Technical Specifications
Contact type: SPDT snap-action. Contact rating: 15A @ 250V AC, 0.5A @ 250V DC. Actuator type: top push plunger. Enclosure type: die-cast metal. Protection rating: IP67. Operating temperature range: -40°C to +120°C. Electrical life: 1,000,000 operations minimum. Mechanical life: 10,000,000 operations minimum.
Functional Features
Heavy-duty die-cast metal housing withstands harsh industrial environments. Snap-action contact mechanism provides quick make-break operation. Positive opening contacts ensure reliable disconnection. IP67 sealing resists water, dust and oil. Multiple mounting positions for flexible installation. Silver alloy contacts for long electrical life.
Application Scenarios
It is used for end-of-travel detection on conveyors, machine tool limit detection, hoist and crane travel limits, material handling equipment position sensing, and industrial safety interlock systems.
Performance Parameters
Contact rating: 15A @ 250V AC. Actuation force: 2.5N typical. Contact bounce: <1ms. Operating temperature range: -40°C to +120°C. Vibration resistance: 10G @ 10Hz to 500Hz. Shock resistance: 30G.
Material Composition
Housing: die-cast zinc alloy with epoxy powder coat. Contacts: silver alloy. Actuator: hardened steel. Seal: nitrile rubber. Terminals: tin-plated copper.
Structural Characteristics
It features a rectangular metal body, top push plunger actuator, side cable entry, mounting feet, and screw terminal connections.
Working Principle
When the plunger is depressed by the moving target, the internal snap mechanism rapidly transfers the contact from normally closed to normally open position. When force is removed, the return spring resets the contacts to the normal state.
Installation Requirements
Mount on machine frame with mounting bolts. Align plunger with target travel path. Set overtravel per specification. Connect wiring per contact rating. Seal cable entry gland for IP67 rating.
