MICRO SWITCH HeavyDuty Limit Switch

HDLS Series

DESCRIPTION

Honeywell’s MICRO SWITCH heavy-duty limit switches’

modular construction allows for a wide variety of actuator

styles, operating heads, and electrical circuitry options. The

plug-in versions greatly reduce downtime on production lines

with high actuation rates as replacement of the switch is

accomplished in seconds. The base receptacle contains all the

wiring and conduit connection while the switching component

with operating head easily assembles to the base and is

attached with two screws.

They are ideal for many applications with demanding indoor

and/or outdoor environments, where they may be subjected

to shock or vibration from equipment, temperature extremes,

dust, splashing water, coolant, and/or hose-directed water.

DIFFERENTIATION

• Sintered bronze bearing on 303 stainless steel operating

shaft for enhanced mechanical life (up to 50 million

actuation cycles) and operational reliability

• All-metal drive train for consistent operating characteristics,

even at high temperature. Lasts longer (without need for

frequent adjustment) than drive trains with plastic parts

• Exclusive teller tab ensures proper torque. When it cannot be

moved, the lever is tight enough to prevent slippage

VALUE TO CUSTOMERS

• NEMA 1, 3, 4, 4X, 6, 6P, 12, 13 and IP65/66/67

environmental sealing for demanding applications

• Industry-leading breadth-of-product offering: HDLS

standard, HDLS harsh-duty epoxy sealed, or the HDLS

stainless steel

• UL, CSA, CE, and CCC approvals for global use

• Conﬁgurable product platform for design versatility

• Large, existing installation base and channel allows for quick

delivery worldwide

FEATURES

• NEMA 1, 3, 4, 4X, 6, 6P, 12, 13 and IP65/66/67

environmental sealing

• NEMA/IP sealing features twin shaft seals for an extra

measure of protection

• Rugged, corrosion-resistant zinc head and body are

phosphate treated and epoxy coated

• Diaphragm seal between head and body provides an extra

measure of protection

• Multiple connectivity options for international applications

• Fluorosilicone seals available for low temperature

applications, and ﬂuorocarbon seals available for chemically

harsh environments and higher temperature applications

• Secure head-to-body retention with the head in any one of

four positions 90° apart

• Self-lifting pressure plate terminals saves wiring time

• Wide variety of actuators, switch options, and head styles

• Rotary actuated heads are ﬁeld adjustable for CW actuation,

CCW actuation, or both

• Silver or gold-plated contacts

• Plug-in and non plug-in bodies have identical operating

characteristics and are dimensionally interchangeable

POTENTIAL APPLICATIONS

• Machine tools

• Automotive machine tools

• Material handling

• Outdoor electromechanical structures

• Balers/compactors

• Conveyors

• Food and beverage

• Power plants

• Off-road equipment

• Agricultural equipment

• Valves

• Transportation hubs

MICRO SWITCH Heavy-Duty Limit Switch, HDLS Series SPECIAL APPLICATIONS High Capacity Limit Switch Features • High dc current ratings • 20 A rating at 120 Vac (single pole) • Plug-in or non-plug in • Positive retention lever arm • High resistance to seismic shock This series has a wide gap contact block that handles a higher make/break dc load. In addition, a special lever arm has a serrated shaft hole and a cap screw with locking nut for attaching the lever to the rotary shaft.
PAGE 36
MICRO SWITCH Heavy-Duty Limit Switch, HDLS Series SPECIAL APPLICATIONS Gravity Return Side Rotary Switches (LSS) Extra Low Torque Side Rotary Switches (LST) LSS1H gravity-return, side-rotary switches have no return spring mechanism. The weight of the actuating lever must provide the force to restore it to the free position. The 5 in-oz. max. operating torque is useful in conveyor applications since it enables operation by small or lightweight objects.
PAGE 37
MICRO SWITCH Heavy-Duty Limit Switch, HDLS Series ALSO AVAILABLE Fully potted MICRO SWITCH HDLS heavy-duty limit switches provide an extra degree of protection in harsh environments by sealing the basic switch cavity with epoxy. These switches are the same as the nonplug-in HDLS except that the entire switch cavity is filled with epoxy in addition to the conduit entrance. The fully potted HDLS switches are pre-leaded, with either cable or connectors.
