MD16N/MD16A (CF16, 1.33in OD) MagiDrive Series Magnetically Coupled Rotary Motion Feedthroughs

Representative Image

MD16N/MD16A (CF16, 1.33in OD) MagiDrive Series Magnetically Coupled Rotary Motion Feedthroughs

Features

True UHV rotation
High torque to size ratio
No bellows or dynamic seals
Bakeable to 250°C
Zero-backlash under low load

The standard MD16N drive provides sufficient torque for the majority of miniature feedthrough requirements. The MD16A variant maintains the same dimensions as the MD16N but provides increased levels of torque. The MD16A provides the highest torque on the market for a CF16 flange and is ideal for shutter applications.

The MD16N and MD16A benefit from our simple actuation upgrade options that enable a manual version to be upgraded with motorization or pneumatic actuation via a simple 'do it yourself' upgrade kit.

Manual Options

Code	Actuation Method	Description
T	Standard MD Thimble	A calibrated thimble gives a visual indication of the drive position with one degree increments. It is fitted with the friction control system as standard.
P	Timing Pulley	A pulley is mounted on the end of the drive allowing users to install their own motor assemble.
D	Dual Shaft	MagiDrives can be supplied with both input & output shafts. This allows the customer to retrofit their own motorization option or to fit a position encoder.

Motorization Options

Code	Actuation Method	Description
IS	In-Line Stepper Motor	A co-axially mounted stepper motor providing minimum lateral footprint.
ISS	In-Line Stepper Motor with Home Sensor	As above but with a rear disk & switch assembly, providing a datum point home postion.
ISE	In-Line Stepper Motor with Rotary Encoder	A co-axially mounted stepper motor providing minimum lateral footprint with a rotary encoder to provide positional data
ISES	In-Line Stepper Motor with Rotary Encoder & Home Sensor	A co-axially mounted stepper motor providing minimum lateral footprint with a rotary encoder to provide positional data and single optical sensor for home positioning whilst allowing continuous rotation
ID	In-Line DC Motors	A co-axially mounted DC motor providing minimum lateral footprint.
ISM	In-line SMART motor only	A co-axially mounted Smart DC motor providing minimum lateral footprint
ISMS	In-Line DC Motors with Home Sensor	A co-axially mounted Smart DC motor providing minimum lateral footprint with a single optical sensor for home positioning whilst allowing continuous rotation

Pneumatic Options

Code	Actuation Method	Description
RA	Pneumatic In-Line Rotary Actuator	Pneumatically actuated MagiDrives are fitted with an adjustable rotary actuator providing from 30-170° sweep. Flow controllers enable input and exhaust to be throttled to control speed.
RAI	Rotary actuator w/visual position indicators & reed switches	As above but fitted with two reed switches to provide position feedback for system interlock facilities. This option also includes LED's allowing the user to see the position of the shutter in open or closed states.

Gear Option Table

Each motorized MagiDrive is offered with a range of gearbox options allowing a variety of torque and spin speed solutions to be offered as standard. Special configurations are available on request.

Shaft & Bearing Options Table

Drive	Shaft Options	Bearing Options
MD16N, MD16A	000 - Standard Shaft 030 - 30mm Shaft	Z - Standard Bearing CE - Ceramic Bearing

NOTE:

Standard bearing: As standard, the MagiDrive range uses high performance molybdenum disulphide lubricated bearings providing long life and true UHV performance.
Ceramic bearing: Uses state-of-the-art ceramic bearing technology. The SiN bearings require no lubrication and provide smooth, ultra-clean performance.
