General-purpose Relays New Super MK Relays. Models with Latching Lever Added to the Series. • Same mounting and internal wiring as the previous Super MK Relays • Built-in mechanical indicator enables checking contact operation. • Two modes can be used to check circuits for models with latching lever. • Nameplate provided on models with latching lever. • All materials are RoHS compliant. • UL and IEC (TÜV) certification. For the most recent information on models that have been certified for safety standards, refer to your OMRON website. Features Models with Latching Lever Operating Method for Latching Lever Operation indicator * Relay in Normal Operation Slide the latching lever to the first position, then press the yellow button with an insulated tool to operate the contact. Slide the latching lever to the second position. (The contact is now in the locked position.) Mechanical indicator Latching lever DC: Blue AC: Red Yellow button * The operation indicator is built in only on specified models.

Models without Latching Lever Models with Latching Lever Sockets See below for Socket dimensions. Socket Maximum carry current Surface-mounting Socket (for track or screw mounting) Finger-protection models 10 A Note: Use the Surface-mounting Sockets (i.e., finger-protection models) with “-E” at the end of the model number. When using the PF083A and PF113A, be sure not to exceed the Socket's maximum carry current of 5 A. Using at a current exceeding 5 A may lead to burning. Round terminals cannot be used for finger-protection models. Use Y-shaped terminals. PF113A-E (Conforming to EN 50022) Terminal...

Terminal Arrangement Mounting Holes Mounting Holes Hold-down Clips Mounting Tracks * This dimension applies to the PFP-50N Mounting Track. * A total of twelve 25 × 4.5 elliptic holes is provided with six holes cut from each track end at a pitch of 10 mm. Mounting Height with Sockets Surface-mounting Sockets Three poles Note: PF083A(-E) and PF113A(-E) allow either track or screw mounting.
