2. Rapid Enclosure Access
Screw-on cover allows quick enclosure access, saving you valuable maintenance and set-up time. The cover provides a vapor tight industrial seal and allows entry to internal components in less than five seconds.
3. Faster Wiring
Pre-wired and labeled terminal strip enables quick, convenient attachment of field wires.
4. Wide Variety of Switching & Communication
Switching options include dual module sensors and communication, Maxx-Guard proximity switches and mechanical switches. Continuous signal output is available in a 4 to 20 mA position transmitter.
5. Quick Set Cams are Easy to Adjust
Touch and Tune switch settings allow you to make adjustments in seconds without the use of tools.
6. Dual Shaft O-ring Seals Eliminate Corrosion
Top inner and bottom outer shaft o-rings seal the drive bushing from both external corrosives and internal contaminants that enter the enclosure.
7. Special drive bushing assures long cycle life
The oil impregnated brass bushing maintains smooth operation and eliminates the potential for shaft seizure due to actuator manufacturer shaft eccentricity.
8. Space Saving Visual Indication
Visual indicator offers excellent viewability without sacrificing accessibility or adding to space requirements. Indicators are also available with continuous percentage or three-way indication.
Eliminate Seal Fittings in Division 1 and 2 Areas
FMus ratings certify the Quartz QX series with proximity switches for use without seal fittings in all hazardous areas. By passing special pressure piling tests, the all aluminum enclosure was certified for this elite distinction. Now, a time-consuming procedure can be safely eliminated in division 1 and division 2 areas.
Consolidate Your Components and Minimize Costs
The Quartz design offers up to three conduit entries with extra wire terminations. By terminating solenoid valves manufacturer in the switch enclosure, significant savings are realized by eliminating a junction box, wiring, conduit materials and labor.
