Renishaw: RG4 READHEADS FOR RTLR40 or RTLR40-S RGH45A30L00L

Renishaw’s RGH45 readhead offers all the benefits of the market proven RG4 linear encoder system – high-speed, non-contact performance with filtering optics to guarantee reliable performance over dirt, contamination and scratches.

The RGH45 readhead is designed for use with Renishaw’s high-accuracy stainless steel RTLR40 tape scale. Enclosed within a rugged die-cast housing, the readhead uses proven solid state components to give outstanding reliability.

Dual limit switch sensing is also included as standard to provide dedicated signals for each end-of-axis indication, together with a repeatable reference mark (datum). Installation is quick and easy to achieve thanks to generous readhead set-up tolerances and a rapid scale installation technique that uses the motion of the axis to lay the scale, which is then locked to the substrate via a single clamp fixed with Loctite®. Renishaw’s unique set-up LED indicates when optimum conditions have been achieved, removing the need for complicated oscilloscopes or set-up equipment.

RGH45 is available with self-adhesive RTLR40-S tape scale or RTLR40 with Renishaw’s unique FASTRACK ™ track system that allows easy scale replacement –ideal for long machines that need to be sectioned for transit. Both scale types feature high-accuracy graduations marked directly onto stainless steel, without any coatings, providing immunity to damage from harsh solvents. These added benefits give RGH45 readheads greater flexibility, making them ideal for use in a variety of applications including linear motors, FPD manufacturing, electronics assembly and test, printing machines and a variety of high-speed motion control systems
