The unique
Model MM micro-miniature ROTOCON is a breakthrough in packaging technology.
Like all high performance ROTOCON designs, the MM has low resistance, low
capacitance, no measurable noise, and is completely sealed. With a current
rating of 5A, the MM is ideally suited to handle both power inputs and
sensitive instrumentation signals coming from thermocouples, thermistors,
strain gages, and accelerometers. The MM's small size (1 1/8 inches in
diameter, 1/4 inch shaft) allows it to fit into tight mechanical layouts.
Vibration and mounting orientation have no effect on electrical integrity.
Torque requirements are kept to a minimum by the use of double ball-bearing
construction. The ROTOCON MM is environmentally sealed and is able to withstand
hostile environments with zero maintenance. Standard models can be customized
to fit your existing equipment. If space is not a problem, other ROTOCON
Series, such as the MX, should be considered.

Note 1: Dimensions subject to change without notice. If
precise dimensions are required, contact Meridian Laboratory.
Note 2: Add 0.16 inches to length "A" and 0.5 ounces to
the weight for each additional contact.
Note
3: Odd numbers of contacts are available.
Note 4: The maximum allowable number of contacts is dependent
on the size and type of wire needed to meet your requirements (teflon
insulated, thermocouple leads, coaxial cable, twisted shielded pairs, or any
combination of these). The maximum Teflon insulated wire gauge is
#22. |

| Specifications |
Mechanical
RPM: 0
- 3,000 RPM continuous.
Mounting: Any end-of-shaft
orientation is acceptable. Either the shaft or the housing must have a flexible
link to the supporting structure. Housing rotation can be prevented by an
optional support ring.
Housing: Corrosion resistant steel.
General: Permanently lubricated bearings at both ends. |
Electrical
Voltage:
Microvolts to 460 volts.
Current: Nanoamperes to 5 Amps.
Max.
Wire Gauge: #22 (MIL-W-16878 nickel plated, stranded copper wire with
Teflon insulation). See Note 4 above.
Frequency: DC-100MHz.
Stationary Contract Resistance: One milliohm (excluding lead wires).
Rotating Contact Resistance: Same as stationary resistance, no change
with RPM. |
Environmental
Ambient Temperature: Not
to exceed 160°F (70°C), assuming minimal heat flow through shaft and
housing mounts. If machinery surfaces are hot, use insulated mounting
system.
Relative Humidity: No effect. |
