From Honeywell, the HDLS series are heavy duty limit switches. They have a robust construction that is able to handle the most heavy duty applications within harsh environments. They can be used in environments where they are subject to vibration, shock and intense temperatures (both high and low). Suitable for use indoors or outdoors, these limit switches can also withstand dust, coolants and water (whether it’s splashing water or hose directed).

The base of the limit switch is either prewired, has a conduit connection or features a connector. It also contains all of the wiring. You can easily mount the switching component and operating head to the base using only two screws.

With an outstanding mechanical life span of up to 50 million actuation cycles, these limit switches offer incredible operational reliability and repeatability.
• With a modular construction, HDLS limit switches offer numerous actuator styles, circuitry and operating head options. You will find a heavy duty limit to meet your application within this series.
• HDLS limit switches are constructed from corrosion resistant zinc which is epoxy coated and phosphate treated. Optional fluorosilicone and fluorocarbon seals are available (dependent on model).
• HLDS limit switches have twin shaft seals that provide extra protection from harsh environments. A diaphragm seal also offers an additional degree of protection.
• With a unique teller tab as standard, you can easily tell that the limit switch has the proper torque required for you application. When it cannot be moved any further, you can be assured that the lever is tight enough to prevent any slippage.
• HDLS switches can be mounted from either the front or back of the unit. Each model features four mounting holes; two through holes for front mounting and two tapped holes at the back for rear mounting.
• This series of limit switches feature dual bearings, which increases their mechanical lifespan.
• Within the main body of the switch you are able to easily identify which terminals are used as grounding terminals. This makes it easy for you to comply with regulatory standards.
• HDLS limit switches feature double break contacts with the same polarity on each pole.
