Wire Pin Material

The wire pins are made from a Copper Tin alloy (Phosphor Bronze) wire designated CuSn6 specification to DIN 17662, CW452K / EN 12166

 

Coating materials: 1-2 microns Nickel (Ni) & 4-6 microns Tin (Sn) 'brightplating'

 

All wires used are lead free

 

Solderability: To BS 2011

 

Methods of pin retention:

Blind hole method                                            Through hole with a 90° side leg

 

For improved pin retention the wire is 'crimped' to produce an area of upset which on the blind hole method is totally inserted into the bobbin. With the 'L' pin the crimp is partially inserted. The crimped area of the pin prevents 'push back' and the 90° bend prevents 'pull out'

 

The most popular sizes of pin are 0.6mm round, 0.635mm square and 0.8mm square

 

Bobbins can be pinned to any configuration as specified by the customer
