KBB2S02N Lovato METAL TOP ROLLER PLUNGER 2NC LEN 1/2NPT

Why Choose the Lovato KBB2S02N Metal Top Roller Plunger Limit Switch?

The Lovato KBB2S02N is a compact industrial top roller plunger limit switch designed for reliable mechanical position detection in machinery and automation systems. As part of the Lovato K series limit switch range, it combines a narrow plastic body with a durable metal roller plunger actuator and two normally closed contacts for dependable machine control and position monitoring.

The KBB2S02N features a 2NC slow-action contact configuration, making it suitable for applications requiring two normally closed circuits to change state when the actuator is operated. Its top roller push plunger is designed for repeated mechanical actuation by cams, slides and other moving machine components, while the roller helps reduce sliding friction at the point of contact.

Designed around the EN 50047 compact limit switch format, the KBB2S02N provides convenient integration into industrial equipment where installation space is limited. This variant incorporates a 1/2 NPT cable entry, making it suitable for installations using compatible threaded conduit and cable-entry systems.

Key Advantages

• Compact industrial limit switch for position and end-of-travel detection.
• Metal top roller plunger provides robust mechanical actuation.
• 2 normally closed (2NC) contacts for control, monitoring and interlocking functions.
• Slow-action switching mechanism provides defined contact operation through actuator travel.
• Narrow plastic body provides a compact installation footprint.
• 1/2 NPT cable entry for connection to compatible conduit and cable systems.
• EN 50047 format supports standardised installation in industrial machinery.
• Modular K series construction is designed for straightforward installation, wiring and adjustment.

Reliable Position Detection for Industrial Machinery

Limit switches such as the Lovato KBB2S02N convert the physical movement of machinery into an electrical switching signal. When a moving component contacts the top roller plunger, the actuator travels and changes the state of the internal contacts, enabling the control system to detect position, confirm movement or initiate another machine function.

The 2NC slow-action contact arrangement provides two normally closed circuits from a single mechanical actuator. Combined with the compact EN 50047 body, modular operating head and metal roller plunger, this makes the KBB2S02N well suited to machine sequencing, position confirmation, travel limitation and industrial interlocking applications.

Typical Applications

• Machine end-of-travel detection.
• Industrial position sensing and monitoring.
• Conveyors and material handling equipment.
• Packaging and production machinery.
• Machine tools and automated equipment.
• Moving machine assemblies and mechanical mechanisms.
• Mechanical sequencing and interlocking systems.
• OEM machinery and industrial automation systems.
