Honeywell Technologies HDLS Series Coil Spring Limit Switch, SPDT, IP67, IP66, IP65, Die Cast Zinc Epoxy Coated Housing,

This limit switch is a Compact industrial device designed to detect and interrupt mechanical movement within automated systems. Built for vertical mounting, it provides electrical switching for control circuits in demanding environments and suits a range of industrial applications where reliable position sensing and circuit changeover are required.

• SPDT contact offers selectable changeover switching for control circuits
• 8A switching current supports moderate power loads
• 600V AC and 250V DC ratings enable AC and DC circuit compatibility
• Die cast zinc housing provides robust protective enclosure
• Ingress protection to IP67 preserves operation in wet or dusty conditions
• Mechanical life rated at 50 million cycles ensures extended operational endurance

• Suitable for actuation detection on conveyor systems
• Ideal for limit sensing in packaging machinery
• Used with motor starters for end-of-travel shutdowns
• Can be used for position feedback in assembly robots
• Used for safety interlocks in heavy equipment installations

It uses a 12.7mm conduit entry to accommodate common industrial cable glands and threaded conduit fittings.

It is rated to function between -12°C and 93°C for typical industrial ambient conditions.

It carries IEC, RoHS, UL, CSA, CE, EN and CCC approvals for compliance in multiple regulatory regions.

The device is designed for vertical mounting to ensure intended actuator performance and repeatable switching.

A coil-spring actuator provides the mechanical displacement required to operate the contacts and reset reliably.

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."
