Robust relays with 5 mm width offer high packing density for space-constrained applications

The PF relay can support load switching up to 6 A at 250 V ac and has nominal size of 28 mm x 15 mm x 5 mm. The relay is also available in a bent-pin option for horizontal mounting in low-profile designs. The wide coil voltage range of 4.5 V to 60 V dc enables the PF relay to be used in many applications, with a nominal power consumption from 170 mW to 217 mW, depending on the coil voltage applied.

The PA-N relay is the smallest 5-A ATEX relay at 20 mm x 12.5mm x 5 mm. This power relay supports load switching up to 5 A at 250 V ac or 5 A at 30 V dc. A low nominal operating power of 110 mW enables high-density mounting, using a coil voltage from 3 V to 24 V dc. The relay is available with either a normally open or normally closed contact.

The PF relay is compliant with EN 60335-1, Clause 30 for resistance to heat and fire up to 85°C. The relay is capable of withstanding 4 kV breakdown voltage, with a minimum creepage distance of 8.0 mm between the contact and the coil terminal, and a minimum clearance distance of 6.0 mm.

For harsh, hazardous or potentially explosive environments, the PA-N relay is ATEX-certified to switch currents up to 5 A, and can be operated at temperatures up to 110°C. It also features reinforced insulation according to IEC 61010-2 standards.

Both relays are suitable for use in relay interface modules, extension boards for power relays or programmable logic controllers, in which the relays provide safe switching and isolation between the signal and load circuits. The PF and PA-N relays can handle a wide variety of load behaviors, including the high inductive loads of valves or motors.
