Product Description

The NLL1MC Heavy Duty Limit Switch (Maintained Type, Precabled) is a durable and high-performance industrial switch designed for accurate position sensing and reliable control in automation systems. As part of the NL Snap Action Series, this switch ensures fast response, precise switching, and long operational life even under continuous-duty conditions.

This model features a maintained (latching) mechanism, where the contact position remains fixed after actuation until it is reset or actuated again. This makes it ideal for applications requiring a stable ON/OFF condition without continuous mechanical force, such as safety interlocks, machine control systems, and process automation.

The switch is equipped with a roller lever actuator, ensuring smooth and reliable actuation for both linear and rotary movements. Its compact 38mm body size allows easy installation in space-constrained industrial environments while maintaining high durability.

A key advantage of the NLL1MC is its precabled (pre-wired) design, which eliminates the need for manual wiring. This reduces installation time, minimizes wiring errors, and ensures a secure and consistent electrical connection, making it highly suitable for quick deployment and maintenance.

With a 1NO + 1NC contact configuration, the switch provides flexible control options for various automation applications.

Designed with an IP67 protection rating, the NLL1MC offers complete protection against dust and resistance to water ingress, ensuring reliable performance in harsh environments such as exposure to moisture, oil, dust, and vibration.
