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

This limit switch is a mechanical device that provides reliable position detection in industrial systems. It uses a side-mounted rotary actuator and snap-action contacts to deliver repeatable switching for control and safety circuits. The enclosure is formed from epoxy-coated die-cast zinc to withstand industrial environments and the unit is suitable for side-orientated mounting where a compact, sealed actuator is required.

• DPDT contact arrangement delivers versatile circuit switching
• Snap action contact type provides fast, positive transition
• 50,000,000 cycle mechanical life ensures extended operational durability
• IP65 IP66 IP67 sealing allows use in harsh environments
• Operating range -12°C to 121°C supports high-temperature applications

• Suitable for conveyor end-of-travel detection in factories
• Used with hoist limit detection in material handling systems
• Ideal for actuator position feedback in automation panels
• Can be used for gate or barrier safety interlocks
• Suitable for outdoor control cabinets requiring sealed controls

It employs a double-pole double-throw contact layout to switch two circuits independently.

The housing is die-cast zinc with an epoxy coating to provide a protective barrier against environmental degradation.

It is designed for side mounting to accept a side rotary actuator and align with lateral motion.

It carries a range of certifications including CE, UL, CSA, IEC, EN, RoHS and CCC.

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."
