GENERAL INFORMATION 1. YJQ-W1A is compatible with the M22520/2-01 which is widely used for the crimping of wires and contacts in electronic connectors. 2. Wire crimp range: 20AWG (0.52mm^2) to 32AWG (0.0316mm^2). WORKING PRINCIPLES 1. Crimping Method The crimping tool adopts curve propulsion mechanism, its applied force transfers through four curves in the head cavity of the right plier handle to the four indenters. The four intenders do the centripetal linear motion, which makes its front-end teeth crimp the contact to complete the crimping process. The cycle controlled precision ratchet assures the consistency of impression and the crimping quality of wires and contacts. 2. Crimping Range Adjustment The crimping tool has eight selector numbers; the accurate data are listed as follows: 3.Gaging Instructions “GO” Gaging: keep the tool in fully closed position, insert the green “GO” gage end into the indenter, it should be easy to enter, otherwise, the selector gear is incorrect. “NO GO” Gaging: keep the tool in fully closed position, insert the red “NO GO” end into the indenter, it can’t pass through completely, otherwise, the selector gear is incorrect.
