AMS 39-640 Sensit 2 Snack Vending Machine – 5-Wide, MDB/DEX, Refurbished

AMS 39-640 Sensit 2 Snack Vending Machine (Refurbished, 5-Wide)

The AMS 39-640 Sensit 2 snack vending machine is a full-size, 5-wide glass-front snack vendor built by Automated Merchandising Systems (AMS) — one of the most serviceable and location-proven snack platforms on the used market. This refurbished unit has been gone through and tested to be working 100%, and it ships configured with 1 candy tray and 5 chip trays, giving you a clean mix of shelf-stable snacks, chips, candy and pastries in a single cabinet.

What makes the Model 39 stand out is the patented Sensit guaranteed-delivery system: an infrared sensor scans the delivery bin and confirms the product actually dropped. If a snack hangs on the coil, the shopper is offered another selection or an automatic refund — which cuts refund calls and builds repeat traffic at unattended locations. The glass front lets customers see every product, and the wide 5-column layout keeps popular chips and candy stocked longer between service visits.

About Automated Merchandising Systems (AMS)

Automated Merchandising Systems is a US manufacturer based in Kearneysville, West Virginia, that has built the Model 39 glass-front vendor family for decades. AMS is respected by route operators for straightforward mechanical design, deep parts availability, and its Sensit guaranteed-delivery technology — making refurbished 39s some of the easiest machines to keep running for years. You can review the manufacturer’s platform details at the AMS official site.

Where This Machine Earns

A 5-wide AMS 39 is a workhorse for medium-to-high traffic indoor locations: offices and break rooms, warehouses and manufacturing floors, gyms, apartment and dorm common areas, auto shops, hotels, and healthcare or laundromat lobbies. With 1 candy and 5 chip trays you can merchandise chips, candy, cookies, crackers, granola and gum side by side, and the wide columns typically hold enough facings to stretch the interval between restocks. As with any unattended machine, real returns depend on foot traffic, product mix and pricing — a well-placed snack vendor typically pays for itself faster in a captive-audience site than in low-traffic retail.

Condition & What’s Included

This is a refurbished AMS 39-640: the unit has been gone through, cleaned, and tested to operate 100%. It arrives with the 1 candy / 5 chip tray configuration, a rebuilt 3-tube coin mechanism, a $1 bill validator, and a brand-new lock with 2 keys. A credit-card reader is not included but the MDB bay is ready for one — you can add a reader for $389 after purchase, and the bill validator and coin mech can be upgraded for an additional charge if you want higher-denomination acceptance.

Refurbished machines carry our 1-year limited warranty (replacement parts, labor and remote tech support for US customers); new machines carry a 2-year tier.
