Characteristics

Daco's modular trackballs are available in two versions, MT4 and MT6, both of which have a list of options that include different ball sizes, control buttons and interfaces.

Of the two versions the MT4 has the higher specification and consequently most are used in military systems.

Conversely, the MT6 is usually the first choice for commercial requirements although they are also used in less extreme military applications.

Both series have the following characteristics	MT4 trackballs also have the following additional characteristics

High reliability	Anodised main structure to give extra corrosion resistance
Very smooth action	Fully floating drip seal
Quiet operation	High temperature components on interface circuit boards
Extremely robust	Operating temperature range extended to -40 to +70^oC
Low start up and operating force	Aluminium top flange to reduce products of combustion
Operating force unaffected by direction of rotation	Warranty extended to 3 years
Operates at any angle of mounting	Uses wire with dual wall insulation combining radiated polyalkene and radiated polyvinylidene fluoride. This wire has low toxicity products of combustion and meets a wide range of specifications including MIL W 81004 and DEF STAN 61-12 part 18.
Operates even under heavy vibration
When spun to make large movements the ball, and hence cursor, direction remains linear i.e. does not exhibit a curving response
Long warranty. (Minimum 2 years)
Manufactured using an ISO 9000 approved quality system.
