This is the M4 Ruby stylus #A-5003-5744.

This straight stylus can be used for simple features with which direct contact can be made. Carbon fiber styli weigh around 20% less than tungsten carbide styli, making it a suitable material for long styli. Its thermal stability is also advantageous, particularly with very long styli, which makes it suitable for use in a production environment. Zirconia tips are more suitable for abrasive surfaces such as cast iron parts.

*This stylus is recommended for us with OMP400 and RMP600
