Daiwa Dengyo SPT-22 Safety Plug – Two Circuits 250V 15A

Daiwa Dengyo SPT-22 Safety Plug is a robust standard model within the SPT series, specifically engineered for industrial applications requiring dual-circuit control. Designed to handle electrical ratings up to 250V and 15A, this plug offers a reliable solution for safety interlocking and power isolation. Its durable construction and secure bolt nut attachment make it an ideal choice for machinery requiring redundant safety measures or simultaneous circuit switching.

Description

Daiwa Dengyo SPT-22 Safety Plug is designed to meet the complex needs of modern industrial automation, distinguishing itself from single-circuit models by offering true two-circuit functionality. This capability is facilitated by its specific wiring configuration, allowing engineers to manage two separate electrical lines simultaneously, which is often a requirement for safety redundancy or complex control logic.

Technically, the SPT-22 is highly versatile. While it is robust enough to manage substantial power loads of 250V at 15A, it is also sensitive enough to reliably conduct minimum loads of 24V at 5mA. This dual capability ensures that the plug can be used effectively in both high-power drive circuits and low-voltage signal transmission systems (such as PLCs) without contact failure.

Installation and durability are central to the SPT-22 design. The unit features a handle-hand attachment secured by bolt nuts, preventing accidental removal due to vibration or operational movement. It is designed to fit seamlessly into control panels, accommodating mounting plate thicknesses of up to 6mm, and utilizes 4 x M4 wiring terminals to ensure a secure and organized connection for both circuits.
