The ROTOCON
Model MX is Meridian Laboratory's most popular rotary contact
design. Covering a broad range of applications, the MX
has proven itself in thousands of "real
world" situations. From nanoamperes to 30 amperes, the MX
is used in applications ranging from low level instrumentation
signals to high power
pulses. The sealed contacts have low resistance, low capacitance,
and no induced noise up to the rated speed of 2000 RPM.
Tight environmental sealing is responsible for the MX's reputation
for continuous operation with zero maintenance. Surprisingly
small (1 5/8 inches in diameter,
½ inch shaft), the MX will typically fit easily into
existing equipment designs. The efficient, arc-free contacts
inherent in the ROTOCON design are
completely unaffected by vibration and mounting orientation.
Standard and customized MX's have solved the most difficult
rotating contact problems in a
wide range of industries.

Note 1: Dimensions subject to change without notice. If
precise dimensions are required, contact Meridian Laboratory.
Note 2: Add 0.33 inches to length "A" and 2.5 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 #14. Wires
can be connected in parallel for increased current capacity.

| Specifications |
Mechanical
RPM: 0
- 2000 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 is prevented by an anti-rotation bolt (standard) or
support ring (optional).
Housing: Corrosion resistant stainless
steel.
General: Permanently lubricated bearings at both
ends. |
Electrical
Voltage:
Microvolts to 460 volts.
Current: Nanoamperes to 30A.
Max.
Wire Gauge: #14 (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. |
