MOTION CONTROL: Haydon Kerk Motion Solutions Inc. offers the LRS Linear Rail System in a variety of configurations, both motorized and non-motorized. These precision linear rail systems consist of a stationary base and a load bearing carriage that travels along a rigid extruded aluminum rail. The LRS Linear Rail System is available with several in-line motor options including a single stack or double stack size 17 stepper motor, a stepper motor with an integral chopper drive, or the IDEATM programmable linear actuator, consisting of the stepper motor, drive, and controller programmed through a graphic user interface (GUI). The LRS is also available without a motor, easily allowing the designer flexibility to integrate with a variety of motor types and belt and pulley configurations.The LRS carriage design is unique; it controls slide bearing play with a patent pending self-adjusting linear bearing. Integrated along the entire length of the rail system are “T” slots allowing the ability to mount limit switches and sensors. The lead screw is made from 303 stainless steel and can be configured with optional Black Ice TFE coating for durable and permanent lubrication. The LRS Linear Rail system comes standard with a general purpose lead screw nut, but for extreme control, the system can be configured with an optional Kerk CMP or WDG precision anti-backlash nut.
Kaspersky Labs indicated at its February meeting that cyber attacks are far more sophisticated than previous thought. It turns out even air-gapping (disconnecting computers from the Internet to protect against cyber intrusion) isnít a foolproof way to avoid getting hacked. And Kaspersky implied the NSA is the smartest attacker.
