Terminal blocks, or terminal boards, are electrical connection points between two components or wires. Wire-to-board terminal blocks, such as the OSTKO242151, provide a fast, easy and secure connection of wires to a printed circuit board (PCB). The devices are typically available in a selection of sizes and colors.

The OSTKO242151 terminal block is designed for power and signal applications and is suitable for 22–14 AWG wire sizes. This type of terminal block features screw clamp/pressure connection technology, which results in reliable connections and low contact resistance. It also offers superior electrical characteristics, chemical resistance, and is flame retardant and shockproof.

Application fields of the OSTKO242151 terminal block include industrial automation, appliance control boxes, medical equipment, programmable logic controllers, elevators, lighting systems, moving signs, valve and pump controllers, solar energy applications, and more.

In terms of working principle, the OSTKO242151 terminal block utilizes the pressure connection technology first developed by the Phoenix Contact company in 1979. Pressure connection technology uses a plastic contact wedge that is inserted between a conductor and a contact element. To make an electrical connection, a wire is inserted into the hole and pressed into place with thumb screws. The pressure connection technology ensures reliable contact between the wire and the conductors, and the resulting electrical connection can be up to 10 times better than with conventional screw contacts.

The screw connections on the OSTKO242151 terminal block are insulated, and the insulation material is typically Flame Retardant Grade V-0. Cable insulation is also clamped on the outside, which helps to protect users from electric shocks. The terminal block is easy to install, requires minimal amount of maintenance and is highly reliable.

The OSTKO242151 terminal block is also designed to reduce wiring space and time, since the connection is quick and secure. The blocks are designed for easy mounting on PCBs or other flat circuits, and can also be easily replaced as required.

Overall, the OSTKO242151 terminal block offers an easy and secure connection of wires to a PCB, and it is suitable for use in various applications including industrial automation, medical equipment and solar energy. The device utilizes pressure connection technology to ensure reliable contact between the wire and the conductors, and it is easy to install and maintain.
