Budget estimate

$400 – $1,000

The exact unit price is not disclosed. Similar Emerson TOPWORX proximity switches typically retail between $150‑$300 each, depending on configuration and volume discounts. Assuming a modest discount for a municipal purchase, the total contract value could range from roughly $300 (2 × $150) on the low end to $1,000 (including taxes, shipping, and any service fees) on the high end. Factors influencing the final amount include negotiated unit price, freight costs to the Columbus address, and any applicable local taxes.
