Terminal Blocks - Wire to Board are versatile interconnect devices suitable for the most demanding electronic connection requirements. One of the most popular products in this field is the OSTTA190161B terminal block. This product is usually installed as a unit, perfect for termination of electrical wires from a control board to other electronic components, like sensors or actuators. It has a patented design that allows for connection of high current up to 10A per contact. From motor control, data and wire termination, instrumentation, and communication applications, this terminal block offers convenient, secure, and reliable connections for all of your wiring needs.

OSTTA190161B terminal blocks are designed with a modular snap-in board mount configuration. The circuit connections are made by two non-locking screw terminals and multiple contact position combinations provide secure contacts for wiring. The high-power current contact is ensured by a silver-plated copper alloy insert. A special rubber pad design helps reduce wire fatigue and allows them to move freely, providing anti-vibration protection.

Besides the strength of its design, the OSTTA190161B terminal block also features a wide range of features, including an isolation distance of 28 ±2mm, and a temperature range of -55°C to 85°C. The terminal block supports the plugging and unplugging of wires multiple times, and it is waterproof and of course UL recognized. As for its size, it comes in two versions, one 180 mm and another 270 mm in length. The wide range of accessories available includes PVC, Nylon, and Halogen-free materials, making it widely compatible with all kinds of electronic components.

The OSTTA190161B terminal block is designed to connect two or more circuits with wire insulation supports, resulting in electrical resistance between the two terminals. This is achieved in two ways, either a pressure connection with two screws or a slot connection which allows easy insertion of wires without screws. The pressure connection is suitable for connecting two or more wires of about 1.5 sq.mm with a contact resistance less than 8 milli-ohm. This type of connection helps to reduce resistance values and keeps the temperature of the two terminals stable during a power surge.

The slot connection, on the other hand, is used for connecting small conductor wires such as signal wires of sizes ranging from 0.3 to 0.7 sq.mm. This is provided by a combination of copper alloy insert and an integrated ultra-high resistant thermoplastic interface which ensures a long life connection. The Gold-plated brass screw contacts are designed to prevent corrosion and improves connection reliability.

In conclusion, there are a multitude of uses for OSTTA190161B terminal blocks in the wiring of electronic appliances. The gold-plated brass screws ensure reliable and long-lasting connections, while the modular snap-in board mount design allows for easy installation. The two connection methods provided ensures ideal connections regardless of the size of the conductor wire. Besides, the wide range of accessories allows for compatibility with numerous components, making it an extremely versatile device for wiring applications.
