Honeywell Series SX Micro Switch, 1.39N Operating Force, 250V Contact AC Voltage - 21SX39-T
This micro switch is a Compact electromechanical switch designed for precise switching in control and sensing assemblies within industrial environments. It delivers single-pole changeover switching suitable for signal routing and load control, with a pin plunger actuator that provides direct mechanical actuation for limit detection and user-interface inputs.
Features and Benefits:
• SPCO contact arrangement for versatile circuit switching
• 250V AC contact rating supports mains-level applications
• 7A switching current enables moderate load control
• 1.39N actuation force for consistent tactile response
• Phenolic housing offers electrical insulation and dimensional stability
• Mechanical endurance to 10 million operations for long service life
• 250V AC contact rating supports mains-level applications
• 7A switching current enables moderate load control
• 1.39N actuation force for consistent tactile response
• Phenolic housing offers electrical insulation and dimensional stability
• Mechanical endurance to 10 million operations for long service life
Applications
• Suitable for end-of-travel detection in automation equipment
