Klemens 24 Pole Set: 5.08mm 24-Pole Plug-in PCB Terminal Block Set (16A, 250V)

The 24-Pole Plug-in Terminal Block Set is a high-density, heavy-duty connection interface designed for complex signal distribution in elevator systems. Typically used as the primary interface for traveling cables (flat cables), this connector set ensures the secure transmission of up to 24 separate signal and power lines between the elevator car, inspection box, and the main control panel.

Technical Specifications: 24-Pole Terminal Set

Product Description

The 24-Pole 5.08mm Terminal Block Set is a critical component in the architecture of modern elevator control systems. As elevator technology advances, the number of signals required between the moving car and the static machine room increases. This 24-pole connector serves as the central “nervous system” connection point.

Primary Applications in Elevators:

• Traveling Cable Termination: This is the standard connector used to terminate the flexible flat cable entering the Car Top Inspection Box (Revizyon Kutusu). It carries vital signals including door operator commands, safety chain inputs (stop buttons, limit switches), and car operating panel (COP) data.
• Main Controller Boards: It is frequently used on mainboards (such as Arkel ARL-500 or ARCODE peripherals) to connect large groups of I/O signals or shaft cable bundles,.
• Distribution Boards (KBK): Ideal for connection boards like the KBK-10 or similar distribution units where high wire counts are consolidated before entering the main CPU,.

Reliability and Safety: Given its role in carrying safety signals, reliability is paramount. The terminal features a PA6 polyamide housing resistant to high temperatures (up to 100°C) and flammability (UL 94 V0). The high-pressure screw clamp ensures a gas-tight connection for wires up to 2.5mm², preventing signal loss or overheating even after years of vertical movement cycles.

Frequently Asked Questions

Q1: Is this connector suitable for the main traveling cable (flat cable)?

Yes, this 24-pole set is perfectly suited for terminating the individual cores of the flat traveling cable inside the inspection box or control panel, managing a mix of power and signal wires.

Q2: Can I separate the 24-pole block into smaller sections?

Most high-pole count terminals are modular. However, for structural integrity and ease of plugging, it is recommended to use the specific block size required. If a single 24-pole piece is not available, two 12-pole sets are often mounted side-by-side to achieve the same pin count.

Q3: What is the maximum current this block can handle per pole?

The terminal is rated for a nominal current of 16 A per pole. This is sufficient for almost all elevator control signals, door motor power supplies, and safety chain circuits,.

Q4: Does the set include both the plug and the PCB header?

Yes, the “Set” designation implies it includes both the Female Socket (for wire connection) and the Male Header (for soldering to the PCB). This ensures a complete mating pair for immediate installation.
