DESCRIPTION
What is this?Through-wall terminal blocks are primarily used for electrical continuity and physical isolation on both sides of equipment enclosures or panels. They are widely used in power systems, electrical control cabinets, filter equipment, industrial energy storage systems, communication modules, relays, microcontrollers, alarm systems, automated production line modules, power adapters, etc., to achieve safe connections between internal and external circuits without compromising the seal.What will I get?Type: Terminal ConnectorPin: 4 PinPin Pitch: 3.5mm/0.14 inchesWire Diameter: 26-14AWGRated Current: 8AOperating Temperature: -40-+105°CTotal Size: 38 x 16.5 x 28mm/1.5 x 0.65 x 1.1inch(L*W*H)Package Includes: 4 Sets x Terminal Block ConnectorAre there any advantages of the product?The Through-Wall Terminal Connector enables safe and reliable transmission of current or signals from both sides of a device panel, supporting flexible installation and maintenance, and allowing for quick connection and disconnection between wires. Made of flame-retardant and durable PA66 plastic, they ensure reliable insulation and long-term use under high-temperature conditions, enhance circuit safety, and offer advantages such as low signal loss and high switching frequency.How to use it?No soldering required. Simply open the terminal block with a small screwdriver, insert a multi-strand or single-core wire, and tighten. Wires can be easily connected or disconnected using screws or spring clips, facilitating equipment installation, debugging, and maintenance.What should I notice?Ensure screws are fully tightened to prevent loosening. Do not exceed rated voltage and current, and avoid exposing terminals to excessive heat or humidity to ensure safe operation.
