Supply voltage (using voltage range) DC12 ~ 24 v pulse (p - p) below 10% (DC10 ~ 40 v) Current consumption - 13 under the ma Switch capacity - open collector output, below 200 ma Residual voltage, under 2 v (when load current is 200 ma, cable 2 m long) Refers to the display (yellow) lights -- Action form (close to the test object) C1 / B1 type: NO C2 / B2 type: NC Protection circuit, reverse connect protection, surge absorption, load short circuit protection When environment temperature - action, save: each - 40 ~ + 85 ℃ (not ice, condensation) Environmental humidity - action, save: 35 ~ 95% RH The influence of the temperature Temperature range - 23 ℃ ~ + 85 ℃ to + 40, plus or minus 15% detection distance Temperature range to 25 + 23 ℃ ~ + 70 ℃, + / - 10% detection distance Voltage - the influence of plus or minus 15% rated supply voltage range, rated supply voltage, + / - 1% detection distanceInsulation resistance -- more than 50 m Ω (DC500V shaking table) between the shell and charge department Electric pressure - AC1, 50/60 hz, 000 v between the shell and 1 min charge department Vibration (durable) -- 10 ~ 55 hz fluctuation amplitude is 1.5 mm 2 h X, Y, Z direction Impact (durability), 500 m/s2 X, Y, Z direction 10 times each 1000 m/s X, Y, Z direction 10 times each Protection IP67 structure - IEC specifications Connections - 1, wire type derivation (standard cable 2 m long) 2, plug and socket type Material is qualitative, shell (SUS303) stainless steel and brass Note: * 1. The average frequency for dc switch department reply. Measurement conditions: with a standard test objects, test object spacing for the standard detection of 2 1/2 times, setting distance to detect distance. * 2. The M8 type in the range of 70 ~ 85 ℃ when used, using voltage range for DC10 ~ 30 v, control output capacity (switch) for under 100 ma.
