Klemens 3 Pole Set 5.08mm 3-Pole Plug-in PCB Terminal Block Set (16A, 250V)

This 3-Pole Terminal Block Set is a high-quality, plug-in connection solution designed specifically for elevator control systems and industrial PCB applications. Featuring a standard 5.08mm pitch, it consists of a female screw-clamp plug and a corresponding male header, facilitating secure signal transmission and easy maintenance for lift controllers.

Technical Specifications: 3-Pole Terminal Set

Product Description

The 5.08mm 3-Pole Terminal Block Set is an essential component for modern elevator electronics, offering a reliable interface between field wiring and Printed Circuit Boards (PCBs). The set typically includes a female socket (plug) with a screw-cage clamp mechanism and a male header (soldered to the PCB). This pluggable design allows technicians to easily disconnect wiring harnesses during maintenance or board replacement without unscrewing individual wires.

Robust Engineering: Engineered for industrial environments, the terminal block features a rugged Polyamide (PA6) housing that meets the UL 94 V0 flammability standard, ensuring safety in control cabinets. The screw connection mechanism (M2.5) provides a high clamping force, capable of securing wires up to 2.5mm² (14 AWG), ensuring that connections remain tight even under the vibrations common in elevator machine rooms,.

Application Versatility: Ideally suited for Arkel control boards (such as ARL-series or ARCODE peripherals) and generic industrial automation, this 3-pole connector handles up to 16A of current. It is compatible with various configurations, including 90° and 180° open or closed headers, providing flexibility for different PCB layouts and cable routing requirements.

Frequently Asked Questions (FAQs)

Q1: What is the maximum wire size compatible with this terminal block?

The terminal accepts solid and stranded wires with a cross-section of up to 2.5 mm² (approximately 14 AWG). For wires with ferrules, the maximum recommended size is 1.5 mm².

Q2: What is the recommended stripping length for the wires?

To ensure a secure connection without exposing live conductors, the insulation should be stripped back by 7 mm before insertion into the terminal.

Q3: Can this terminal block withstand high temperatures?

Yes, the housing is made of high-quality Polyamide (PA6) and is rated for an operating temperature range of -40°C to +100°C, making it suitable for demanding elevator control environments.

Q4: Is the male header included in the set?

This description refers to the “Set,” implying both parts are needed for a connection. However, in catalog terms, the Female Socket (plug) and Male Header (PCB part) are often listed as combinable but distinct SKUs (e.g., SBDK 5.08-D/3 for the socket and SBDK 5.08-E1/3 for the header) to allow for different PCB angles (90° or 180°),. Please confirm the specific combination required for your PCB layout.
