Sensing Components & Indicators
At FridayParts, we stock sensing components and indicators that help off-road and non-road machines report what’s happening in real time—so we can stop guessing and fix problems faster. When a warning light shows up, or a machine derates, the root cause is often a failed sensor signal, a bad connector, or an out-of-range reading.
This category focuses on the parts: sensors that measure pressure, temperature, speed, and position, plus indicators that show restriction, direction, lighting status, or dashboard warnings. We build and supply high-quality parts at affordable prices, designed to match common equipment fitment needs in the market.
Which Sensor Do You Need?
| Type | What it measures | Common signal/fit notes | Common symptoms when failing |
| Pressure sensor | Boost, differential pressure, system pressure | Often 3-wire (5V/Signal/Ground); sealing matte | Power loss, wrong readings, frequent warnings |
| Temperature sensor | Coolant, intake, hydraulic, or component temp | Resistance-based or digital; check connector pins | Hard starting, fan issues, overheating alerts |
| Speed sensor | Shaft/gear speed, wheel speed | Magnetic pickup or Hall-effect; the gap is critical | Erratic shifting, limp mode, no speed reading |
| Position sensor | Lever/actuator position | Calibration may be required on install | Jerky control, bad response, fault codes |
| Angle sensor | Steering/boom angle | Mounting alignment matters | Drift, steering faults, and control instability |
| Level sensor | Fuel/DEF/fluid level | Float or electronic; tank grounding matters | False empty/full, warning lights, shutdown risk |
| Indicators | Restriction, lighting, and dash status | Must match voltage and connector style | No warning, wrong warning, dead panel lights |
Browse FridayParts sensing components and indicators by brand or equipment, confirm fitment, and order affordable, high-quality replacements that help your machine run steady again.
