Why Choose the Lovato Electric TL21012S Key-Operated Limit Switch?

The Lovato Electric TL21012S 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 model is operated from the left-hand side 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 TL21012S 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.
  • Left-side key entry supports installations with restricted frontal access.
  • 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.

Key Features

  • Lovato Electric T series limit switch.
  • Key-operated design without a reset button.
  • Left-side key insertion.
  • Angled “T” operating key.
  • 1NO+1NC slow-action contact arrangement.
  • 250 V rated insulation voltage.
  • 6 A conventional thermal current.
  • 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 from the left-hand side, 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 TL21012S 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.
  • Left-side actuation in restricted installation spaces.
  • Packaging and production machinery.
  • Material handling and conveyor systems.
  • OEM machinery and industrial control systems.
