Daiwa Dengyo SPT-22-G Safety Plug – 250V 15A Guide Rib Interlock

Daiwa Dengyo SPT-22-G Safety Plug is a robust interlock device designed to eliminate connection errors in industrial environments. Distinguished by its integrated alignment feature, a guide rib is placed on the plug and socket to identify the precise mating position, ensuring smooth and accurate insertion every time. Rated for 250V and 15A, this plug offers a secure and user-friendly solution for safety circuits requiring frequent operation.

Description

Precision Mating with Guide Rib Technology In fast-paced industrial settings, ensuring the correct alignment of safety plugs is crucial for both efficiency and equipment longevity. The Daiwa Dengyo SPT-22-G Safety Plug addresses this challenge with a specially designed guide rib structure. This feature physically guides the plug into the socket, allowing operators to instantly identify the correct mating position. This not only speeds up the connection process but also prevents damage to the contact pins caused by forced misalignment.

Heavy-Duty Connectivity Beyond its ergonomic design, the SPT-22-G is built for electrical reliability. It features 4 x M4 wiring terminals, providing a secure and vibration-resistant interface for dual-circuit configurations. The device is versatile enough to handle substantial power loads of up to 250V and 15A, while maintaining the sensitivity required for low-voltage control signals down to 24V, 5mA.

Rugged Construction Durability is a hallmark of the SPT series. The handle-hand attachment is secured using bolt nuts, ensuring the handle remains firmly attached even under mechanical stress. Additionally, this model accommodates thicker mounting surfaces compared to standard units, supporting mounting plate thicknesses of up to 6mm.
