Delixi Contactor Auxiliary Contact F4-11

The Delixi Contactor Auxiliary Contact F4-11 is an accessory specifically designed to expand the control functions of contactors.

1. Basic Parameters and Functions

Contact Configuration: 1 set of Normally Open (NO) contacts + 1 set of Normally Closed (NC) contacts, suitable for circuit scenarios requiring multi-channel signal control.

Rated Voltage:

  Alternating Current (AC): Maximum 660V (50/60Hz), compatible with common industrial voltages such as 220V, 380V, and 400V.

  Direct Current (DC): Maximum 250V, covering low-voltage control circuits such as 24V, 48V, and 110V.

Rated Current:

  AC-15 Load: 1.6A (220V), 0.95A (380V), 0.9A (400V).

  DC-13 Load: 2.75A (12V), 1.375A (24V), 0.69A (48V).

Control Capacity: 3600VA for AC, 33W for DC, capable of driving electromagnetic coils or amplifying signals.

2. Compatible Contactor Models

Core Series: Delixi CJX2 series contactors (e.g., CJX2-09, CJX2-12, etc.), which can be directly mounted on the top of the contactor.

Compatible Models: Some documents indicate compatibility with CJX4 and LC1 series (specific model compatibility needs to be confirmed).

3. Installation and Wiring

Installation Method: Fastened via a top snap-on structure without tools, supporting direct front insertion and removal.

Terminal Blocks:

  - Can connect single-strand or multi-strand wires of 0.5-1.5mm² (wires need to be stripped before direct insertion into terminal holes).

  - The terminals are made of flame-retardant nylon, featuring excellent anti-aging and insulation performance.

4. Materials and Certifications

Contact Material: Silver alloy contacts, which have high wear resistance, can achieve self-cleaning function, and ensure long-term reliable connection.

Insulation Material: The shell is made of high-temperature resistant flame-retardant nylon (complying with UL94 V-0 standard), suitable for environments ranging from -5℃ to +40℃.

Certifications: Has passed CCC Certification (China Compulsory Product Certification) and complies with GB/T 14048.5 and IEC 60947-5-1 standards.

5. Price and Purchase Channels

Market Price: The unit price is approximately 5-8 RMB (bulk purchases can be as low as below 5 RMB), with specific prices varying by sales platform and promotional activities.

Purchase Channels:

  E-commerce Platforms: Sold by authorized distributors (WhatsApp: 0086-13811255435).

Inventory Status: Most platforms show sufficient inventory, and same-day delivery service is available in some regions.

6. Typical Application Scenarios

Industrial Control: Expand the control signals of contactors in automated production lines to realize logical control such as motor forward/reverse rotation and sequential start-stop.

Smart Home: Cooperate with PLCs (Programmable Logic Controllers) or relays to realize multi-channel linkage control of devices such as lights, curtains, and air conditioners.

Power System: Add auxiliary contacts in power distribution cabinets for status indication, fault alarm, or remote monitoring.

7. Usage Precautions

Compatibility Verification: Before installation, confirm whether the contactor model supports F4-11 (especially non-CJX2 series) to avoid size or interface mismatch.

Load Matching: Select the appropriate contact type (AC/DC) according to the voltage and current of the actual control circuit to prevent burnout due to overload.

Wiring Specifications: Wires need to be stripped to an appropriate length (approximately 8-10mm). Ensure that terminals are tightened without looseness to prevent faults caused by poor contact.

Environmental Conditions: Avoid use in humid, dusty, or corrosive gas environments; take protective measures if necessary.

Summary

With its high compatibility, stable performance, and cost-effectiveness, the F4-11 has become a preferred solution for expanding the control functions of contactors in industrial and civil fields. It is recommended to choose official channels for purchase to ensure product quality and after-sales service.
