Datasheet
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
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.
• Silver or gold-plated contacts
• Plug-in and non plug-in bodies have identical operating
characteristics and are dimensionally interchangeable
POTENTIAL APPLICATIONS
• Machine tools
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.
• Automotive machine tools
• Material handling
• Outdoor electromechanical structures
• Balers/compactors
• Conveyors
• Food and beverage
• Power plants
• Off-road equipment
• Agricultural equipment
• Valves
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
• Transportation hubs
