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

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
