Magsafe 786-300

Magsafe provides a new approach to safety gate interlocking and access control solutions. Magsafe offers a combination of safety innovation and cost effective design. An electro-magnetic interlock system for controlling personnel access through the gates and doors set within the perimeter safety fencing or screens surrounding potentially hazadous machinery. The Magsafe magnetic safety gate interlocks provide interlocking and access control for a wide range of applications in the food and drinks, automotive, buildings materials, paper industries and many others.

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 failue of the product.

Magsafe now offers the ability to monitor up to 2 magnets from a single low cost (DIN rail mount) Control Unit or the system can be extended by connecting Extender Modules (DIN rail mount) to allow for up to 8 monitored magnets on one system. The Magsafe system provides even greater flexibility in safety gate/access control design.

This facility makes it ideal for the great majority of work cells, typically with 1 or 2 safety gates/doors providing access through the perimeter safety fencing to a dangerous machine. Magsafe's innovative design allows it to be both flexible and user friendly whilst still offering the customer an ideal low cost safety gate interlocking solution.

Magsafe incorporates a number of innovative customer driven design features including:

  • Using safety light curtain technology which continuously monitors the on and off state of the magnets. This ensures the system detects a gate open or closed condition.
  • Using magnetic force rather than mechanical removes the problems that plague existing gate locks due to liquid and dirt exposure, which in combination with the rigors of daily operation causes fatigue and leads to mechanical failure.
  • E-Stop relay included reduces overall cost of installation.

A typical system comprises of electromagnetic gate locks, control unit / extender module(s), local access control unit and connection cables. The Control Unit contains all the control electronics for the Magsafe system including run-dowm timers for gate release, E-Stop inputs, External Device Monitoring (EDM), connection for up to 2 monitored magnets, LED output display with output signals for driving a PLC input and dual channel safety output relay contacts. In addition it provides connection for the Extender Modules which allow up to 1 or 2 magnets per Extender Module. Up to 3 Extender Modules can be added allowing for a total of 8 monitored magnets on a single system.

The control system provides up to EN 954-1, Category 4, EN ISO 13849-1, PL e and EN 61508, SIL 3 safety integrity, ensuring suitability for the majority of machine safety applications. Magnets are available in 2 material options, nickel plated steel and stainless steel, ideal for use in food, drinks and other similar applications. They are also available in 2 sizes, 63mm and 38mm Diameter. The magnets provide a holding force up to 500 N per magnet (model dependant). 3m and 10m cable options are available for magnet to control box connection. A Local Access Controller is also available providing a 'traffic light' entry condition indication for the operator driven by the run down timer. The Local Access Controller has 5m and 10m cable lengths. Alternatively the user has the option to configure their own access control interface.
