⚡ At a Glance
- • Contact Capacity: Contact capacity listed as 20A 240VAC / 30A 240VAC with SPST contact
- • Best for: Lighting, small motors, cooling fans and PCB-level control in automation or remote control
- • Not ideal for: High-density relay banks without adequate spacing due to recommended 30mm clearance
Compact SPST PCB relay with a DC 12V coil for switching moderate AC loads. Supplied as a pack of five with flame-retardant PC housing and four metal pins for PCB mounting.
Reliable switching for moderate loads - with a DC 12V coil and SPST contact
A DC 12V coil energises the internal armature to close a single-pole single-throw contact, allowing current flow up to the specified amperage. Contact rating is given as 20A 240VAC / 30A 240VAC in the product description.
Useful for controlling lamps, small heating elements, motors and fans from common 12V control circuits without complex wiring.
Space-efficient PCB mounting - with a four-pin layout and small footprint
Footprint measures approximately 31 x 27 x 23mm with four PCB pins for through-hole mounting. When multiple relays are installed, a 30mm spacing is recommended to reduce heat buildup.
Fits neatly onto hobby and industrial PCBs while allowing straightforward soldering and reliable board-level connections when spacing is observed.
Safer, longer-lasting enclosure - with flame-retardant PC surface and robust pins
The outer shell uses flame-retardant polycarbonate material that resists high temperatures and deformation. Metal pins are specified for good conductivity and stable contact resistance.
Adds resilience under thermal stress and produces steadier electrical connections, reducing maintenance in small control systems.
