OSTTR021550 is a horizontal, feed-through type terminal block manufactured by Phoenix Contact. It is widely used in the fields of electronics, automation and other industrial applications and it represents a key part of their Wire to Board family of Terminal Blocks.The OSTTR021550 terminal block is designed primarily for the purpose of connecting electrical wires, both to each other and to adjacent components.They are available in various versions depending on the type of connection (screw or spring clamp/push in) and have a wide range of contact designs, pitch distances, voltage values and wire spacing. The OSTTR021550 terminal block is made of thermoplastic Polyamide 6 (PA6) and other materials (e.g. copper).It is available in four different color combinations (black, green, grey and yellow).The block is divided into two parts: the top half (where the cables are inserted and held in place) and the bottom half (where the terminals are located). It is also UL and CSA approved and has a continuous operating temperature of -40°C to +110°C.As far as installation is concerned, the OSTTR021550 terminal block is relatively easy to install. It is simply mounted onto a printed circuit board (PCB) or terminal strip by means of four mounting holes. For connection between the block and the PCB, the manufacturer provides a range of options, such as insulation displacement connectors, rivets, screws and push-in terminals.The OSTTR021550 terminal block also offers a significant electrical connection safety feature - short circuit protection. This process provides instant protection in the event of a short circuit, preventing damage to both the terminal block and the connected device.To ensure that there is a reliable connection between the terminal block and the connected device, the OSTTR021550 terminal block is equipped with an oversized screw connection. This provides a secure and reliable connection of up to 27Nm torque. In addition, the OSTTR021550 terminal block also offers an adjustable tension level for improved electrical performance. Finally, the OSTTR021550 terminal block provides excellent strain relief for the connected wires, ensuring that they remain firmly in place and preventing them from becoming loose or coming apart.In conclusion, the OSTTR021550 terminal block from Phoenix contact is a reliable and cost effective solution for connecting wires to adjacent devices. It is designed to provide secure and reliable connections, and is UL and CSA approved for use in hazardous applications. Furthermore, it features an adjustable tension level and a strain relief feature to ensure a reliable connection.
