The K-TSA50 series are waterproof and vandal-proof (over 20 Joules impacts) industrial trackball units. These units are completely stainless steel.
The IP68 waterproof level of the trackball uses Optical Navigation Technology with solid state sensing. The trackball is maintenance free as there are no moving parts except for the ball.
The unit has an appealing and robust look, the carrier plate, cover ring, the three anti-vandal switches and the housing all made of high grade stainless steel.
The unit has combo PS/2 & USB output with auto-recognition. The use of stainless steel ensures the best resistance in salty or greasy environments.
