90.20 SMA FINDER 8-Pin Undecal DIN-Rail Screw Terminal Relay Socket
The 90.20 SMA FINDER (Finder Type 90.20.SMA) is an industrial-grade 8-pin undecal (octal) screw terminal socket engineered specifically for Finder 60 series industrial plug-in relays (DPDT / 2 Changeover contacts, model 60.12). Designed for panel mounting or direct 35 mm DIN-rail attachment, the 90.20 SMA FINDER provides a robust, high-dielectric electrical interface between control cabinet wiring and octal-base relays in automation circuits, power distribution setups, and shipboard electrical systems.
Housed in a durable blue thermoplastic casing, the 90.20 SMA FINDER features heavy-duty rising clamp screw terminals rated for 250V AC insulation at up to 10A per pole. It includes an integrated cavity for Finder 99.01 series LED status indicators and EMC suppression modules, along with mounting slots for metallic retaining clips (type 090.33) to prevent relay loosening under continuous operational shock and vibration.
Key Features of the 90.20 SMA FINDER
-
Designed for Finder 60.12 Relays: Native 8-pin undecal (octal) circular pin layout for 2-pole DPDT 60 series plug-in relays.
-
Dual DIN-Rail & Panel Mounting: Snap-mounts onto standard $35\text{ mm}$ DIN rail (EN 60715) or mounts directly to backplates via integrated mounting screw holes.
-
Screw Clamp Terminals: Secure rising-clamp screw connections accommodate solid or stranded conductors up to $2.5\text{ mm}^2$ (14 AWG) for dependable signal transmission.
-
Integrated EMC/LED Module Slot: Internal socket cavity accepts Finder 99.01 series status LEDs, RC suppression circuits, and protective varistors.
-
Retaining Clip Locking Mechanism: Compatible with 090.33 metallic retaining clips for vibration-proof relay retention in high-shock industrial environments.
-
Logical Terminal Identification: Clear numerical pin marking following EN standards streamlines initial panel wiring, commissioning, and routine service maintenance.
Primary Applications
-
Industrial Automation & Motor Control Panels: Interfacing octal-base 8-pin power relays with PLCs, timers, and safety controllers
-
Marine Telemetry & Generator Systems: Providing secure relay socket connections for engine monitoring, alarm circuits, and generator transfer switching
-
Power Distribution & HVAC Control: Switching auxiliary loads, contactor coils, and solenoid valves in commercial and industrial distribution boards
