ที่ 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 (เลขที่) ผู้ติดต่อ + 1 set of Normally Closed (เอ็นซี) ผู้ติดต่อ, suitable for circuit scenarios requiring multi-channel signal control.
แรงดันไฟฟ้าที่ได้รับการจัดอันดับ:
Alternating Current (เครื่องปรับอากาศ): Maximum 660V (50/60Hz), compatible with common industrial voltages such as 220V, 380วี, and 400V.
Direct Current (ดี.ซี): Maximum 250V, covering low-voltage control circuits such as 24V, 48วี, and 110V.
จัดอันดับปัจจุบัน:
AC-15 Load: 1.6ก (220วี), 0.95ก (380วี), 0.9ก (400วี).
DC-13 Load: 2.75ก (12วี), 1.375ก (24วี), 0.69ก (48วี).
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 (เช่น, CJX2-09, CJX2-12, ฯลฯ), 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. การติดตั้งและการเดินสายไฟ
วิธีการติดตั้ง: 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 มาตรฐาน), suitable for environments ranging from -5℃ to +40℃.
Certifications: Has passed CCC Certification (China Compulsory Product Certification) and complies with GB/T 14048.5 และไออีซี 60947-5-1 มาตรฐาน.
5. ราคาและช่องทางการซื้อ
ราคาตลาด: The unit price is approximately 5-8 หยวน (bulk purchases can be as low as below 5 หยวน), with specific prices varying by sales platform and promotional activities.
Purchase Channels:
E-commerce Platforms: Sold by authorized distributors (วอทส์แอพพ์: 0086-13811255435).
Inventory Status: Most platforms show sufficient inventory, and same-day delivery service is available in some regions.
6. สถานการณ์การใช้งานทั่วไป
การควบคุมอุตสาหกรรม: Expand the control signals of contactors in automated production lines to realize logical control such as motor forward/reverse rotation and sequential start-stop.
สมาร์ทโฮม: 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: ก่อนการติดตั้ง, 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: หลีกเลี่ยงการใช้ในที่ชื้น, dusty, or corrosive gas environments; take protective measures if necessary.
สรุป
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.
