Klemens 12 Pole Set: 5.08mm 12-Pole Plug-in PCB Terminal Block Set (16A, 250V)

The 12-Pole Plug-in Terminal Block Set is a high-density connection interface designed for heavy-duty industrial and elevator applications. Featuring a 5.08mm pitch, this connector set allows for the centralized wiring of up to 12 signal or power lines, making it indispensable for main control boards, inspection boxes, and complex signal distribution units in elevator systems.

Technical Specifications: 12-Pole Terminal Set

Product Description

The 12-Pole 5.08mm Terminal Block Set is a critical component for organizing the extensive wiring required in modern elevator systems. Unlike smaller connectors, this 12-pin variant is specifically used where high-density signal transfer is required between field devices and the Printed Circuit Board (PCB).

Where is it used in Elevators?

• Main Control Units: It is frequently found on main controller boards (such as Arkel ARL series or Arcode peripherals) to handle grouped signals like safety chain inputs (120-140 series), multiple programmable inputs, or call button return wires,.
• Inspection Boxes (Revizyon Kutusu): Used inside the inspection box on top of the car to connect the traveling cable wires to the local inspection board (e.g., connecting car calls or door operators).
• Connection Boards (KBK/XCT): Ideal for connection distribution boards like the KBK-12 or KBK-7, where multiple shaft signals are aggregated and transferred to the main controller,.

Reliability and Safety: Safety is non-negotiable in lift systems. This terminal block features a rugged Polyamide (PA6) housing that is self-extinguishing (UL 94 V0). The silver-plated brass pins ensure low contact resistance, preventing overheating even under the full 16A load. The screw connection system allows for a torque of 0.4 Nm, ensuring that wires ranging from 0.25mm² to 2.5mm² remain securely fastened during elevator travel.

Frequently Asked Questions (FAQs)

Q1: Can I use this 12-pole connector for mains power (220V) connections?

Yes, the terminal is rated for 250 V and 16 A. It is suitable for carrying mains voltage for safety circuits, door motor power, or lighting circuits, provided the wire sizing is appropriate,.

Q2: Is this compatible with Arkel control boards?

Yes. Arkel and many other elevator controller manufacturers utilize the standard 5.08mm pitch for their I/O and power terminals. This set is compatible with boards like the KBK-12, KBK-7, and various ARL series extension terminals,.

Q3: What happens if I need fewer than 12 poles?

While this is a 12-pole set, these terminal blocks are modular. However, for a designated 12-pin header on a PCB, you must use the matching 12-pole socket. If you require fewer connections for a custom project, standard 2, 3, or 4-pole versions are also available in the 5.08mm series.

Q4: How do I separate the plug from the header for maintenance?

he “plug-in” design allows you to pull the female socket (with wires attached) straight off the male header (soldered to the board). This instantly isolates the wiring from the electronic card, facilitating safe and quick board replacement without rewiring.
