Honeywell Technologies HDLS Series Side Rotary Limit Switch, DPDT, IP67, IP66, IP65, Die Cast Zinc Epoxy Coated Housing,

This limit switch provides robust mechanical position sensing for industrial automation and control circuits. It is a side-actuated rotary device designed for mounting on the flank of equipment where reliable contact switching is required. The unit offers snap-action switching and is rated for common AC and DC voltages, making it suitable for integration with electrical and electronic control systems in demanding environments.

• DPDT snap-action contacts deliver versatile circuit control
• 10A switching current supports moderate power loads
• 600V AC and 250V DC ratings permit broad voltage use
• Die-cast zinc housing offers solid environmental protection
• IP65, IP66 and IP67 ingress ratings enable outdoor installation
• Mechanical life of 50 million cycles minimises replacement downtime

• Suitable for limit detection on conveyor and material-handling systems
• Ideal for interlock sensing in electrical switchgear assemblies
• Used with actuated valves for end-of-travel signalling in process plants
• Can be used for position feedback in industrial machine tools
• Suitable for safety and control circuits in packaging equipment

It is designed for side mounting so the rotary actuator operates from the flank of the host equipment.

The rotary actuator requires an operating force of 0.45 N·m to engage the switching mechanism.

The device is specified for use between -1°C and 121°C for normal operational environments.

The unit provides a conduit entry sized at 355.6mm to accommodate conduit or cable glands.

IP65, IP66, IP67
HDLS switches have a IP65, IP66 and IP67 rating. This means they are dust-tight and offer protection against water jets, heavy seas and the effects of immersion.


NEMA 1, 3, 4, 4X, 6, 6P, 12, 13
Type 1: Enclosures that meet Type 1 are for indoor use, and provide some limited protection for the enclosed equipment.
Type 3: Allows for indoor or outdoor use and provides a degree of protection against access to hazardous parts. The enclosures provide some protection from foreign objects (such as windblown dust) and the ingress of water (such as rain or snow). Enclosures that meet NEMA 3 offer protection against ice forming externally.
Type 4: Allows for indoor or outdoor use and provides a degree of protection against access to hazardous parts. The enclosures provide some protection from foreign objects (such as falling dirt and windblown dust) and the ingress of water (such as rain, snow or sleet alongside splashing water and hose directed water). Enclosures that meet NEMA 3 offer protection against ice forming externally.
Type 4X: Allows for indoor our outdoor use and provides some ptoection against windust dust and rain, corroision, splashing water and hose directed water.
Type 6: Allows for indoor or outdoor use and provides a degree of protection against access to hazardous parts. The enclosures provide some protection from foreign objects (such as falling dirt and windblown dust) and the ingress of water (such as rain, snow or sleet alongside splashing water and hose directed water). Enclosures that meet NEMA 4 offer protection against ice forming externally.
Type 6P: Allows for indoor or outdoor use and provides a degree of protection against access to hazardous parts. The enclosures provide some protection from solid objects (such as falling dirt and windblown dust) and the ingress of water (such as hose directed water). Enclosures that meet the NEMA 6P requirement also offer protection against water when being submerged at a limited depth.
Type 12: Limit switches that meet Type 12 requirements provide limited protection against dust, falling dirt and non-corrosive liquids.
Type 13: Enclosures that meet Type 13 are suited to harsh environments. Enclosures can be used indoors and provide protection against access to hazardous parts. They offer protection against solid objects such as falling dirt, windblown dirt, fibres and lint. They provide a level of protection from dripping and splashing water and other liquids such as spraying splashing and seepage of oil and non-corrosive coolants."
