Siemens 3SE52500PC058K Position Switch – Plastic Enclosure, Metal Plunger, 2 NO/1 NC

The Siemens 3SE52500PC058K is a position switch with a plastic enclosure and metal plunger, designed for position monitoring and mechanical limit detection in industrial machinery and automation systems. It features an open-type 30 mm enclosure, 2 NO and 1 NC slow-action contacts, and an IP10 degree of protection.

This position switch is suitable for applications where the movement or position of a machine component needs to be detected through direct mechanical actuation. The metal plunger provides a straightforward mechanical sensing interface, while the combination of normally open and normally closed contacts offers flexibility for control, signaling, and monitoring circuits.

What Is Siemens 3SE52500PC058K Used For?

The Siemens 3SE52500PC058K position switch is used to detect the position or movement of mechanical machine components.

Position switches are commonly installed at specific points on machinery so that the movement of a mechanical part can operate the switch. The resulting contact signal can then be used by a control system for functions such as machine sequencing, position confirmation, limit detection, or interlocking.

The metal plunger is mechanically actuated when the monitored machine component reaches the defined position. The switch's slow-action contact mechanism changes the contact state according to the mechanical movement.

2 NO + 1 NC Contact Configuration

The 3SE52500PC058K provides 2 normally open (NO) and 1 normally closed (NC) contacts.

This contact arrangement can provide multiple switching possibilities within a machine-control circuit.

The contacts can be used for applications such as:

• Position indication
• Machine sequencing
• Limit detection
• Control interlocking
• Auxiliary signaling
• PLC input signals
• Machine-status monitoring

The exact electrical application should be determined according to the control-system design and contact ratings.

Slow-Action Contact Mechanism

The switch uses slow-action contacts, where the contact movement follows the mechanical movement of the actuating plunger.

This type of mechanism is commonly used for mechanical position monitoring applications where a machine component directly operates the switch.

The actual switching behavior and contact arrangement should be considered when designing the associated control circuit.

Metal Plunger for Mechanical Detection

The metal plunger provides a direct mechanical actuation method.

When the monitored machine component reaches the switch's actuation point, it presses the plunger and changes the state of the internal contacts.

This makes the switch suitable for detecting:

• End positions
• Mechanical travel limits
• Component presence
• Machine movement
• Door or cover positions
• Mechanical sequencing points

The plunger should be correctly aligned with the moving machine component to prevent unnecessary mechanical stress and premature wear.

Plastic Enclosure and Open-Type Construction

The 3SE52500PC058K uses a plastic enclosure with an open-type construction.

This design is intended for suitable industrial installations where the surrounding equipment provides the necessary environmental protection.

Because the specified protection rating is IP10, the device should not be treated as a sealed position switch for exposed or wet environments. The installation location should provide appropriate protection against environmental conditions and accidental contact.

IP10 Protection

The position switch is specified with an IP10 degree of protection.

This makes proper installation particularly important. The device should be installed in a suitable control or machine environment where it is protected from conditions outside its specified protection capability.

For applications involving dust, water, oil, washdown or harsh environmental exposure, a position switch with a more suitable protection rating should be selected.

Typical Applications

The Siemens 3SE52500PC058K position switch can be considered for appropriately designed applications including:

• Industrial machinery
• Machine position monitoring
• Mechanical limit detection
• Production machinery
• Conveyor systems
• Packaging equipment
• Material-handling systems
• Machine tools
• Manufacturing equipment
• Automated machinery
• Mechanical interlocking
• Machine sequencing
• Control-panel input circuits

Position Monitoring in Automation Systems

Position switches provide a simple and reliable way to convert mechanical movement into an electrical control signal.

The 3SE52500PC058K can be integrated into an automation system where a machine component needs to provide a discrete position signal.

For example, a machine's moving assembly may actuate the metal plunger at the end of its travel. The resulting contact change can then be monitored by a PLC or control circuit to confirm that the mechanism has reached the required position.

The suitability of the switch depends on the mechanical arrangement, switching frequency, environmental conditions, and electrical requirements of the application.

Benefits for OEM Machine Builders

For OEM machine manufacturers, the 3SE52500PC058K provides a compact mechanical position-monitoring solution.

Its 2 NO + 1 NC contact configuration provides flexibility for connecting multiple control or signaling circuits, while the metal plunger allows straightforward mechanical actuation.

It can be useful in machine designs where direct mechanical position sensing is preferred over electronic proximity sensing.

Benefits for Panel Builders and Maintenance Teams

The position switch can be used as part of machine-control and limit-detection circuits.

Its conventional mechanical switching principle makes it suitable for applications where a simple contact-based position signal is required.

For replacement applications, users should verify the complete Siemens order number, actuator type, contact configuration, enclosure design, protection rating, and mounting arrangement before ordering.
