What Is a Slim Relay Socket? A Quick Guide to the 41F-1Z-C2

Control cabinets keep getting denser. PLCs, power supplies, terminal blocks and interface relays all compete for the same DIN rail, and every millimetre of width matters. That is exactly the problem the slim relay socket was designed to solve.

What does a relay socket do?

A relay socket is the mounting base between the relay and the control wiring. It clips onto the DIN rail, takes the field wiring on its screw terminals, and holds the plug-in relay. That separation is worth more than it looks:

• Faster installation — wire the socket once; the relay simply plugs in.
• Easy maintenance — a worn relay can be swapped in seconds without touching the wiring.
• Clean isolation — interface relays in sockets isolate sensitive PLC outputs from field loads.

Meet the CHOLON 41F-1Z-C2

The 41F-1Z-C2 is CHOLON's slim relay socket for 41F-series slimline interface relay modules. It is built for everyday industrial control work — machine panels, PLC interface cabinets, building automation and similar applications where many channels sit side by side.

Why these details matter

PA6 housing. Polyamide 6 is the standard engineering plastic for relay sockets: electrically insulating, mechanically tough and suited to industrial environments.

H62 brass connecting pieces. Brass offers high conductivity and good corrosion resistance, which keeps contact resistance low and stable over years of service.

0.6 N·m tightening torque. Tightening the M3 screw to the specified torque gives a firm, reliable connection without damaging the terminal — loose terminals are one of the most common causes of panel faults.

≥ 2500 V dielectric strength. Solid insulation between circuits is what makes an interface point safe to use between the control side and the field side.

Choosing a slim relay socket: a short checklist

• Match the socket to your relay series and pin layout.
• Check the rated load against your actual switching current and voltage.
• Confirm the terminal type (screw or push-in) your panel standard requires.
• Use the specified tightening torque during installation.

If you know the Hongfa HF41F, you already know this format. The 41F class of 6.2 mm slim interface relays is a control-panel standard, and the CHOLON 41F-1Z-C2 is the socket built for exactly that class of relay.
