SLS 220
LINEAR DISPLACEMENT SENSOR
SLS220 linear
displacement sensors have a 10mm or 20mm stroke range with aspring loaded operation and a mounting flange to allow easy installation.
Contained within a high strength Nylatron
® housing, this provides good chemicalresistance and low weight. The internal potentiometer assembly is protected to
IP66. Suited to OEM and process monitoring applications, this new sensor
replaces Penny+Giles HLP220 model. Ω at 500VdcVoltage divider only - see Circuit Recommendation below

CIRCUITRECOMMENDATION
Hybrid track
potentiometers feature a high wiper contact resistance, therefore operational checks should be carried out only in the voltage divider mode. Hybrid track potentiometers should be used only as voltage dividers, with a minimum wiper circuit impedance of 100 x track resistance or 0.5M
