SMC Vacuum Switch with 1/8 in Male R Thread Port, NPN and PNP Switch Output, 100V AC, Height 15mm ZSM1-121L

SMC ZSM1-121L Vacuum Switch is a compact and highly reliable reed type vacuum sensor designed for pneumatic applications requiring accurate vacuum level monitoring within the range of -80 kPa to -27 kPa. The switch features a male R thread connection port of 1/8 inch size, suitable for air and gas media.

Operable in a voltage range of 100 V AC with a maximum current consumption of 17 mA, this device supports both NPN and PNP output switch types, ensuring compatibility with various control systems. It provides a feedback signal when the vacuum level reaches the preset threshold, allowing confirmation that a component has been successfully picked or vacuum level has been achieved.

This vacuum switch operates reliably in temperature conditions ranging from -5°C to 60°C, making it suitable for industrial, laboratory, HVAC, manufacturing, and pneumatic automation use cases. The built-in LED indicator gives immediate visual feedback on vacuum presence or switch status, facilitating troubleshooting and operational monitoring.

The switch's reed design offers repeatability of ±10% or less, ensuring precise detection over prolonged use. It has no hazardous area certifications or special approvals but meets standard industrial requirements for vacuum sensing applications.

Suitable for installation in compact pneumatic systems where height clearance is limited, the switch's height of 15 mm contributes to its ease of integration. It is a dependable component in vacuum circuits used in automation for pick-and-place equipment, vacuum generators, and pneumatic controls.

Equipped with NPN and PNP switch outputs for versatile electrical interfacing. Operates at 100 V AC voltage with low current consumption of 17 mA. Port size is 1/8 inch with male R thread standard connection. Vacuum pressure sensing range allows for maximum operating pressure up to -27 kPa and minimum pressure of -80 kPa.

Suitable for air and gas media with a pressure type designed specifically for vacuum applications. Features an LED indicator to provide visual status of vacuum detection. Operates reliably within a temperature range of -5˚C to 60˚C.

Compact height of 15 mm making integration into systems efficient. Reed type vacuum switch with series designation ZS providing high repeatability and stability.
