Honeywell Technologies HDLS Series Roller Lever Limit Switch, SPDT, IP65, IP66, IP67, Stainless Steel Housing, 250V, 10A

This limit switch is a Compact mechanical position sensor designed for industrial control and automation environments. It provides a toggled electrical output when actuated by linear or rotary motion via a roller lever, and is constructed for use where ingress protection and robust switching behaviour are required.

• Roller lever actuator delivers precise mechanical actuation and repeatability
• Single-pole double-throw contact offers flexible circuit switching
• Snap-action contacts ensure fast transition and reduced contact bounce
• Stainless-steel housing resists corrosion in harsh surroundings
• IP67 enclosure rating allows operation in wet or dusty locations
• Mechanical durability rated to 10 million cycles for long service life

• Suitable for conveyor end-of-travel detection in material-handling systems
• Ideal for machine-tool limit sensing in metalworking equipment
• Used with automated packaging lines for position verification
• Can be used for safety interlocks on industrial doors and guards
• Used for actuator end-stop detection in valve assemblies

Termination is via screw terminals that accept standard industrial conductors for secure connections.

The device can operate at temperatures down to −12°C and up to 121°C without impairing switching function.

A 20mm conduit entry is provided to accommodate standard conduit fittings for protected cable routing.

It is designed for side mounting to align the actuator with motion axes in confined assemblies.

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."
