Product Overview
Finder 40.52 Plug-In Relay on a 95.75 Screw Terminal DIN Rail Socket, Green LED Module Fitted
Condition
Used, clean and in good condition. The relay is the clear cased Finder 40.52, with Made in EC-03 molded down the side of the housing and 250V and 8 A 250V printed across the front next to the contact symbols, and the coil winding and contact stack are visible through the plastic. The socket underneath carries the Finder logo and TYPE 95.75 on its end wall, with c-UL-us 10A 300V, CSA 10A 250V, CE and IGr C 250 molded into the face beside the terminal diagram. The steel retaining clip is fitted over the relay and holding it down. Under close-up the screw terminals are clean, with unrounded cross slot heads and the clamp plates backed off ready for wire. The indicator module plugged into the end is molded 24 Vdc with a green LED lens on top and a polarity marked schematic on its side showing the LED, series resistor and diode. Against the millimeter ruler the assembly measures roughly 70 mm end to end.

Product Overview
This is a made-up Finder relay assembly: a 40.52 two pole changeover relay, the matching 95.75 DIN rail socket with screw terminals, and a plug-in green LED indicator module, sold together as one three-piece group. The relay front is printed 8 A 250V for the contacts. The socket face carries the full wiring map molded into the plastic, A1 and A2 for the coil and two changeover sets numbered 11-12-14 and 21-22-24 with COM, NC and NO called out, so the terminal you need is readable without a datasheet in hand. The socket also carries its own agency marks, c-UL-us 10A 300V and CSA 10A 250V, along with CE and IGr C 250. The indicator module is the polarity marked 24 Vdc type, green lens, with the LED, dropping resistor and diode drawn on the module body. Coil voltage stamped on the relay itself is not legible in these photographs. Not confirmed - verify the coil marking on the part in hand before you energize it.

Applications
- Panel builder adding an interposing relay between a PLC output card and a solenoid or contactor coil, with a lit indicator for troubleshooting
- Maintenance electrician keeping a complete spare on the shelf so a failed relay is a plug swap and not a rewire
- Machine builder who wants two independent changeover contacts on one DIN rail slot for interlock and signal duty
- Automation instructor or hobbyist building a training rail where the green LED shows coil state at a glance
Frequently Asked Questions
How many contacts does the 40.52 give me?
Two changeover sets. The socket diagram in the photos numbers them 11-12-14 and 21-22-24, labeled COM, NC and NO, and the relay front is printed 8 A 250V for the contacts.
What coil voltage is this assembly set up for?
The indicator module is molded 24 Vdc and is polarity marked, which is what the photographs confirm. The coil marking on the relay itself is not legible in these images. Not confirmed - read the coil voltage off the part in hand and check it against the Finder datasheet before applying power.
Does the socket mount on standard DIN rail?
The 95.75 base is built for rail mounting and the photographs show the rail channel across the back with the sliding release tab at one end. The terminals are screw type with captive clamp plates, so it takes bare wire or ferrules without any special tooling.
Has this assembly been electrically tested?
No test result is published with it. The grade is Used, clean and in good condition from visual inspection, and the photographs plus the molded ratings are what we can stand behind. Plan on a coil pull-in check and a continuity sweep of both contact sets on your bench before it goes into a live panel.
What am I actually taking on with a used relay assembly like this one?
You are getting a three-piece group, relay, 95.75 socket and 24 Vdc LED module, used, clean and made up here rather than a new sealed part. We stock more than one of these, so the photographs show a representative assembly. Nobody has run it on a bench for you, so the printed ratings and the pictures are the specification, and the coil marking is the one thing you should confirm on arrival. Shipping is $8 flat rate and free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Finder built the 40.52 to be the anonymous blue rectangle nobody thinks about until a machine goes quiet. Clip it back onto a rail, watch the green lens come up, and let it go back to being ignored.
