Product Description

The Siemens SIRIUS 3SE5 Series Plunger Limit Switch model 3SE5242-0HC05 is engineered for demanding industrial automation environments that require durable position sensing with high electrical and mechanical performance. Featuring 1 normally open (NO) and 1 normally closed (NC) snap action contacts, this switch offers reliable safety interlock and monitoring in various machinery and conveyor systems.

The switch enclosure achieves IP67 and IP66 protection, allowing installation in wet, dusty, and harsh environments, while the robust plastic housing mitigates corrosion and makes the device lightweight for easy integration. The plunger actuator head ensures direct and precise detection of moving mechanical components, triggering when a defined position is reached.

Supporting a maximum switching current of 4A, the SIRIUS 3SE5 Plunger Limit Switch is suitable for both control circuit and low power industrial applications. It is designed for universal mounting, enabling flexible installation with M20 x 1.5 conduit entry for secure wiring connections. The mechanical life expectancy of 15 million operation cycles attests to its resilience in high-cycle and continuous-use settings.

The switch operates reliably across a wide temperature range from -25°C to 85°C, suitable for climates from refrigerated storage to high-heat manufacturing. The compact dimensions (60.7mm x 55.5mm x 33mm) make it well-suited for confined panel spaces, and the actuator head can be replaced and rotated in 22.5° increments for maintenance flexibility. Integrated chlorinated rubber diaphragm contributes to functional safety even in cold and aggressive environments.

Siemens SIRIUS 3SE5 limit switches are internationally approved to IEC, EN, UL, CE, CSA, CCC, RoHS, and EAC standards, supporting compliance for exports and regulated markets. Common industrial use cases include machine guarding, conveyor system position feedback, packaging line automation, industrial robots, and material handling equipment.
