Product description

The Cryo Linear Drive (CLD) is a linear stage with an unrivaled 51.5 mm stroke in a compact and robust package. The combination of stepping and scanning functionality offers a solution for long stroke applications in cryogenic positioning. Optionally feedback can be fitted for closed loop control. Moving parts are made out of non–magnetic phosphor bronze to minimize interaction with external magnetic fields.

The RLS (Resistive Linear Sensor) is a resistive based sensor that can be added to selected positioners for position feedback. A wiper slides over a resistive track and the measured voltage is a measure of position. Resolution is determined by electrical noise and length of the resistive track. It is an absolute sensor, which means that it will give the actual position, even after recovering from a power shutdown. The RLS requires the RSM electronics module as voltage source and position readout. More info can be found in the Downloads section.

HV rated positioners can realistically be considered compatible with pressures as low as 1E-8 mbar. Lower pressures can be achieved by prolonged baking of positioners in vacuum at 100-150 deg C, depending on the type of positioner. Upon request JPE can provide such service at additional costs.
