In addition, these Miniature Limit Switches are built to withstand demanding industrial environments, supporting a rated switching current of 5A at 250VAC, and delivering an impressive 300,000 electrical switching cycles at full load. With a variety of actuator configurations and IP67 ingress protection, LS-V Series switches combine flexibility with rugged performance.

Key Features of LS-V Series Miniature Limit Switches

The LS-V lineup incorporates several design advancements that enhance reliability, longevity, and ease of use. Below are the major features that define this series.

Compact Design With Enhanced Wiring Space

Although categorized as Miniature Limit Switches, the LS-V series has been thoughtfully crafted to offer generous wiring space. The two-part housing system—consisting of a zinc die-cast base and a UL94-V0 flame-retardant thermoplastic cover—allows users to perform wiring or field inspection without difficulty.

This compact yet user-friendly design makes the switches suitable for small industrial machines, robotic equipment, packaging units, conveyor systems, and other automation solutions.

High Electrical and Mechanical Durability

Durability is one of the strongest attributes of the LS-V Series Miniature Limit Switches. As per the specifications:

• Electrical Life: 300,000 operations at full load
• Mechanical Life: 10 million operations
• Electrical Rating: 5A at 250VAC (AC-15 duty), 0.4A at 125VDC (DC-13 duty)

These qualities ensure that LS-V switches offer long-lasting performance, even in repetitive operation environments where continuous switching is required.

Strong Environmental Protection (IP67)

The LS-V switches are designed for IP67 protection, making them resistant to:

• Dust intrusion
• Water jets or splashes
• Common industrial contaminants

This rating makes the Miniature Limit Switches suitable for applications in machinery exposed to oils, moisture, or particulate matter.

Snap-Action Crossbar Mechanism

The LS-V switches utilize a 1NO + 1NC snap-acting mechanism with a crossbar design that ensures reliable switching with minimal contact bounce. This improves accuracy, reduces wear, and enhances longevity.

Modular Actuator Head

One of the most user-friendly features of the LS-V series is its modular actuator head, which can be rotated in 90° increments simply by loosening the mounting screws. This flexibility ensures easy adjustment on-site, allowing the switch to be configured for different installation orientations or application requirements.

Actuator Options in LS-V Series Miniature Limit Switches

Different industrial applications require specific actuator mechanisms. The LS-V series offers five actuator variations, making these Miniature Limit Switches adaptable to a wide range of tasks.

Actuator Types and Their Models

Each actuator type serves a different mechanical movement requirement—linear, rotational, or multi-directional making the LS-V range suitable for automation systems, conveyor lines, mechanical position sensing, and safety circuits.
