If you have need of a customized linear positioner delivered quickly and at a non-custom cost, Dynact wants you to take a look at their LP100 series. Though compact, they offer stroke lengths of up to 20 feet using Vee, Acme, and zero-backlash Acme screws. The positioners are driven by an in-line stepper motor or 24V dc servo motor and offer options such as: electromechanical fail-safe brakes, magnetic switch relays, environmental sealing, magnetic reed switches, linear potentiometer, optical encoders, and special mounting options. An LP100 can position loads up to 60 lbs at up to 12 in/sec, with a maximum thrust of 200 lbs. They can be supplied with a matching Indexer/Driver for stepper motor models, or controller and amplifier for the dc servo positioners. Dynact, Inc., Product Code 4210.
