Servo Instrument Corporation

Servo Instrument Corporation, a woman-owned small business based in Baraboo, Wisconsin, manufactures precision electronic components—variable resistors, potentiometer assemblies, resistance elements, sensor sticks, and motion transducers—for the Defense Logistics Agency as a prime contractor (100% of recent awards), competing across full-and-open and small-business set-aside categories without exclusive reliance on either posture.

Servo's footprint is heavily concentrated with the Defense Logistics Agency. The top three funding agencies account for 90% of recent awards: DLA Land and Maritime leads with 633 awards valued at $10.3 million combined potential value, followed by DLA Aviation with 105 awards and $2.6 million, and a residual DLA line with 115 awards at $343 thousand. Five awards each from Naval Supply Systems Command and the Army round out the active set, representing marginal customer diversification. The dollar concentration tracks the award count—DLA Land and Maritime anchors 71% of combined potential value, while DLA Aviation adds 18%, making DLA components the near-exclusive customer base.

Servo holds multiple indefinite-delivery contracts across DLA Land and Maritime and DLA Aviation, each with ceilings near $250,000. Representative recent vehicles include single-award IDCs valued at $350,000 (March 2026, Land and Maritime, no set-aside), $350,000 (December 2025, Land and Maritime, Total Small Business), $250,000 (November 2025, Land and Maritime, no set-aside), and $249,999.99 (December 2024, Aviation, no set-aside). The source documents at least fifteen active IDVs across both DLA components, enabling delivery-order procurement on an as-needed basis for electronic components supporting military maintenance, testing, calibration, and repair.

Recent awards exemplify the work: a $26,250 Total Small Business purchase order from DLA Land and Maritime for potentiometer assemblies (February 2026), a $38,882.50 delivery order from DLA Aviation for sensor stick position components (September 2025), a $31,800 full-and-open competitive purchase order from Land and Maritime for variable resistors (October 2024), and a $32,199.30 purchase order for variable resistors from Land and Maritime (March 2023). Award values typically range from under $1,000 to $60,000 per task order, reflecting high-velocity, low-unit-value procurement patterns characteristic of DLA's spare-parts supply chain.

Activity has remained steady over the past five years—44 awards in 2022, 40 in 2023, 35 in 2024, 35 in 2025—with a compressed 2026 sample of 5 awards as of mid-March. Eleven awards (combined potential value $166 thousand) reach ultimate completion within the next twenty-four months and face recompete exposure. Servo operates from its Baraboo facility and subcontracts minimally; a single Boeing sub-award (November 2024) for a foreign military sales administrative modification represents the only documented teaming relationship in the source. The vendor's category concentration is extreme: 394 awards under NAICS 334416 (Capacitor, Resistor, Coil, Transformer, and Other Inductor Manufacturing), 159 under Electronic Resistor Manufacturing, and the remainder scattered across miscellaneous manufacturing and aircraft accessories. PSC coding shows 816 awards under Resistors, with the balance in aircraft accessories, instruments, and antennas.

Servo competes in a high-volume, low-dollar-value, full-and-open-plus-small-business posture where it has established itself as DLA's default supply source for specialized electronic components across both Land and Maritime and Aviation components. The customer concentration and award velocity suggest a mature, stable supply relationship rather than growth or competitive exposure.
