What does this relay socket do in a control panel?
It provides the plug-in base and field wiring terminals for compatible 11-pin general-purpose relays, allowing quick relay replacement without disturbing the panel wiring. The PF113A-D mounts on DIN rail or can be screw-mounted to a surface.
Which relay type is it designed to accept?
It is designed for 11-pin, 3-pole plug-in relays (commonly 3PDT style) from Omron’s compatible families such as MKS, and related 11-pin plug-in relay formats that match the same pin layout.
How is it mounted?
Mounting options are DIN rail mounting and surface (panel) mounting using the socket’s fixing holes.
What terminal style does it use?
It uses screw terminals with a box-clamp wire locking system to secure conductors reliably.
What wire sizes can be used?
Supported conductor sizes are 0.5 mm² to 2.5 mm² (approximately AWG 20 to AWG 14), for both solid and stranded conductors.
How much insulation should be stripped from the wire?
Recommended strip length is 6–7 mm to ensure good clamping while minimising exposed conductor.
What tightening torque should be applied to the terminal screws?
Maximum recommended terminal screw torque is 0.8 Nm to help avoid damage while achieving secure clamping.
What are the voltage and current ratings for the socket terminals?
Rated voltage is 300 VAC (IEC and UL). Rated current is 12 A (IEC). UL rated current is 10 A (or 12 A at 150 VAC).
What is the terminal protection level?
Terminal protection degree is IP20, meaning the terminal area provides basic finger protection against accidental contact with live parts under normal installation conditions.
What ambient temperature range can it operate in?
Operating temperature range is -25°C to +85°C (without icing/condensation considerations being addressed by the socket specification).
Does it include a hold-down clip to secure the relay?
Yes. A hold-down clip is included to help retain the relay in place, which is useful in panels subject to vibration or when frequent relay handling is expected.
What are the approximate dimensions and weight for panel layout planning?
Approximate socket dimensions (unpacked) are 42.8 mm (W) × 52 mm (H) × 31 mm (D), and the weight is about 65 g.
Is it compliant with RoHS requirements?
Yes. It is RoHS compliant in line with Directive 2011/65/EU and Delegated Directive 2015/863 (as stated for PF113A-D).
