Honeywell HDLS Series Side Rotary Limit Switch, DPDT, IP67, IP65, IP66, Die Cast Zinc Housing, 600V ac

This limit switch is a robust side-mounted electromechanical device designed to detect and interrupt motion in industrial systems. It operates via a side rotary actuator to provide reliable position sensing and switching in machinery and control panels. The unit is built for harsh environments and offers snap-action contact behaviour suitable for automation, electrical and mechanical applications.

• DPDT snap-action contacts deliver versatile circuit switching capability
• Rated switching AC voltage of 600V for high-voltage control applications
• Mechanical endurance of 50 million cycles for prolonged duty life
• Die-cast zinc housing resists impact in industrial settings
• IP67, IP65, IP66 ingress protection for wet and dusty environments
• Conduit entry sized at 19.05mm for standard cable gland fittings

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for limit sensing on heavy machinery with rotating shafts
• Used with control cabinets requiring high-voltage switching elements
• Can be used for safety interlocks in outdoor installations
• Used for position feedback in automated assembly equipment

The device is intended for side mounting, enabling Compact installation on equipment flanks and rotary shafts.

The unit provides double-throw switching which allows two independent circuits or changeover functions to be implemented from a single actuator movement.

The specified operating temperature range extends down to -12°C and up to 121°C to accommodate a variety of industrial ambient conditions.

It holds recognition to international and regional standards including UL, EN, IEC, RoHS, CCC, CE and CSA which support integration into certified systems.

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."
