Hengstler Safety Relais
May the safety be with you...
The perfect choice:
In the railway-business exist a variety of application with most divers requirements. This starts with demands towards the components due to restrictions in space up to parameters given by the control layout. In our product range you can select among a wide range of characteristics to find a suitable relay for your individual application.
Many of our relays used in railway applications are fulfilling the requirements of UIC 736e. Furthermore all relays are cULus approved which helps to meet fire prevention demands in railway vehicle.
- Number of contacts: From 2-10 contacts per relay
- Contact combination: Different combinations of NO and NC contacts available.
- Coil voltage: Standard and customized coil voltages available.
- Contact plating: Up to 5 μm Au for high reliability at small loads.
- Versions: Lying and standing safety relays as well as flat relays with low profile to meet all kind of different space restrictions.
Applications:
Plattform screen doors, Dead man switch, Break control, Signaling systems, Axe counting, Signal interlock, Door Controls, Autonome trains

High number of contacts, robust design: 462/464
Products of this category are always used where high currents (up to 10A) need to be switched and at the same time high contact reliability is mandatory. Exposure to high values of shock and vibration are standard in railway application. Due to the robust design Hengstler Relays can be easily used in this environment. Depending on the selected product family it is possible to choose up to 10 contacts in a variety of combinations, with up to 5 μm gold plating. Relays of these group are fulfilling the standard for signaling relays UIC 736e.
Flat Relays : 472/473/480/466
If height is the restriction in your application, flat relays with a mounting height of e.g. 15,7 mm help you two achieve a high packing density. Depending on the chosen product family up to 10 contacts in diff erent contact combinations are available. Some families are also fulfilling the standard of UIC 736e. Relays of product family 472/473 help you to achieve an easy and well-arranged PCB design by a user friendly pin layout.
Bistable Relais:
In safety applications where it is mandatory that the switching state of the relay is kept also aft er a voltage breakdown, bistable safety relays of Hengstler can be used. This special feature is realized by a magnetic remanence drive.
Activation by load current:
For special applications we can off er solutions where the load current is led directly through the coil and can control the correct function of the load.
Our Special Strength - Safety Relays
Don’t compromise on the protection of people and machinery. Safety relays with 2 to 10 force-guided contact sets provide you with security, as they prevent danger to individuals or valuable tools in the event of a fault through appropriate circuitry and system configuration. They are also becoming increasingly important internationally. Our safety relays are as small as possible but of the highest reliability and switching safety. Furthermore, numerous variants offer the desired flexibility for your application.
The market for safety relays is inherently particularly demanding, one that we cultivate intensively and for which HENGSTLER, since mid-1996 together with its sister company KACO, today offers the world’s broadest product range.
The ambition to make our environment a safer place can be seen everywhere. Known are emergency stops at ski lifts, at escalators in the shopping mall or after a flight at the baggage carrousel. Although less obvious, but by far not less important, the same principle can be found everywhere in Railway infrastructure where it is about to guarantee safety for both humans and machines. Railway technics, same as process technology and machine building, do have one thing in common – since decades they use safety relays (force guided relays acc. to IEC 61810-3) to control safety relevant functions. Compared with other solutions they offer next to the deterministic working forced guidance, the benefit of a galvanic isolation. Specifically for the railway industry the EN 50155 is of importance. It describes
in detail the requirements related to a relay towards voltage fluctuations, mechanical parameters and environmental conditions.
Next to the control function, the safety relay needs to fulfill the high requirements on signal availability. Related failures bear the risk of having a high impact on the railway operation. With high contact forces and the relative movement while opening and closing the contacts (self-cleaning) relays from Hengstler ensure high signal availability. In case of switching low currents Hengstler offers for some relay families contacts with up to 5 μm gold plating. Last but not least a forward-looking product management is needed to fulfil the demand for a long availability of the chosen product.
