Cynergy3 RSF56 Series

Cynergy3 RSF56  Series

The RSF56 internal fitting Polyphenylene Sulphide (PPS) float switches are part of the RSF50 series offering compact design and a number of options including choice of maximum power (25VA or 100VA), mounting (1/8" mounting thread or M12 connector), viton or nitrile gaskets and ETFE or PVC leadouts. The RSF56 switches can be mounted either from the bottom or from the top of the tank and therefore access to the inside of the tank is required. The switch action may be reversed by removing the float, inverting it and refitting to the stem. The RSF56 float switches are WRAS (with PVC leadouts only), NSF and UL approved and can be operated in temperature range up to -10°C to +120°C (with ETFE leadout option).
