Relays with forcibly guided contacts according to IEC 61810-3

Our relays are used as the heart of applications of functional safety. So wherever there is a risk of accidents. Whether for a track crossing, a lift, robots, medical lasers, X-ray equipment or construction cranes, to name but a few applications. The special feature of our relays is the forced guidance. This design feature of the relay connects the relay contacts with each other in such a way that when one contact is welded together, all other counter-functional contacts can no longer close. This makes monitoring of the load and feedback circuits very simple and safe.

With 8 relay series and 13 housing types, we can cover almost all customer requirements. All our relays can be individually adapted to customer requirements and, thanks to lean production, are so flexible that even small series and special solutions can be produced cost-efficiently and with short delivery times.

The range of relays covers switching currents from 3 mA to 16 A. Relay coils up to 240 VDC are also available energy efficient. Also available are variants according to special standards and customer requirements.

Optical miniature encoders

MEMS (Micro Electro Mechanical Systems) are gaining in importance. Miniaturization cannot be realized without MEMS, especially when conventional technologies reach their limits. Our optical miniature encoders EOIR007 are the result of a profound knowledge of electromechanical systems combined with a completely new mode of operation of optical encoders.

The code disk of the incremental encoder is equipped with 128 optical segments, which in fact bundle and reflect the incoming light without a blind area. Extremely high repeat accuracy is provided by the exact signal edges both at small angular movements and at very high speeds > 100,000 rpm. Due to its high electrical efficiency, the system manages with 20 to 30 mW and is particularly suitable for energy-efficient design and battery-powered off-grid systems.

The system has been designed for integration into miniaturized customer systems such as motors, pumps, valves, air turbines, etc. The dimensions and connection variants of the encoder board can be adapted to the customer’s system.

Custom sensors

Sensor technology is a wide field. We at ELESTA GmbH see our core competence in the development and production of sensors for industrial automation and functional safety systems.

Our development team covers all areas of product development. From safety engineering and embedded programming to all the usual disciplines of electronics development. The development is based on the V model (ISO/IEC 12207:2008) which is embedded in our lean development process.

Product development also includes the development and implementation of production processes, including product and production FMEA. Thus the customer can fall back on a complete service which covers the entire product life cycle from product design to production to product discontinuation.
