Hollow Shaft Sample Transporter DN40CF

Product code: RMHS40-XXXX-YYYY

The RMHS40 is based on the RM40 sample transporter. It's tubular shaft is considerably lighter. This helps to reduce thermal conductance. It is commonly used as a manipulator for vertical sample insertion into cryogenic SPM's but of course it's lighter hollow shaft offers advantages for other applications as well. In particuar, long travel ranges can be realized up to a maximum of 2300mm.

In most applications, the RMHS is mounted vertically. For safety reasons it's strongly recommended to use it in combination with an IVBR in-vacuum brake, to prevent the inner shaft from suddenly dropping in case the magnetic coupling should slip from the user's grip. An optional TSRMBD belt drive facilitates handling once the height of the system and/or length of the sample transporter make it hard to reach and manipulate.

  • Customized stroke: Specify XXXX min. 50mm / max. 2300mm
  • Customized retracted length: Specify YYYY min. 20mm / max. 200mm

Customized Example: RMHS40-1800-0100 = Hollow Shaft Sample Transporter DN40CF, 1800mm linear travel, retracted shaft length 100mm.

RMHS40 compatible options and accessories: See below.
