SRH280
The SRH280 sealed rotary sensor has been specially developed to meet the harsh requirements of today'sautomotive, motorsport and industrial position sensing applications. Interchangeable with the popular 38mm
fixing centres format, several innovative features are included to increase the reliability and performance over
similar devices already in service. The contactless operating principle makes this sensor particularly suitable for
applications where a high level of dither vibration is present.
Crush proof inserts
The sensor housing is a highstrength glass-filled engineeringpolymer that has the added featureof stainless steel inserts around themounting screw area sopreventing damage to the flangeby over-tightening. This permitsthe sensor to be re-used afterinstallation and allows minuteadjustments to be made.
Shaft attachment
The sensor shaft has the option oftwo attachment formats that areinterchangeable with existinginstallations. The sprung shaft style isa one-piece design that eliminatesfailures caused by more common two-piece designs. The shaft can be sealedto meet IP50 or IP68 protection.
Cable outlet
The sensor rear housing has an integrally moulded cable fully sealed to IP68, effectivelyeliminating the need to over-fit a moulded boot to improve sealing, thus saving the user timeand cost. To facilitate the addition of supplementary heatshrink sleeving over the cable, asmall lip on the moulding assists attachment at the sensor housing. The standard cablelength supplied is 0.5m.
SRH880
submersible contactless rotary sensor
The SRH880 submersible contactless rotary sensor has been specifically developed to meet the harsh operatingenvironments in heavy duty industrial position sensing applications, including construction, agricultural andmilitary vehicles, steelworks and power generation plants. The contactless operating principle makes this sensorparticularly suitable for applications where a high level of dither vibration is present. The sensor is sealed to
meet IP68M protection.
Choice of mounting
The sensor can be mounted by three M6clearance holes through the body, oralternatively by three M6 threaded attachmentholes in the front face. The sensor shaft has aflat on the diameter that would allow it to besecured by a locking screw, or an optional leverkit can be used to attach to the moving surface viaa selection of M8 threaded holes.
Rugged design - superior protection
The rugged, 88mm diameter housing in a choice of aluminium or stainless steel, includes a stainless steel operating shaftsupported by a heavy duty, twin ball-race
bearing system for maximum strength. Environmental protection is achieved by aunique double
sealing system that allows the sensor to operate fully submerged to 2m.
