wire routing. In the Transportation Industry, they are used to connect switches, control units and warning devices. In the Aerospace Industry, they are used for distributing signals from flight control systems and instruments. Finally, in the Machine Automation Industry, they are used for linking various parts of circuit regulators, automation sensors and controllers, with signal transmission accuracy.

Working Principle

The T38042-12-0 Barrier Block consists of two parts. The body, which serves as the base, has two pairs of plated walls that support the plastic or metal parts. The plastic or metal parts are secured into the base of the body with two opposing screws. When the screws are locked, they form an electricity resistant barrier and provide insulation for the wires inside.  The wire is then inserted between the plastic or metal parts and is connected to the substrate or the electric circuit board. A wire also runs from the plastic or metal parts to the barrier wall, which serves as an insulation layer. Finally, a jumper is attached to the barrier wall and connected to the barrier wall and the substrate to complete the circuit.

Conclusion

The T38042-12-0 Barrier Block is a cost-effective and reliable solution for the needs of multiple industries. Its application field includes the building, transportation, aerospace, and machine automation industries. Moreover, its working principle involves a two-piece body, two opposing and locked screws, and a jumper attached to the barrier wall. In conclusion, the T38042-12-0 Barrier Block is an ideal choice for low-voltage wiring and connections.
