Panasonic Electric Works SFM series 2-pole safety relays

Panasonic’s SFM series safety relays offer power contacts on both NO (6A) and NC (4A) sides to control loads directly without another relay in between

Panasonic changed the way they designed safety modules by bringing a low profile 8-pole safety relay onto the market. Now the launch of the new 1a1b SFM relay will start the next phase of the market revolution. With a height of only 7.8mm and reflow soldering capability, SFM provides great design possibilities and is ready for future production processes.

As all Panasonic Industry safety relays, SFM offers power contacts on both NO (6A) and NC (4A) side to control loads like valves directly without another relay in between. The silver alloy contacts can handle low level loads down to 10V 1mA as well to support e.g. signaling boards in the railway sector. A very high shock and vibration resistance ≥ 20g, low coil holding power of 100mW, an ambient temperature range from -40°C to 85°C and reinforced insulation ≥ 5.5mm (V=230V overvoltage category III, 6KV) on NO side contribute to an almost unlimited field of applications.
