COMITRONIC / BTI is a trusted provider of industrial safety solutions, delivering a wide range of products designed to protect personnel and machines in hazardous environments. Known for their innovation in non-contact safety switches and RFID technologies, COMITRONIC / BTI offers a full suite of safety interlock systems built to meet strict international safety requirements.
This category page contains their line-up of robust stainless steel switches engineered for durability in demanding applications. Whether protecting access points on dangerous machines or integrating into automated systems, COMITRONIC’s solutions are proven to enhance operational safety and reduce downtime.
These safety switches are essential components in risk reduction strategies, acting as the first line of defence against accidental machine start-ups or unauthorized access. With variants designed for harsh environments, cleanroom installations, and hazardous areas, COMITRONIC offers one of the most comprehensive safety switch portfolios on the market.
Key Technologies and Components
Electromagnetic Safety Lock Control
The electromagnetic safety lock control systems offered by COMITRONIC / BTI ensure secure locking of doors and guards during hazardous operations. These systems maintain controlled access and prevent accidental exposure to moving parts using reliable safety locking contacts.
Magnetic Locking and Mechanical Switches
Combining magnetic locking with reliable stainless steel mechanical switches, these devices provide layered protection. This redundancy increases safety and system reliability, especially in high-risk machinery setups.
Safety Relay and Safety Module Integration
All COMITRONIC solutions are compatible with industry-standard safety relays and safety modules. These components play a central role in emergency stop circuits and logic-based safety controls.
Some COMITRONIC systems also support double safety relay configurations, offering an extra layer of redundancy and fault tolerance. By using dual-channel monitoring, these relays ensure that even if one channel fails, the second maintains circuit integrity, thereby preventing unsafe conditions and complying with the highest performance level (PL e) requirements.
Auxiliary Output and Monitoring
Most devices include auxiliary output features for real-time monitoring of lock status, door position, and power states—allowing operators and controllers to respond quickly to any deviation from expected operation.
These auxiliary outputs serve as critical communication links between safety devices and supervisory systems. By providing status feedback for diagnostic purposes, they support proactive maintenance planning and quick fault identification. Whether used for triggering alarms, informing programmable controllers, or aiding machine logic decisions, COMITRONIC’s auxiliary outputs enhance overall visibility and response in safety-critical operations.
Position Control and Door Access Management
Integrated position control functionality ensures accurate detection of actuator alignment, while control for doors provides intelligent access solutions for automated systems. This dual capability improves both machine safety and operational efficiency.
COMITRONIC’s control for doors solutions are specifically designed to manage safe access to restricted or hazardous zones. Whether managing entry into robotic cells or safeguarding high-speed machinery, these systems offer real-time control and feedback for door status. By integrating electronic interlocks with access permissions, they prevent unauthorized entry, reduce the risk of injury, and support regulatory compliance in safety-critical applications.
Static Safety Outputs for Reliability
Devices with static safety outputs deliver stable, noise-resistant signaling to safety controllers. This reduces false triggers and enhances reliability in electrically noisy environments.
Electronic Sensors and Detection
Advanced electronic sensor technology enhances the precision and responsiveness of safety mechanisms, ensuring systems react promptly to unsafe conditions or unauthorized access attempts.
Broader Integration with Safety & Automation Systems
In modern industrial environments, COMITRONIC’s stainless steel switches are only one part of an integrated safety architecture. These switches will work in tandem with various critical components such as safety PLCs, safety contactors or safety light curtains (including muting light curtains) to ensure real-time hazard detection and safe machine shutdown. Common peripheral safety devices like the emergency stop button, two hand station, and emergency stop rope pull are also present, all effectively managed by the safety PLC’s logic structure.
Advanced installations frequently incorporate safety relays, other forms of safety non-contact switches like RFID switches, mechanical interlock switches, or solenoid locking switches—each adding specific protective functions to the machinery. To maintain continuous system health, engineers also deploy standstill monitors, speed monitors, soft starters, and reversing contactors within their automation frameworks. For measuring the product itself, solutions such as measurement light curtains can be integrated.
Beyond motion and logic safety, electrical condition monitoring is equally essential. Devices like insulation monitors, battery monitors, current monitors, voltage monitoring relays, phase sequence relays, undervoltage relays, and undercurrent monitoring relays are often integrated to detect anomalies in power flow or equipment performance, with this data displayable on HMI Touch Panels or similar systems. To support reliable operation, high-quality power relays and regulated power supplies are essential.
Compliance and Safety Category Ratings
Each product is rated for high-level safety category compliance, such as Category 4 and SIL3, ensuring they meet the strictest global standards. This guarantees reliability in life-critical applications. COMITRONIC / BTI also emphasizes achieving the necessary level of performance for applications where operator protection and risk mitigation are paramount.
Wide Range of Industrial Applications
COMITRONIC / BTI supports safety needs across many industries including food and beverage, pharmaceuticals, packaging, robotics, and manufacturing. Their wide range of solutions—from electromagnetic locks to stainless steel interlocks—makes them adaptable to both standard and custom safety installations.
Maintenance personnel benefit greatly from these systems through reduced troubleshooting time, improved diagnostics, and safer intervention protocols during machine servicing.
With engineering precision and a commitment to safety, COMITRONIC / BTI continues to be a go-to provider for industries looking to elevate their machine protection and compliance strategies.
