AST1250504 is a terminal block used in Wire to Board connection field, which has features of excellent connection performance, various models and sizes, and simple installation. It is widely used in the fields such as power supply, communications, lighting control and industrial control.

The AST1250504 is a standard 2.5mm pitch, 5 circuit height terminal block with 1 to 5 poles. The product’s built in lanceless spring-loaded structure provides positive locking and push button for polarization. An optional clamp provides further secure protection for locking and polarization. With its high contact rating up to 16A at 300V, the AST1250504 is suitable for power, ground and signal distribution. Realizing secure conduction for big current is also available by using available conductor with different sizes from 14 AWG to 24 AWG (2.1mm2 to 0.14 mm2). The AST1250504 is easily attached with a single mounting hole, or may be applied using two or four mounting posts. Plated steel and copper alloy finish ensure good heat dissipation and mechanical strength.

In addition, the AST1250504 is compliant with the RoHS 2 standard with lead-free terminal design, post Tin plating and double solder tail. The mechanical durability of 10,000 mating cycles makes it ideal for applications that require many connections and dis-connections. With its superior electrical, mechanical and contact reliability, the AST1250504 enables excellent connection among different components of a finished product.

The Working principle of AST1250504 is simple and reliable. First, the square section insert must be unloaded then inserted into the wire gate of the terminal. To ensure electrical contact and physical connection between them, a retention force must be generated. The retention force is like an embracing force, to firmly lock and hold the wire and its part connected to it. A programmed retention system is used to create this retention force, and then a polarized component will ensure reverse insertion is prevented during installation. With its mechanical durability, the AST1250504 provides secure and reliable connection for big current transmission and long time electrical and mechanical reliability.

AST1250504 is an environment friendly device, available in various sizes from 1-5 poles. The product’s built in lanceless spring-loaded structure provides efficient locking and orientable functions. Its flexibility also enables secure wire connection for big current transmission. With its superior electrical, mechanical and contact reliability, the AST1250504 is the ideal Terminal Block for power supply, communication, lighting control and industrial control applications.
