Frequently asked questions
Ring Terminal Selection and Assembly FAQ
When should I use the TO25552G-1201 ring terminal?
TO25552G-1201 is a ring terminal in ZUCH’s Ring Terminal Series. A ring terminal has a closed eye for a stud connection. Confirm the fastener, installation access and retention requirements for your assembly.
How do I select the wire and stud size for TO25552G-1201?
The catalog lists a 20-22AWG conductor range, a M2 bolt size. These are separate dimensions: match both the conductor and stud to the current drawing. Confirm the assembly requirements with ZUCH.
Can I replace a ring terminal with a spade terminal?
A closed ring and an open fork have different retention geometry. Matching the wire range or bolt size alone does not establish interchangeability. Confirm the approved terminal shape, fastener and retention requirements before substituting TO25552G-1201.
Which crimping tool should I use for TO25552G-1201?
Select tooling for the listed 20-22AWG wire range and the exact terminal geometry. Ask ZUCH for the approved die, wire-preparation and crimp specification. A general-purpose crimper is not automatically suitable. Confirm the assembly requirements with ZUCH.
How much current can TO25552G-1201 carry?
The public catalog does not publish a rated current for this exact model. Do not derive an ampere rating from terminal color, wire range or a similar part; request the application limit from ZUCH. Confirm the assembly requirements with ZUCH.
What material and finish are specified for TO25552G-1201?
The specified material is Copper Alloy. The surface treatment is listed as Matte Tin-plated. Match the finish to the approved mating contact and environment; request the material declaration or drawing if the project requires a specific alloy or coating thickness. Confirm the assembly requirements with ZUCH.
Can TO25552G-1201 be used in heat, moisture or vibration?
The catalog records a usage environment of -40°~105°. Confirm the unit and test conditions on the current drawing. The terminal entry does not establish a sealed assembly or a vibration-test result. Confirm the enclosure, insulation and environmental validation required for your application.
How do I check the finished connection made with TO25552G-1201?
Check conductor placement, terminal retention and the connection against the approved application drawing. Ask ZUCH to specify the applicable mechanical and electrical acceptance limits; a visual check alone does not establish the complete assembly rating. Confirm the assembly requirements with ZUCH.
