TL-PP702 ^Type
Flat Proximity Switch
 Features
 Two-wire DC proximity switch with built-in
connector.
 4 mm in thickness.
 Prevention of connector disconnection and
improvement of insertion easiness achieved
with the use of compatible positive lock
connector.
 Principle of operation
An impedance change in the detection coil of the
high-frequency electronic oscillator allows a
metallic object to be detected.

25 to 85% RH
Effect of temperature Within the temperature range of -10 to 60 deg C, the rate of change in the detection
range must be within ±20% relative to the range provided at 23 deg C.
Effect of voltage
Within the ±10% variation in the rated voltage, the rate of change in the detection
range must be within ±5%.
