SMC Vacuum Switch -80 kPa to -27 kPa, Solid State Output, 10mA, 1/8 in Port, 100V AC, ZSM1-021L

The SMC ZSM1-021L Vacuum Switch is an industrial-grade sensing device designed for precise monitoring of vacuum pressure inside pneumatic systems. With a sensing range from -80 kPa to -27 kPa, it responds to changes in vacuum to trigger solid-state output signals that can be used for automated process control or safety interlocks. The switch features a solid state output with a voltage range of 10 to 26 V DC, making it compatible with diverse control equipment and offering enhanced reliability compared to mechanical contacts.

Integrated LED indicators provide clear status visibility, while repeatability within +/-10% ensures consistent detection of vacuum levels. Designed for connection via an R1/8 threaded port, the device is easily installed into pneumatic lines or interfaces, including compatibility with multi-stage vacuum pump systems.

With a current rating of 10mA and operation on 100V AC, this vacuum switch is engineered for efficient performance in both laboratory and industrial environments. It accommodates a compact footprint with a width of 15 mm, minimizing installation space requirements and supporting versatile deployment options.

Constructed to support a temperature range from -5°C to 60°C, the ZSM1-021L operates safely amidst demanding environmental conditions. Its suitability for both gas and air media extends its applicability across manufacturing, packaging, handling, and automation sectors.

The integrated solid state technology, hazardous area compliance, and high repeatability make it an excellent choice for users seeking reliable vacuum monitoring. Typical uses include robotic pick-and-place systems, material handling, assembly lines, and laboratory vacuum applications requiring precise feedback and automation integration.
