Schmersal supplier in Romania
Safety relays and switches for machine protection
Founded in 1945 · Headquarters: Wuppertal, Germany
Who is Schmersal and what does it make?
Schmersal is a German manufacturer of machine safety components, established immediately after the Second World War in Wuppertal, where the company is still headquartered today. The range covers safety switches and solenoid interlocks for doors and movable guards, non-contact safety sensors, optoelectronic safety light barriers and curtains, plus monitoring modules and safety controllers for integration into line automation. For Romania we can quote both individual components and complete protection sets for a cell or a line.
The company started from the production of components for lifts and, from 1947, of mechanical switching devices, and the current range includes both mechanical switches and electronic products. The family of ATEX-certified devices under Directive 2014/34/EU covers explosive atmospheres, and the BDF20 control panels and SD gateways are products from the Schmersal range for integrating safety devices into line automation.
On retrofitted older lines, the Schmersal range allows worn safety switches to be replaced with mechanically compatible versions that add monitoring functions — useful when upgrading a robotic cell or a packaging line without rewriting the entire safety architecture.
What do we supply from the Schmersal range?
| Product | Description |
|---|---|
| Safety switches and solenoid interlocks | Electromechanical devices mounted on doors, covers or movable guards, which break the control circuit on opening and, in the interlocking version, hold the door closed until the machine reaches a safe state. They are used on robotic cells, presses and machine tools where frequent operator access must be combined with a certified stopping time in line with safety standards. The customer should tell us the door type and the locking force required. |
| Non-contact safety sensors | Sensors that detect the position of a guard without direct mechanical contact, reducing wear and allowing installation in environments with vibration or dirt. They are chosen on the basis of the switching distance and the safety performance level required (PL according to ISO 13849), on light plastic or aluminium guards where a classic mechanical switch would deteriorate quickly. |
| Optoelectronic light barriers and curtains | Optoelectronic protective devices that create an invisible detection field around a hazardous area, stopping the machine when the beam is interrupted. They are sized according to the detection resolution (finger, hand or body) and the safety distance calculated from the stopping time of the protected machine. |
| Safety controllers and SD gateways | Programmable or fixed-logic modules that combine the signals from several safety devices and decide on the controlled stopping of the machine. SD gateways and safety field boxes (SFB) connect these signals into existing automation networks, useful when retrofitting a line with several dispersed emergency stop points. |
Why Schmersal?
- A functional safety range — from the simple mechanical switch to the programmable safety controller
- ATEX 2014/34/EU certified devices for explosive atmospheres in the chemical industry or combustible dust

How do we supply Schmersal in Romania?
We source Schmersal components to order through EU supply channels, usually within 1–4 weeks. We do not keep our own stock of the Schmersal range and we do not promise permanent availability. For an accurate quotation we need the exact product code or, if you do not know it, the type of guard and the safety performance level required by the risk analysis. Technical data comes from the manufacturer's technical documentation.
We check the availability of a specific part individually with the supplier; programming of software-configurable safety controllers is outside our offer.
Frequently asked questions about Schmersal
What is the difference between the Schmersal AZ215 and AZ315 switches?
AZ215 and AZ315 are safety switches from the manufacturer's AZ range; the design differences (housing, actuating direction, contacts) are confirmed from the Schmersal datasheet for the code requested. The choice depends on the type of protective door, the actuating direction available and the performance level requirements of the safety function.
How do I choose a suitable SD gateway for a Schmersal system?
The choice starts from the network protocol already used in the automation, because the SD gateway translates the signals of Schmersal safety devices to the plant fieldbus. What matters is the number of devices to be connected, the type of switches and sensors in the installation, and whether extended bit-level diagnostics are wanted. We recommend consulting the datasheet published by Schmersal for exact compatibility with the programmable controller used.
Do you supply Schmersal safety equipment in Romania?
Yes, we source switches, solenoid interlocks and light curtains from the Schmersal portfolio to order, starting from the exact product code. We do not keep this range on our shelves, and the lead time is usually 1–4 weeks from the order. We recommend sending the full code and, if possible, a photo of the label of the existing equipment for correct identification.
What should I send for a safety switch quotation?
We need the full product code from the housing or the wiring diagram, the voltage and the type of contacts required, and the safety category required by the application. If the equipment is already installed, a clear photo of the nameplate helps avoid confusion between close variants in the same family. Mentioning the safety standard applicable to the installation speeds up preparation of the correct quotation.
How do I request a Schmersal quotation?
Send the Schmersal code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
