The PSE EX piezo switch from Schurter, available from Relec Electronics, has achieved approval according to Atex Class II 2 G Ex ib IIB T4, enabling the switch to be employed in explosive facilities above ground.

This Atex protection level allows the PSE EX piezo switch to be used in applications in explosive atmospheres arising from a mixture of air, vapours or mists and other gases.

The PSE EX switch is typically used in oil and gas production systems, the petro-chemical industry, as well as in paint and varnish mixing facilities. Preparations for extending the Atex approval to include dust-Ex applications are underway.

We are proud to have one of the most comprehensive power supply ranges available, for both DC to DC and AC to DC applications. In addition, we offer a range of complementing products including EMC filters, switches and displays. Our aim is to build partnerships with customers and suppliers to both understand their requirements and to ensure a reliable supply of robust, yet technically advanced components that can be relied upon in the long term.

Power supplies, circuit protection and interface products form the backbone of our business. We work very hard to bring high-quality competitive products to the market, and our customers can be assured that any product we are promoting will not have reached them without full dialogue with the supplier together with a personal factory audit.

We believe the future is to offer our clients more choice thereby ‘adding value’ to their projects. This is achieved by offering custom products in all the lines we supply and by offering manufacturing services such as sub-assemblies and finished products. In our UK warehouse, we hold significant stocks of both standard and customer-specific parts and offer all the commercial services you would expect, including JIT, KANBAN, and specialist agreements tailored to suit individual customer needs.

Relec’s sales and technical support personnel, including our QA department, are all qualified engineers and are committed to ensuring that all aspects of our service meet and exceed today’s high expectations.
