Siemens 3SE51121QV10

The Siemens 3SE51121QV10 is a safety position switch designed with a durable metal enclosure and comes with a separate actuator for enhanced safety applications. This device features a 40 mm connection and includes one slow-action contact configured as 1 normally open (NO) and 2 normally closed (NC) contacts. It is equipped with two indicator LEDs, yellow and green, which operate at 24 V DC to provide clear status feedback. The switch supports activation from five different approach directions, offering flexibility in installation. To function correctly, it requires the matching separate actuator, model 3SE5000-0AV0, which must be ordered alongside the switch. This Siemens position switch, available through BSP Automation, is a reliable choice for integrating safety monitoring into automated systems.
