P50 2" Optical Trackball

P50

Description

First in the line of optical trackballs, the P50 is the industry's first totally waterproof and submersible trackball device. In fact, the P50 works perfectly even when fluids such as beer, coffee, cola, and even ultrasound gels are poured into them to the point of overflowing. The P50 is solid-state, low maintenance, and is available in a range of options.

Features

Solid State Optical Navigation Technology

Totally Waterproof (IP68)

ESD Protected (Impenetrable Barrier)

Adjustable Friction Control

Fixed and Removable Ball Versions

Self-draining/back flushing Models

Anti-vandal Mounting Options

OEM Custom Resolutions

Decontamination Friendly

P50 Model Versions:


Free running ball; minimal tracking force of 10 grams.	Increased tracking force of 60 grams; ball does not spin freely. Seal-ring scrapes dirt from ball.

Adjustable tracking force from 10 to 120 grams. Ball can be removed for easy wash-off.	Underside view showing sealed plastic ball housing.
