Spectra Symbol HotPot Potentiometers

Spectra Symbol HotPot Potentiometers are linear position sensors for high temperatures and environments. These sensors feature high lifecycle, high-temperature capability, 3M Pressure Sensitive Adhesive (PSA), and are made from fiberglass substrate. The HotPot potentiometers deliver 10kΩ standard resistance, 5kΩ to 100kΩ custom resistance range, -40°C to 85°C operating temperature range, and >10 million lifecycles. These potentiometers are ideal for industrial, military, and automotive applications.

Features

High lifecycle
High-temperature capability
Linear position sensor
IP65 dustproof and waterproof (intense spray)
Fiberglass substrate
3M Pressure Sensitive Adhesive (PSA)
Repeatability:
- No hysteresis, but with any wiper looseness, some hysteresis will occur
1Watt maximum @ 25°C, ≤0.5Watt recommended power rating (depending on size, varies with length and temperature)

Resolution:
- Analog output is theoretically infinite; affected by variation of contact wiper surface area
Upon request:
- Male or female Nicomatic connectors
- Wiper of 1Newton to 3Newton force to actuate part
- Contactless options available
No affect @ 95% RH, 24hrs 60°C humidity
