Why Choose the Finder 55.14.9.012.0001 7 A 4PDT PCB Relay?
The Finder 55.14.9.012.0001 is a versatile 7 A miniature general-purpose electromechanical relay designed for dependable switching in industrial automation, electrical control equipment and PCB-based electronic assemblies. Part of the established Finder 55 Series, this relay combines a 12 V DC coil, four independent changeover contacts and a compact housing for applications requiring multiple switching functions from a single control signal.
Featuring a 4PDT (four-pole double-throw / 4 CO) contact configuration, the Finder 55.14.9.012.0001 offers four separate changeover contact sets, each providing normally open, normally closed and common connections. Its 7 A rated contact current and 250 V AC rated contact voltage make it suitable for appropriately rated industrial control loads, signalling circuits and electrical equipment.
This specific .0001 version features RT III wash-tight protection, silver nickel (AgNi) contacts and PCB through-hole mounting. Its four-pole design is especially useful where several circuits need to be switched simultaneously without installing multiple individual relays. With a nominal 1 W DC coil and a compact construction, the Finder 55.14.9.012.0001 provides a practical solution for automation engineers, electronic equipment designers and OEM manufacturers.

Versatile Four-Pole Changeover Switching
The Finder 55.14.9.012.0001 is designed for applications requiring several electrical circuits to change state simultaneously. Its four independent changeover contacts are operated by a single 12 V DC electromagnetic coil, allowing one control signal to operate multiple switching functions.
When the coil is energised, each common contact transfers from its normally closed terminal to its normally open terminal. When the coil supply is removed, all four contact sets return to their normal positions. This arrangement is useful for applications such as auxiliary switching, status signalling, electrical interlocking and the control of multiple low-power or appropriately rated loads.
Unlike a force-guided safety relay, the Finder 55.14.9.012.0001 is a general-purpose electromechanical relay. Its four changeover contacts should not be assumed to provide certified force-guided contact monitoring. Where safety-related switching is required, the complete control architecture and the suitability of the selected components must be assessed against the applicable standards.
RT III Wash-Tight Construction for PCB Applications
A distinguishing feature of the .0001 variant is its RT III wash-tight environmental protection. This construction is intended to provide protection during specified PCB soldering and washing processes, making the relay particularly useful for electronic equipment manufacturers using compatible automated assembly methods.
The relay's PCB through-hole terminals support direct soldering into printed circuit boards, while its compact housing provides four changeover contact sets without requiring four separate relay components. This can simplify circuit layout, reduce component count and make more efficient use of PCB space.
The silver nickel (AgNi) contacts are suitable for a broad range of general-purpose electrical switching applications. Engineers should select the relay according to the actual load characteristics, particularly when switching inductive loads, motors or circuits with high inrush current. The 7 A contact rating applies under specified conditions and should not be interpreted as a universal rating for every load type.
Reliable 12 V DC Coil Operation
The 12 V DC coil makes the Finder 55.14.9.012.0001 suitable for compatible industrial electronic control systems and DC-powered equipment. With a nominal coil resistance of 140 Ω, the relay draws approximately 86 mA at its rated voltage, corresponding to a nominal power consumption of around 1 W.
As a monostable relay, it remains in its energised switching position only while the appropriate coil supply is applied. This provides predictable switching behaviour for general-purpose control circuits. When designing the driving electronics, suitable coil suppression should be considered, as suppression components can influence the relay's release characteristics.
