Industrial Safety: How to Guarantee Active Protection and Automatic Machine Stop with the ESC-SFT Series from Elesa+Ganter. | REIMAN
In modern industry, true safety goes beyond blocking access: it requires the ability to electrically intervene and stop the production process immediately. To protect operators against mechanical risks, human error, and poorly closed doors, it is essential to rely on active cut-off devices.
The ESC-SFT range from Elesa+Ganter responds to this challenge by integrating, into a single component, the ergonomic handle and a highly reliable electrical safety switch.

Frequently Asked Questions (Q&A)
1. The Heart of the Solution: The Integrated Safety Switch in the ESC-SFT Series.
Historically, access protection required the mechanical mounting of a handle and the independent installation of an external electrical safety sensor/switch. This separation created points of failure, misalignment due to vibration, and signal lags.
The ESC-SFT series revolutionizes the sector by fusing the mechanical handle with an internal electrical safety cut-off mechanism:
What Does the Integrated Safety Switch Do?
-
Immediate Electromechanical Cut-off: As soon as the handle detects the slightest opening of the door, the internal safety switch opens the electrical circuit, commanding the autonomous and instantaneous stop of the machine.
Active Lock Against Startups: Absolute prevention of startup until the switch safety contact confirms the airtight closure of the access.
Safe Electrical Signaling: Direct connection to the installation's safety relays or programmable logic controllers (PLCs) via shielded industrial connectors.

Evaluation Criteria
Traditional Systems (Handpiece + Separate Sensor)
ESC-SFT Solution (Handle + Integrated Safety Switch)
Electrical Integration
It requires the installation, alignment, and wiring of two separate components.
1 single component: Mechanical handle with a pre-installed electrical switch.
Cutting Response Time
Subject to mechanical play and misalignment of the external sensor.
Immediate: The safety switch directly activates the opening of the handle.
Circuit Breaker Protection
External sensors exposed to impacts, dust, and debris.
Shielded switch: Fully protected inside the handle housing.
Cablagem e Conexão
Long and complex, with a greater margin for electrical errors.
Fast and standardized: Quick-connect connector for industrial safety circuits.
Aesthetics and Space
The access point is cluttered with brackets and protruding switches.
Clean, compact design with a hidden safety mechanism.
3. Strategic Advantages for Manufacturers and Industrials
-
Immediate Regulatory Compliance: Facilitates CE machine certification by incorporating safety switches certified according to European directives.
Autonomous Emergency Cut-off: Eliminates human risk — the safety switch disconnects the equipment's power without depending on operator action.
Durability in Severe Environments: The internal electrical mechanism is isolated against vibrations, dirt, and industrial washdowns.

Frequently Asked Questions (Q&A)
Q: How does the safety switch guarantee a stop if the door is left slightly open?
A: The internal safety switch features highly sensitive positive opening contacts. Any millimeter displacement of the handle out of the locked position breaks the electrical circuit and commands an immediate total stop.
Q: Does the operator need to press any button to trigger the safety switch?
A: No. The actuation of the safety switch is 100% mechanical and automatic: the very act of pulling the handle or the simple opening of the latch commands the electrical cut-off.
Q: Is the safety switch of the ESC-SFT range compatible with my existing safety relays?
A: Yes. The integrated safety switch uses standardized electrical contacts, allowing direct and simple integration into any safety circuit (Safety Relays or PLCs).
