Product Description

The PTV series of insulated terminals complies with IEC low-voltage electrical standards and is widely used in applications such as power distribution cabinets, PLC control panels, automation equipment, power tools, and construction machinery. Suitable for both indoor and outdoor environments, these terminals are critical components in low-voltage electrical systems.

Precision-manufactured from tin-plated pure copper - a material offering excellent conductivity and corrosion resistance - this series ensures secure and durable connections.

Designed for rapid connection scenarios, the pin-style design allows for direct insertion into terminal blocks. The integrated PVC insulation sleeve protects the connection point after the wire is inserted, effectively preventing electrical leakage and short circuits.

Utilizing cold-crimping technology, the terminals can be installed quickly and easily using specialized tools (equipped with a ratcheting mechanism), thereby enhancing work efficiency.

The insulation sleeves come in various colors (red, green, blue, and yellow) corresponding to different wire gauges, facilitating on-site selection and reducing the risk of installation errors.

Available in multiple lengths to accommodate varying connection depths, the series supports wire gauges ranging from 1.25 mm² to 5.5 mm².

FAQ

Question 1: What are the application scenarios for PTV insulated pin terminals?

Answer: PTV insulated pin terminals feature a pin-style connection design. Their metal pins can be inserted directly into terminal blocks or PLC module slots, enabling quick and easy "plug-and-play" electrical connections. They are widely used in PLC systems, automation equipment, low-voltage power distribution, and general industrial applications.

Question 2: What materials are used in the product? Does the PVC insulation sleeve provide protection?

Answer: The conductive core is made of high-quality tinned copper, ensuring reliable conductivity and oxidation resistance. The product is equipped with a flame-retardant PVC insulation sleeve that protects the conductive components while effectively preventing short circuits and electrical leakage.

Question 3: Why is the crimping process important? How is crimping quality verified?

Answer: If the crimp is too loose, contact resistance increases, leading to overheating during load operation; conversely, if the crimp is too tight, the copper strands may be damaged, reducing mechanical tensile strength. Using a ratcheting crimping tool ensures a tight fit between the copper strands and the metal sleeve; standard pull tests are subsequently performed to verify connection quality.

Question 4: Is custom packaging or distributor logo printing supported?

Answer: We offer OEM services, including custom outer packaging and distributor logo printing; pin specifications can also be customized to meet specific customer requirements. Costs for small-batch orders will be calculated based on specific needs.

Question 5: Can I request samples? What is the lead time?

Answer: We provide sample services, though a fee applies; fees for custom samples are refundable upon placement of a bulk order. The lead time for samples is 7 to 15 days, while the lead time for mass production orders depends on specific product specifications.

Question 6: Which standards do the products meet? What is the after-sales policy?

Answer: The products comply with relevant IEC standards for low-voltage connectors and undergo factory testing (including tensile strength and electrical performance tests). We provide replacement services for quality issues caused by manufacturing defects; however, the warranty does not cover problems resulting from incorrect model selection, improper use, or improper operation.
