Airbags have been designed to help protect adults in a moderate to severe frontal collision. To do this, the passenger’s front airbag is quite large, and it can inflate with enough force to cause very serious injuries.
There are conditions where the automatic shut off feature will not completely insure safety (seat too far forward, small child in a car seat), there could be a need to manually disarm the passeger sode airbag.

Even though the vehicle  may include an advanced front airbag system that automatically turns the passenger’s front airbag off, all manufacturers offer a manual cutoff system for an additional measure of safety.
These manual systems are typically activated or deactivated by turning them using the vehicle´s  ignition key.

Piher has developed a rotary switch that seamlessly adapts to these systems and reliably actuates the transition between the “on” and “off” states.

Potentiometer for appliances. Detented control mechanism.

file icon DCM-PTT datasheet.Tooltip 04/15/2016 Hits: 2118

Multifunction potentiometer - encoder - switch for appliances.

The DCM-PTT potentiometer offers sturdiness, performance and adaptability where frequent human-machine-interface adjustment is required.

Its robust design allows for employment of different mechanisms, such as a selecting a program/function in your dishwasher or setting the temperature of a cooktop.  

Different ouptput choices are available (incremental encoder-pulse, rotary switch, absolute-analog potentiometer) and safety measures such as push-to-turn.

Detent number, connectors, mounting flanges, tact switch function and other features can be studied upon request.  

Typical applications include consumer electronics, ovens and other kitchen appliances, white and brown goods, automotive HVACR and personal care control panels.

This datasheet shows you the basics of this potentiometer that is quite versatile.

Do not hesitate to contact Piher specialists for further advice.

file icon E-15 datasheet.Tooltip 04/15/2016 Hits: 1970

360º customiseable incremental encoder.

The Model STS-15 offers engineers an endless rotation SMD version of the popular PT-15 rotary control. This 360° version adds endless clockwise (CW or CCW) rotation as a part of the current features of the PT-15s already highly configurable mechanical and electrical specifications. That means a wide variety of off-the-shelf mounting methods, custom ohmic (resistance) values, tight linearity performance, along with the six different rotor designs.


This potentiometer offers product designers the flexibility of allowing users full rotational access across the normal stops that have, up to now, limited mechanical rotation. With this design feature, engineers can now design product command features over a 340° range (active electrical travel).


For maximum design versatility, the endless rotation feature can be combined upon request with detents to provide users tactile feedback on each setting and selection – with up to 51 unique detent positions. Virtually any appliance rotary control requirement can be configured using the PT-15’s wide range of standard features. Other interesting optional features include stop positions (detents), a variety of rotors, long life and custom electrical angles.


Engineered to serve as a highly cost-effective control potentiometer for most consumer applications such as ovens, ranges, dishwashers, power hand tools, washing machines and HVAC systems, it also can fit many automotive convenience electronic
applications.

file icon Hall-effect Speed SensorTooltip 08/25/2020 Hits: 33

Piher`s flange mount gear tooth speed sensors have  been designed to precisely calculate the speed and direction in demading enviroments such as vehicle’s transmission.

In-house R&D interdisciplinary teams dive deep to help you solve complex challenges thanks to over 60 years of experience and leadership in tried and tested technologies.

Custom product design packaging can be easily provided to meet any form, fit and function including the choice of wire harness and interface connector.


Applications

• Vehicle transmission
• Wheel speed  
• Engine speed  
• Anti-lock braking systems
• Speedometers
• Automation systems. Anti-lock braking systems. Camshaft & crankshaft speed / position / direction. Flow meter, Anti-Skid / traction control. Spedometers. Tachometers. Linear & rotary encoder. Conveyor belt speed and distance. Hoist speed and direction. Pump speed feedback. Stop motion detector. CNC machines. Sproket speed. Counters. Wind turbines.

Piher’s High Speed Inductive Position Sensor are used by hybrid/electric vehicles powertrain systems to feedback the angular position, direction and speed of the rotor shaft to optimize control of the motor inverter.

The position sensor can be mounted on the same shaft as the electric machine rotor and sensing its position accurately is critical in order to drive the motor optimally by the vehicle’s control unit.

This solution provides high speed rotary motion sensing with a robust design against external magnetic interference fields generated from sources such as electric motors.

It uses the physical principles of induction in a wire loop and eddy currents to detect the position of a solid metallic structure that is sliding or rotating above a set of coils consisting of one transmitter coil and two receiver coils.

Hollow shaft magnetic rotary angle and position sensor-control.


Key features
• Simple & Robust magnetic design.
• Endless rotation.
• Programmable switch output.
• Programmable Linear Transfer Characteristics
(some positive slopes & one negative slope can be programmed in the same transfer characteristic;
up to 4 programmable points; see last page).
• Self-diagnostic features.
• Over voltage protection and reverse voltage protection.


Also upon request:
• True full redundant version.

Examples of applications:
• Non-Contacting long life angle/position sensor.
• Absolute rotary position sensor
• Pedal position Sensor.
• Turn counter.
• Throttle/EGR valve and gear position sensor.
• Height & suspension sensor.
• Non-contacting potentiometer.
• Float-level sensor.
• Motor-shaft position sensor.
• Precision robotics, material handling, industrial equipment, HVAC monitoring & control, etc.

The MTS-360 provides a true breakthrough in contactless sensor technology by combining a through-shaft design with 360º absolute position feedback in an ultra miniature size. The result is the smallest fully featured rotary sensor on the market with reliability up to 50 million cycles.


With its tiny size, engineers can now integrate a fully featured rotary sensor directly on their PCB without the packaging issues that typically accompany encoders or other absolute position devices. The exceptionally low profile fits easily in places that were previously too small for pre-packaged rotary sensors.


This ultra-miniature Rotary Position Sensor is ideal in optical imaging stabilization and precision biomedical devices, optical zoom devices, consumer electronics, instrumentation, HVAC systems, automotive control systems, marine controls, fork lift trucks, farm equipment, cranes, low speed motor feedback, valve position sensors and robotic and automation feedback system.
