Honeywell HDLS Series Limit Switch, 121°C Maximum Operating Temperature, IP65, IP66, IP67 - LSYAB6B
This limit switch is a mechanically actuated control device designed for position sensing and end-of-travel detection in industrial systems. It employs a plunger actuator and a snap‑action contact set to provide Rapid changeover signalling. The unit is intended for side mounting in machinery and offers a robust enclosure suitable for wet and dusty environments.
Features and Benefits:
• Snap‑action SPDT contact provides quick, definitive switching response
• Rated for 50,000,000 mechanical cycles for extended operational life
• Operates from −40°C to 121°C for wide thermal tolerance
• Die‑cast zinc housing affords strong physical protection
• Screw terminals deliver secure, field‑serviceable connections
• 0.5in to 14 NPT conduit entry enables standardised cable access
• Rated for 50,000,000 mechanical cycles for extended operational life
• Operates from −40°C to 121°C for wide thermal tolerance
• Die‑cast zinc housing affords strong physical protection
• Screw terminals deliver secure, field‑serviceable connections
• 0.5in to 14 NPT conduit entry enables standardised cable access
Applications
• Suitable for conveyor end‑of‑travel detection in manufacturing lines
• Ideal for limit sensing on automated packaging equipment
• Used for position monitoring in industrial valves and actuators
• Can be used for machine safety interlocks in production facilities
• Ideal for limit sensing on automated packaging equipment
• Used for position monitoring in industrial valves and actuators
• Can be used for machine safety interlocks in production facilities
What contact arrangement does it provide for control circuits?
It uses a single‑pole double‑throw contact configuration with snap‑action behaviour to switch between normally closed and normally open circuits.
How is the device mounted and oriented on equipment?
The unit is designed for side mounting which facilitates installation in confined spaces and aligns the plunger with lateral actuator surfaces.
What environmental protection does the enclosure offer?
The housing meets ingress protection levels that cover dust and water resistance suitable for demanding industrial atmospheres.
Which materials and Terminal type are used for field wiring and durability?
The enclosure is constructed from die‑cast zinc and incorporates screw‑type terminals for reliable electrical connections during maintenance.
What certifications support its use in regulated installations?
It carries recognised approvals from multiple standards bodies applicable to commercial industrial components.
Approvals
UL, CSA.
Standards
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."
