The RL75-4S is a type of receptacle, or socket, used primarily with spring-loaded test probes in electronics testing, specifically with the P75 series of pogo pins. Its purpose is to create a removable and replaceable connection point for probes on printed circuit boards (PCBs) and other equipment.

Dimensions and material:

• Length: 30 mm.
• Outer Diameter: 1.32 mm.
• Mounting Hole: Requires a drilling size of 1.3 to 1.35 mm for installation.
• Material: The receptacle is typically made from metal, with a gold-tone or gold-plated finish to ensure good electrical conductivity.

• Easy replacement: If a test probe becomes damaged, it can be quickly swapped out without having to desolder and resolder the entire connection, which saves time during maintenance.
• Long-term fixture life: By allowing for the replacement of probes, the overall life of the test fixture or jig is extended.
• Versatility: Receptacles support different types of probes from the PL75 series, allowing for flexible testing configurations.
• Stable connection: The design provides a secure point of contact for the test probe, which is important for maintaining stable and repeatable test results.

• Application: The receptacle is widely used in test jigs for in-circuit testing (ICT) and functional circuit testing (FCT) of electronic devices. This allows for quick and reliable testing of boards.
• Mating component: It is designed to be used with the PL75 and P75 series of spring test probes, commonly known as pogo pins.
• Removability: Receptacles are a contact device that is installed on the PCB or test fixture. Test probes can then be plugged into and removed from the receptacle as needed, allowing for quick and easy replacement of faulty or worn-out probes.
• Wire connection: The "S" in the RL75-4S model name denotes a solder-type connection, indicating that the receptacle has a soldering post for wiring connections. Other variants exist, such as the wire-wrap type ("W").
