Electrical complete connector 2‑pole Rittal 2500.640, conductor 0.25–1.5 mm², black/grey

Rittal 2500.640 is a two‑pole complete electrical connector intended for through‑wiring in control cabinets and panel installations. It accepts conductors with cross sections from 0.25 to 1.5 mm² and is supplied in a combination of black and grey. The connector is designed for low‑voltage signal and power circuits, for example 24 V DC applications, and is delivered in packs of five, suitable for industrial wiring and maintenance tasks.

Advantages

This two‑pole Rittal connector provides a compact, preassembled solution for through‑wiring that reduces assembly time compared with individual component assembly. Its conductor range from 0.25 to 1.5 mm² covers most common signal and low‑power control wiring sizes. The color contrast of black and grey helps with visual identification in panels, while the complete connector format ensures consistent electrical contact and straightforward replacement during service.

Suitable for

• Through‑wiring of control cabinets and distribution panels
• Panel and terminal block connections for industrial automation
• Low‑voltage signal circuits (for example 24 V DC) and sensor wiring
• Maintenance and retrofit work where compact, preassembled connectors are required

When it may not be suitable

This connector is intended for low‑voltage and low‑current applications using conductors within the stated 0.25–1.5 mm² range. It is not suitable for high‑current power distribution, mains voltage applications, or conductors outside the specified cross‑section range. For environments requiring special ingress protection, high vibration resistance, or specific certification profiles, alternative connector types or additional protective measures may be necessary.

Key specifications

• Number of poles: 2
• Conductor cross section range: 0.25–1.5 mm²
• Intended voltage level: low‑voltage/signal circuits (example: 24 V DC)
• Color: black and grey combination
• Delivery form: pack of 5 complete connectors
• Application: through‑wiring for control cabinets and panel wiring

How to use

Prepare the conductors by stripping the insulation to the recommended length for the connector type, then insert each conductor into the corresponding pole until it seats securely. Mount the connector in the intended through‑wiring position within the panel or terminal area following the cabinet layout. Verify mechanical retention and electrical continuity with suitable test equipment before applying operational voltage. Follow standard safety procedures for low‑voltage electrical work and consult system documentation for correct wiring polarity and routing.

What to consider before purchase

• Confirm conductor cross section falls within 0.25–1.5 mm²
• Ensure the connector's low‑voltage rating and pole count match the intended circuit
• Check color and mechanical dimensions fit the panel layout and identification scheme
• Assess whether environmental or certification requirements demand a different connector type

Usage recommendations

Use these connectors for organized through‑wiring in control cabinets and signal circuits; perform continuity checks after installation and keep spare connectors on hand for rapid maintenance or replacement.
