Honeywell Technologies HDLS Series Roller Lever Limit Switch, SPDT, IP65, IP66, IP67, Die Cast Zinc Housing, 600V ac,

This limit switch is a compact, side-mounted actuator device for detecting mechanical position changes in industrial systems. It uses a roller lever actuator and a snap-action contact arrangement to provide precise switching events in demanding environments. The enclosure is die-cast zinc with an epoxy finish and is rated for ingress protection in harsh conditions. Operating temperatures span low to high ranges to accommodate varied process requirements.

• 50,000,000 cycle mechanical life gives long operational endurance
• SPDT snap-action contact provides distinct single-pole changeover switching
• 10A switching current supports moderate-load circuit control
• 250V DC switching capability enables DC control circuit use
• IP65, IP66, IP67 enclosure protects against dust and water ingress

• Suitable for conveyor end-of-travel detection in factories
• Ideal for machine-tool limit sensing in production lines
• Used with motor starters for position-based shut-off
• Can be used for door-interlock status monitoring

It employs a roller lever actuator for reliable mechanical engagement.

The body is constructed from die-cast zinc with an epoxy coating.

It operates between -12°C and 121°C.

It meets CCC, CE, CSA, EN, IEC, RoHS and UL standards.

It is designed for side-orientation mounting to align the roller lever with moving parts.

UL, CSA.

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."
