Index provides components and custom-engineered products to Original Equipment Manufacturers (OEMs) in a variety of fields such as:

Heavy-duty highway (truck & bus), automotive, construction, agriculture or lawn care, marine, defense, power generation, and assorted industrial applications.

Pressure Sensors

Index provides pressure sensors for both vehicle and industrial applications to measure fuel, oil, and air pressure.

• Operating pressures available up to 15,000psi.
• Available in absolute pressure, gauge pressure, and differential pressure.
• Numerous thread sizing, connector options, and wire lengths available.

Pressure Switches

Mechanical high-reliability single-point on/off control device; commonly used for fuel, oil, or air pressure in vehicle and industrial applications.

• Tight environmental seal perfect for heavy-duty applications
• Full range configurations available. (set points, connectors, or thread sizes)
• Available in different wire lengths

Temperature Sensors

Designed for a wide variety of heavy-duty and industrial applications, our temperature sensors are available in 2-wire, 3-wire active, 4-wire PWM, and dual-function configurations.

• Pressure-Temperature Sensors Provides dual-function sensing in a single port.
• Pulse Width Modulation (PWM)
  Standalone device that provides variable speed fan control.

Temperature Switches

Index offers customisable mechanical and electronic temperature switches with a variety of set and reset-points. Available in both single and multiple outputs.

• Mechanical Temperature Switches set-point switches engineered to last for over a million cycles.
• Electronic Temperature Switches Multiple set-point switches, ideal for engines, transmissions, fuel, and fan control; also available with time delay.
• Multiple thread sizes, wire lengths, and connectors available (screw, spade, integrated, or with a wired connector).

Level Sensors

Index offers capacitive level, resistive level, and water in fuel sensors. These stand-alone devices provide a digital signal reflecting coolant level or water in fuel status.

• Available in a 3- or 4-pin Metri-Pack® connector or with an optional adapter harness.
• Resistive Liquid Level Sensors Designed to offer high sensitivity in conductive fluids.
• Capacitive Liquid Level Sensors Covered probe ensures no contact between sensing element and liquid; typically used in non-conductive fluids.
• Water in Fuel Sensors A resistive level sensor optimised for detecting water in oil or diesel fuel.

Level Probes

Passive devices for either coolant level or water in fuel alerting; requires an external module to function.

• Low Coolant Level Probes Eliminate engine failure caused by faulty coolant level signals.
• Water in Fuel Probes Safeguards engine performance by detecting and signalling the presence of water in the fuel system.

A/C Protection

Our A/C modules go beyond monitoring conditions of low or high pressure and voltage. They stop damaging events, such as over-cycling within the A/C system.

AC-X10 Detects rapid cycling and protects from under-voltage. The AC-X10 eliminates heat build up as well as delays the A/C clutch engagement to extend the compressor’s life.

APAds™ Its microprocessor-based intelligence offers all the protection of the AC-X10, plus on-board diagnostics and year-round compressor lubrication.

Position & ABS Sensors

Our quality position and ABS sensors are available for many heavy-duty on and off-road applications.

• Upsized cable for increased abrasion resistance.
• Robust encapsulation and sealing to protect the internal components from environmental contamination.
• Corrosion-resistant coatings and glass filled nylon ensuring long life in harsh environments.
• Multiple cable extension options available.
