This advanced switching capability makes the 0168 Series particularly valuable in control applications requiring sophisticated pressure monitoring with multiple control outputs or failsafe operation. The changeover functionality allows system designers to implement more complex control strategies without requiring additional pressure switches or external relay logic.

Precision Electrical Performance

The microswitch elements in the 0168 Series provide exceptional electrical performance that surpasses conventional pressure switch contacts:

• Precise switching with minimal differential

• Higher electrical ratings for direct load control

• True changeover (SPDT) contact functionality

• Extended electrical lifecycle performance

• Consistent operation throughout service life

These electrical performance advantages make the 0168 Series ideal for applications where switching precision directly impacts system control quality or where higher electrical requirements exceed the capabilities of standard pressure switch contacts.

Technical Performance

Reliable Pressure Monitoring

At its core, the 0168 Series utilizes SUCO's field-proven diaphragm sensing technology. The precision-engineered diaphragm element responds immediately to pressure changes while providing inherent resistance to system contamination that would compromise piston-type pressure switches. This design principle has demonstrated exceptional reliability across diverse industrial applications.

The pressure sensing capabilities include:

• Rapid response to pressure changes for timely system control

• Consistent repeatability for predictable operation

• Stable setpoint retention despite environmental challenges

• Excellent resistance to pressure spikes and hydraulic shock

These performance characteristics ensure reliable pressure monitoring throughout extended service periods, with the microswitch elements maintaining consistent electrical performance despite the challenging conditions typical of industrial applications.

Industrial-Grade Construction

The 0168 Series is built for industrial reality rather than laboratory conditions. Key construction features include:

• Robust housing designed for mechanical protection

• High-quality diaphragm elements for extended service life

• Premium microswitch components for switching reliability

• Protected electrical terminals for installation security

• Materials selected for industrial environment compatibility

This industrial-grade construction ensures reliable operation in challenging environments where lesser switches would experience premature failure or inconsistent performance. The resulting operational reliability translates directly to reduced maintenance requirements and improved system uptime.

Applications

Complex Control Systems

The 0168 Series excels in control system applications where advanced switching capabilities enable more sophisticated pressure monitoring and control functions. The microswitch changeover contacts allow implementation of dual-function control, where one pressure threshold can simultaneously activate one circuit while deactivating another without requiring external relays or additional pressure switches.

In manufacturing automation, process control, and equipment protection circuits, the 0168 Series provides switching versatility that simplifies control system design while reducing component count and potential failure points. This functional advantage makes the 0168 Series particularly valuable in complex control applications where simplified wiring and reduced component requirements provide significant design and reliability benefits.

Critical Equipment Protection

In applications where equipment protection depends on reliable pressure monitoring with failsafe capabilities, the 0168 Series provides the advanced switching functions needed for comprehensive protection strategies. The changeover contacts enable simultaneous alarm activation and equipment shutdown from a single pressure switch, ensuring coordinated protection response while simplifying system design.

The 0168 Series is particularly well-suited for critical equipment protection in applications where pressure anomalies require immediate, multi-function response to prevent damage or unsafe conditions. The microswitch reliability ensures consistent protection throughout extended service periods, with minimal risk of contact failure during critical protection events.

Process Control Applications

In process applications where pressure parameters directly impact product quality and system integrity, the 0168 Series provides the sophisticated switching capabilities needed for precise control implementation. The microswitch precision enables accurate pressure detection with minimal switching differential, contributing to tighter process control and improved product consistency.

The changeover functionality allows implementation of more sophisticated control strategies, including differential control, band control, or conditional operation based on pressure parameters. This switching versatility makes the 0168 Series particularly valuable in process applications requiring advanced control capabilities without introducing excessive complexity or additional components.
