Siemens 3SE5 Series Solenoid Interlock Switch, Power to Unlock, 24V DC, 3.5W, Metal Housing, IP66/IP67 3SE5312-0SD11

Siemens 3SE5312-0SD11 Solenoid Interlock Switch from the 3SE5 Series is engineered for workplace safety by controlling access to hazardous zones via power to unlock actuation. The switch monitors machine guard doors preventing accidental access while dangerous conditions persist. This model includes a standard coded actuator and a powerful 2600N locking force ensuring secure locking until safe conditions are confirmed.

The metal housing provides high durability and an IP66/IP67 rating meaning it is protected from dust and water ingress, suitable for industrial environments exposed to liquids. With screw-type terminals and standardized M20 conduit entry, installation is efficient and compatible with various electrical setups.

The switch features one normally open (NO) safety contact and one auxiliary contact to support control and signaling functions. It operates on a 24V DC supply with low power consumption at 3.5W, making it energy efficient for continuous operation.

Engineered for harsh industrial conditions, it endures vibration up to 5G and shock forces up to 30G. It operates reliably across a broad temperature range from -25°C to +60°C, providing confidence in diverse environments from manufacturing floors to automated assembly lines.

Certification by VDE, UL, and CSA standards ensures compliance with international safety and performance requirements. The compact design with dimensions of 159mm depth, 54mm length, and 43.8mm width fits easily in constrained spaces.

Ideal for industrial, automation, safety interlock, manufacturing, and machinery applications, this solenoid interlock switch enhances machine guarding systems and personnel protection with reliable access control.

The actuator is included with standard coded type for secure operation. Features 1 NO safety contact and 1 auxiliary contact for control circuit integration. Equipped with M20 conduit entry and screw terminal type for easy installation.

Metal housing with IP66 and IP67 ratings offers robust protection against dust and water. Operational at 24V DC supply voltage with a power consumption of 3.5W. Designed to withstand vibration forces up to 5G and shocks up to 30G for heavy industrial use.

Wide operational temperature range from -25°C to +60°C for demanding environments. Standards and approvals include VDE, UL, and CSA ensuring compliance and safety. Dimensions are 159mm depth, 54mm length, and 43.8mm width, suitable for compact spaces.
