mGard is the premier range of modular robust trapped key interlocks for heavy duty applications. Trapped key interlocking is a tried and tested method of mechanically safeguarding dangerous machines and hazardous processes, and is suitable for category 4 (EN 954-1) applications. It is called "Trapped Key" as it works by releasing and trapping keys in a predetermined sequence. After the control or power has been isolated, a key is released that can be used to grant access to individual or multiple doors.
The principles of trapped key technology apply to all industries where it is essential that all energy sources are isolated before gaining access to machinery. Almost all safety issues can simply be solved by selecting the required products in the following order
- Power/Control isolation
- Key exchange units
- Door locks & actuators
Benefits of mGard
- No wiring on the installation
- Pattented runner bar system
- Pure mechanical configurations can be used in ATEX zones 1,2
- Create pre-determined safety procedures
- Designed for use in harsh environments (dust moisture and vibration)
- Robust heads and actuators and handles (with missallignment) |

AZM range solenoid interlocks, operating in combination with control elements of a machine, e.g. fail-safe standstill monitors or fail-safe delay timers, ensure that sliding, hinged and removable guarding devices, such as grids , hoods or doors, cannot be opened until hazardous conditions (e.g. running-down movements) have come to an end.
These solenoid interlocks are also used for cases in which the opening of a guarding device represents a non-permissible intrusion in a production process.
In combination with AES and AZR range safety monitoring modules, the AZM range solenoid interlocks achieve Control Category 3 or 4 to EN 954-1, subject to suitable circuit arrangements. Examples of circuits for solenoid interlocks are shown in the Schmersal Control Circuit and Applications Handbook.
Schmersal make both standard and AS-i Safety at Work solenoid interlocks.

Magsafe is Smartscan’s latest innovation in machine safety. An electro-magnetic interlocking system for controlling personnel access through the gates and doors set within the perimeter safety fencing or screens surrounding potentially hazardous machinery.
The key design element in Magsafe was to lock the door using magnetic force rather than by mechanical means and to remove the problems that plague existing gate locks due to liquid and dirt exposure in combination with the rigors of daily operation. This causes fatigue and leads to mechanical failure of the product. The ability to withstand harsh industrial environments such as water, dust and corrosive liquids Magsafe is the perfect solution for most guard locking applications.
In addition to this Smartscan has applied its safety light curtain technology background to the safety gate interlocking market by providing a system control unit which continuously monitors the on and off state of the magnets. This ensures the system detects when the gate is open and when it is closed. Only when the gate is closed and the magnetic locking force applied, will the control system allow machine operation. |
|
Designed to control access to the dangerous or protected areas, this device is installed in any kind of door, gate, housing, and permits remote unlocking from a distance.
Equipped with a forced opening contact, it permits the detection when the access is closed again. |

The Control is a PID controller that makes any solenoid valve "intelligent", the choice of solenoid valve depending on the user's application (from among the 601, Posiflow, Preciflow solenoid valves etc), and on the installation, which may be in a critical environment.
The Control can control 2 loops in the same manufacturing process, whether they are open, closed or double (cascaded). For instance:
- In an open loop: the Control adjusts the valve's pressure or flow rate (without a sensor) by measuring the feedback value.
- In a closed loop: the Control continuously compares the set pressure or flow with the set point thanks to a signal emitted by the sensor. The benefits? Very precise control (hysteresis of 1%) that reacts to external interference
- In a double loop (with 2 sensors): the first loop adjusts the valve's pressure or flow for optimum control, while the second loop returns the signal of the relevant feedback value (pressure, position, force etc). Because the process's response time is integrated into the control process as a whole, the latter is more stable. |
