KNIPEX
Frequently asked questions
Common questions about KNIPEX from 3G Electric.
What is the crimping range of KNIPEX controlled-cycle crimping pliers?
KNIPEX controlled-cycle crimping pliers, such as the MPN 97 52 36, are designed for crimping butt connectors, insulated terminals, and plug connectors. The controlled-cycle mechanism ensures a complete crimp cycle before the pliers release, which helps maintain consistent crimp quality. The specific crimping range depends on the connector type and size; for detailed specifications, refer to the product datasheet. These pliers are 8 5/8 inches long and weigh 1.07 lb. They are not insulated and are intended for use on de-energized circuits or with appropriate personal protective equipment.
What are the specifications of KNIPEX VDE insulating mats?
KNIPEX VDE insulating mats, such as MPN 98 67 05, are made of rubber and are VDE-certified for AC use up to 1,000 V. They measure 19 5/8 inches by 19 5/8 inches. These mats provide electrical insulation for work areas such as electrical panels, test benches, and industrial workstations. They are compliant with VDE standards, which specify requirements for insulating materials used in electrical applications. The mats are red and have a thickness that provides dielectric strength for the rated voltage. They are suitable for use in environments where protection against electric shock is required.
What is the difference between KNIPEX internal and external retaining-ring pliers?
KNIPEX internal retaining-ring pliers are designed for installing and removing circlips from bores, while external retaining-ring pliers are for circlips on shafts. For example, the internal plier MPN 48 11 J3 handles bore diameters from 40 mm to 100 mm, and the external plier MPN 49 11 A3 handles shaft diameters from 40 mm to 100 mm. Both have a tip diameter of 0.091 in and an overall length of 8 7/8 in. Smaller sizes are available, such as the external plier MPN 49 11 A1 for shaft diameters from 10 mm to 25 mm, with a 0.051 in tip diameter and 5 1/2 in overall length. These pliers feature atramentized (phosphate-coated) finishes for corrosion resistance.
What are the jaw capacities of KNIPEX tongue and groove pliers?
KNIPEX tongue and groove pliers are available with V-jaw or flat-jaw configurations. The V-jaw plier MPN 87 51 250 has a push-button adjustment with 19 jaw positions, a maximum jaw opening of 1 1/4 in, and an overall length of 10 in. The flat-jaw plier MPN 86 02 180 has a smooth gripping surface, a maximum jaw opening of 1 1/2 in, and an overall length of 7 1/8 in. These pliers are used for gripping and turning nuts, bolts, and pipes. The push-button adjustment allows quick size changes without the need for a traditional slip-joint mechanism. The flat-jaw model is suitable for parallel clamping of flat workpieces.
Are KNIPEX tools manufactured in Germany?
KNIPEX is headquartered in Wuppertal, Germany, and maintains manufacturing facilities in Germany. Many KNIPEX tools are produced in Germany, and the country of origin is typically stated on the product packaging or datasheet. For example, the auto-adjusting wire ferrule crimper MPN 97 53 14 lists Germany as the country of origin, subject to change. KNIPEX operates multiple production sites and sources materials globally. The company's quality management systems are certified to ISO 9001. For specific origin information, refer to the product documentation provided by 3G Electric.
What is the purpose of the controlled-cycle mechanism on KNIPEX crimping pliers?
The controlled-cycle mechanism on KNIPEX crimping pliers, such as the MPN 97 52 36, ensures that the crimping cycle is completed before the pliers can be opened. This prevents partial crimps and helps maintain consistent crimp quality. The mechanism is designed for crimping butt connectors, insulated terminals, and plug connectors. The pliers have a deluxe cushion grip for comfort during repetitive use. They are 8 5/8 inches long and weigh 1.07 lb. The controlled-cycle feature is particularly useful in production environments where crimp consistency is critical. These pliers are not insulated and should be used on de-energized circuits.
