PNOZsigma safety relay series

The PNOZsigma safety relay series offers more than ten different models, ranging from S1 to S10. The smallest relay has a housing width of just 12.5 mm, up to 50% narrower than most of the standard safety relays on the market. The PNOZsigma series is fully capable of performing the functions of about 100 other relays, including such safety related functions as E-STOP, safety gate, light curtain, or two-hand control on independent stand-alone machines. The smaller size of the relays substantially reduces the space required for housing in the control cabinet. The multi-functionality means users can standardize on a smaller number of relays, so there are fewer to purchase and stock, saving still more space. Mounting the Sigma safety relay on a DIN mounting rail requires no tools. The series offers removable wire connectors, that is, the wires stay with connector.
