SL3.5/4/180F – WEIDMULLER

The WEIDMULLER SL3.5/4/180F (WEIDMULLER Order Number 1607520000) designates a PCB terminal block connector. Specifically, it is a single-level, four-pole connector with a 3.5mm pin spacing (pitch). The “180” indicates a 180-degree wire entry angle, meaning the wires enter horizontally relative to the PCB surface. The SL series employs a screw connection method for wire termination, providing a secure and reliable electrical connection. This connector is designed for through-hole mounting onto printed circuit boards. Electrical specifications include a rated voltage and current dependent on applicable standards (e.g., IEC, UL), which must be verified against the official datasheet. The housing material is typically a polyamide (PA) plastic, offering good insulation properties and mechanical strength.
