Why Choose the Lovato Electric TL21012 Key-Operated Limit Switch?
The Lovato Electric TL21012 is a robust key-operated industrial limit switch designed for reliable position detection and mechanical interlocking in machinery and automation systems. As part of the Lovato Electric T series, it features a polymer thermoplastic housing manufactured to dimensions specified by EN 50041.
This limit switch is operated by an angled “T” key and is supplied without a reset button. Its 1NO+1NC slow-action contact configuration provides one normally open and one normally closed contact for integration into machine control, monitoring and signalling circuits.
With a rated insulation voltage of 250 V, a conventional thermal current of 6 A and an IP66 housing protection rating, the TL21012 is designed for dependable service in industrial environments. Its PG13.5 cable entry and self-releasing screw terminals support straightforward electrical installation.
Key Advantages
- Reliable key-operated limit switch for industrial machinery.
- Angled “T” key provides positive mechanical actuation.
- 1NO+1NC slow-action contacts support control and monitoring circuits.
- Durable polymer thermoplastic housing with IP66 protection.
- Mechanical life of more than 10,000,000 operating cycles.
- Standardised dimensions in accordance with EN 50041.
Key Features
- Lovato Electric T series limit switch.
- Key-operated design without a reset button.
- Angled “T” operating key.
- 1NO+1NC slow-action contact arrangement.
- 250 V rated insulation voltage.
- 6 A conventional thermal current.
- PG13.5 cable entry with self-releasing screw terminals.
- IP66 body housing protection.
Reliable Position Monitoring for Industrial Machinery
Key-operated limit switches use a separate mechanical key to actuate their internal contacts. When the angled “T” key enters or leaves the switch head, the slow-action contacts change state at defined operating points, allowing the control system to monitor the position of a moving machine component.
The Lovato Electric TL21012 combines a robust thermoplastic housing, long mechanical operating life and standardised mounting dimensions. Its 1NO+1NC contact arrangement enables both control and status-monitoring functions within industrial automation circuits.
Typical Applications
- Machine position detection and monitoring.
- Industrial access panel and cover detection.
- Packaging and production machinery.
- Material handling and conveyor systems.
- Automated equipment and assembly lines.
- OEM machinery and industrial control systems.
