Alternating / Sequencing Relays/Struthers-Dunn/ Struthers-Dunn 311 Series – Sequence Stepper Relay 5A

Struthers-Dunn 311 Series – Sequence Stepper Relay 5A

The 311 Series relays are sequencing (stepper) relays built on the industrial 219 style frame. Hold down clip is integral to the relay base. Double pole contacts transfer on energizing of coil or de-energizing. Dual cam movement allows contacts to operate together or separately. Works equally well with application of continuous voltage to coil or energy saving impulse. No continuous voltage required for memory. Numerous custom switching arrangements are possible over 8 steps per revolution of the cams.

Customer Testimonials

"I was at my wits end. I looked all over for this one part. I figured I would make one last call to Universal. It turns out hard to find parts are their specialty.
