Aleph Automotive Sensors

auto-sensors

The ALEPH Corporation of Japan has over 30 years experience in the manufacturing of specialized reed switches and magnetic sensors, and has used this experience in the development of G, Speed and Shock Sensors designed to activate automotive safety systems. As well as safety sensors, ALEPH supplies conventional sensing devices which provide other necessary information about the condition of the vehicle.

A2 – ANTILOCK BRAKING SYSTEM

Speed Sensor (rev sensor)

This electromagnetic induction-type sensor detects the change in magnetic flux caused by the revolution of a rotor mounted on the vehicle shaft. The signal pulse is transmitted to the control unit and used to control the ABS and active suspension.

B – TEMPERATURE DETECTION

Thermal reed switches

Abnormal radiator water temperature and 4WD transmission system temperature can be detected by thermal reed switches, which are a combination of a normal reed switch in a heat-sensitive ferrite casing. These devices can be manufactured to switch at specific temperatures.

C – DAMAGED LAMP DETECTION

Reed switches

Reed switches combined with coils are able to detect damaged lamps, including burnt-out headlights and rear lights.

D – FLUID LEVEL DETECTION

Level sensors

These sensors warn if the liquid levels in the brake master cylinder, cooling system and wash/wipe reservoir fall.

E – POWER SEAT POSITIONING

Reed switches

These reed switches detect the limit of the longitudinal movement of electrical power seats and the reclining angle.

F – OPEN/CLOSED DOOR PROTECTION

Proximity sensor

A reed switch type proximity sensor detects whether the door is open or closed and can be linked to an alarm system or internal lighting for security and convenience.

G – SEAT BELT TENSIONING

Shock sensor

This reed switch type shock sensor tighten and locks the seat belt instantaneously (20 – 30ms) when an impact of above 2 G is experience. It is normally used in combination with an airbag system.

H – SUSPENSION LEVELING CONTROL

Reed Switches

A combination of multiple reed switches and magnets sense uneven loading of the vehicle and trigger the suspension levelling system for safer driving. Opto sensors can also be used for this application.

I – BOOT/TRUNK LID PROTECTION

This reed type switch can be used to indicate the open/closed state of the lid for safety control. It can also be linked to a security system to prevent theft.
