• Solid State, Coded Magnetic Safety Switches
• Standalone, Volt-Free Contact Outputs
• Dual Colour Indication on the Safety Switch
• Shock and Vibration Proof
• IP67 & IP69K, Fully Sealed
The Mechan HE-Series are coded magnetic safety switches. They can be used as a standalone safety switch or combined with our SCU1 safety relay for a CAT4 SIL3 PL-e approved safety system.
The HE-Series is designed to combine the ease of use and maintenance of a simple magnetic safety switch along with the improved security, performance levels and indication of an electronic safety switch.
The fully encapsulated HE safety switches withstand vibration, wash down and most harsh environments, making them ideal for use in the food processing / filling, packing industries as well as many other non-locking machine guard applications.
Available in all the popular housings, the HE safety switches are the ideal upgrade from traditional non-coded magnetic safety switches.
Fit & Forget - Safety from Mechan
The Mechan HE-Series is a coded magnetic safety system. Comprising a slim-line Safety Control Unit and solid state safety switches coded magnetically operated, non contact safety switches.
Designed to combine the advantages of magnetic safety switches and the improved performance, security and operation of Mechan’s electronic safety switches, the HE safety switches can withstand harsh environments, (rated down to -30C and used in the Arctic circle). They can also be supplied in 316 grade stainless steel suitable for wash down areas in the food processing and packaging industry.
The SCU-1 is a 22.5mm wide, DIN rail mounting safety control unit, tested and approved by TUV to work with the HE-Series safety switches.
Operating voltage is 24Vac/dc the SCU-1 has 2 NO + 1 NC outputs rated at 4A/230Vac or 2A 24Vdc. With switch selectable manual or automatic reset function, and LED indication of Power and each input channel the SCU-1 is a simple control unit link into your existing safety system
The HE safety switches are fully encapsulated into a variety of shapes and sizes, in either ABS or 316 grade Stainless steel housings, helping to make installation on all types of guarding systems / applications as easy as possible. The unique HED dual switch, capable of monitoring 2 doors with one switch makes monitoring double doors even easier.
The HE safety switches have a coded magnetic input ensuring the switch cannot be overridden by a simple magnet / piece of metal / screwdriver etc and 8 – 10 mm switching distance makes the HE safety switches easy to install, tolerant to misalignment and providing a long and trouble free operating life.
Each switch has up to 2 x N/O + 1 N/C bi-directional solid state outputs. The electronic activation of all three contacts simultaneously eliminates the problem of ‘lockout’ and ensures the correct operation of the safety circuits every time.
The HE switches have built in dual colour LED indicators for easy identification of switch status and fault diagnostics.
When installed and power is applied, and the switch and actuator are within the specified operating range, the N/O Outputs will be closed, the N/C Output will be open. When the actuator moves out of the operating range, the N/O Outputs will open, the N/C Output will close.
The HE safety switches are available with a pre-wired 3 / 5 or 10 metre cable. Longer cables can be ordered if required. Some versions are available with an M12 Leaded Quick Disconnect option.
The HE safety switches have been designed to connect to the SCU-1 Safety Control Unit but can also work with other safety relay products. (Please check input specification first)
