General Characteristics:
The MP40 series microswitches are designed for snap-action changeovers with a simple switching action. They have a switching rating of 10A at 400VAC and are protected to IP40 for housing, IP00 for terminals, and IP20 for the cover. The class of protection is II, and they conform to EN61058-1:92 + A1:93 standards. The mechanical life is rated at 50 million operations, and they feature a beryllium copper leaf spring with self-cleaning contacts. The housing is made of PA6T/X reinforced with glass fiber, auto-extinguishing according to UL94 V-O, and certified for temperatures from -40°C to +130°C.

Models and Specifications:
Various models such as MP40-0, MP40-1A, MP40-5AL, and others are available, each with specific features like protection covers and actuators. The contact material is typically silver, with options for gold-plating. The connection type includes screw terminals and terminals with soldering lugs.

Installation and Fixing:
For lateral fixing, an insulating plate must be used between the microswitch and a metal surface. The tightening torque for fixing screws is specified as 0.5 Nm for M3 screws and 0.8 Nm for M3.5 screws.

Performance Parameters:
Key performance parameters include actuating force, release force, free position, operating position, over-travel, and differential movement. These parameters vary across different models, with specific values provided for each.

Special Designations:
Models with reduced contact gaps are indicated with a '1' after the series reference number, offering high repetitive switching precision and reduced switching ratings. Models with increased contact gaps are indicated with '-10', providing augmented differential travel.
