This limit switch from Honeywell is a hardwearing option for use in harsh environments. Thanks to its epoxy-coated, die-cast zinc housing, this sensory device offers reliable impact and corrosion resistance, so it can stand up to harsh environmental conditions. It's also effectively sealed and has an IP67 (ingress protection) rating, so it's resistant to dust and temporary submersion in water for use in damp or dusty environments.
This general-purpose limit switch has a compact design that makes it suitable for use in confined spaces. It's commonly found in production lines and factories.

• Double break contacts give you control of two circuits with one switch for added versatility
• Wide operating temperature range of -29°C to +120°C for use in harsh environments
• Maximum current consumption of 10A for optimal energy efficiency
• Snap-action mechanism for fast response times

• Valve actuation
• Food and beverage production facilities
• Machine tooling equipment

An actuator is a device that's designed to convert an electrical signal into mechanical motion. It's an integral part of a limit switch like this one.
