SICK i110-E0253 Safety Lock with Power-to-Lock Mechanism
SICK i110-E0253 safety lock with power-to-lock mechanism is an electro-mechanical safety locking device designed to keep machine guards and protective doors securely locked until hazardous motion has completely stopped. It addresses the critical need to prevent unintended access to dangerous machine areas during operation or run-down. With a high locking force and clearly defined monitoring contacts, this model supports compliance with modern machine safety standards while maintaining reliable operation in demanding industrial environments. It is well suited for equipment where controlled access, operator protection, and process safety are mandatory.
The SICK i110-E0253 safety lock provides dependable guard locking by using a power-to-lock principle that holds doors closed during machine operation. Its electro-mechanical contact design delivers precise door and lock status signals to the safety control system, enabling predictable shutdown behavior and clear diagnostics. The rugged housing, metal actuator interface, and high ingress protection rating allow stable performance in dusty, humid, or vibration-prone areas. For machine builders and plant operators, this results in improved safety integrity, reduced unplanned stops, and consistent protection across repetitive production cycles.
Why SICK i110-E0253?
SICK i110-E0253 is chosen when machine safety must be both uncompromising and dependable. Its power-to-lock design ensures guards remain firmly secured during operation, while robust electro-mechanical contacts provide stable, predictable feedback to the safety system. Built for industrial environments, it combines high locking force, mechanical durability, and consistent performance, making it a trusted solution for machinery where safety, uptime, and long service life are equally critical.
What problem does it solve?
The SICK i110-E0253 solves the risk of accidental or premature access to hazardous machine areas. In many machines, doors may be opened before motion or energy has fully dissipated, creating serious safety hazards. This safety lock prevents that scenario by physically holding guards closed until safe conditions are reached, ensuring operators are protected and machinery complies with strict safety requirements without sacrificing operational efficiency.

The Applications
1. Reliable Safety Control in High-Speed Packaging Lines
High-speed packaging machines contain rapidly moving components such as sealing jaws, cutters, and transport belts that continue to move briefly after a stop command. The SICK i110-E0253 safety lock is used to keep protective doors securely closed until all hazardous motion has fully stopped. Its power-to-lock design prevents doors from being opened during operation, even when vibration or repeated impacts occur. The strong locking force resists forced entry, while the monitoring contacts deliver accurate status signals to the safety controller. This improves operator protection and reduces unnecessary downtime caused by premature door opening.
2. Controlled Access for Robotic Assembly Cells
Robotic assembly cells require frequent access for setup, tool changes, and maintenance, but uncontrolled entry can expose operators to moving robots and actuators. The SICK i110-E0253 is applied to safety doors to ensure access is only possible when the system is in a safe state. Its electro-mechanical contacts provide dependable feedback, allowing the safety logic to confirm both door position and lock status. Flexible actuation directions simplify installation on different door types. This approach improves safety consistency while supporting efficient workflow during routine adjustments and production changeovers.
3. Protection at Conveyor and Transfer Point Guarding
Conveyor systems often include transfer points where pinch zones and rotating elements create significant hazards. The SICK i110-E0253 safety lock is installed on access panels and service doors to prevent opening while conveyors are running. Its high locking force tolerates repeated mechanical stress common in material handling environments. The sealed housing supports reliable operation in dusty areas typically found in logistics and manufacturing plants. By ensuring access is only possible after movement has stopped, the safety lock helps reduce maintenance-related injuries and supports continuous system availability.
4. Safe Door Locking on CNC and Machining Centers
Machining centers and CNC equipment involve high-speed spindles and moving axes that remain dangerous even after a stop command. The SICK i110-E0253 is used to keep machine doors locked until rotation and motion have fully ceased. Its power-to-lock mechanism maintains secure closure during machining cycles, while monitoring contacts integrate with the machine safety system to control restart conditions. This setup enhances operator confidence, supports regulatory compliance, and allows machine builders to balance high productivity with dependable personnel protection.
