Honeywell Series CH Limit Switch, 28V AC Switching Voltage, 4A Switching Current - 1CH28-12
This limit switch is a Compact mechanical actuator designed to detect position changes in industrial systems. Its plunger actuator provides straightforward contact actuation for control circuits, while a stainless-steel enclosure suits demanding operational environments. The device connects via a cable Terminal and is configured for single-pole double-throw switching, making it suitable for integration into control panels and automated assemblies.
Features and Benefits:
• SPDT contact arrangement enables flexible circuit switching
• Switching rating of 28V AC supports low-voltage control circuits
• 4A switching current handles moderate load currents
• Stainless-steel housing resists corrosive conditions
• Side mounting orientation facilitates confined-space installation
• Compact overall length and depth of 2.595in supports tight layouts
• Switching rating of 28V AC supports low-voltage control circuits
• 4A switching current handles moderate load currents
• Stainless-steel housing resists corrosive conditions
• Side mounting orientation facilitates confined-space installation
• Compact overall length and depth of 2.595in supports tight layouts
Applications
• Suitable for position sensing on conveyor end-stops
• Ideal for actuation feedback in automated machinery
• Used with control relays in assembly-line safety interlocks
• Can be used for door-closure detection in industrial cabinets

How is the device intended to be mounted?
It is designed for side-orientated installation, allowing the plunger to be positioned where linear movement occurs and conserving panel depth.
What type of wiring termination does it use?
The switch is supplied with a cable-style Terminal for direct cable connection, simplifying wiring in retrofit or new installations.
Which approvals govern its use in electrical systems?
It meets CSA and UL standards for general industrial electrical applications.
Is the construction suitable for corrosive work environments?
The body is MADE from stainless steel, providing enhanced resistance to chemical and environmental exposure.
What actuator response is provided for mechanical interfaces?
The plunger actuator gives positive mechanical engagement, offering repeatable actuation for position-detection tasks.
Approvals
UL, CSA.
