Voltages applicable to output value stated. OUTLINE DRAWING HOUSING SPECIFICATIONS All dimensions shown in mm. Tolerances = 1mm. Housing Series - External Mounting Type 1 Thread Type 1 Type 2 M12x1x8g M12x1x8g with hex nutc Pressured 7 bar / 101 psi maximum Tightening Torque 1.5 Nm / 13.26 in-lbs maximum Type 2 Housing Series - Internal Mounting Thread Type 3 Type 5 M12x1x8g with hex nutc M10x1 Pressured Tightening Torque 7 bar / 101 psi maximum 1.5 Nm / 13.26 in-lbs maximum Not Applicable Type 3 NOTE: In the cases of Type 1 and Type 3 sensors, the rear of the SST sensors are slightly longer than the Honeywell sensors. NOTE: The dimensions of the Type 5 part make it a "push in" part the same as LLE105100. Note that the sensor can also be secured using an M10 nut. ELECTRICAL INTERFACE Type 5 NOTES c) d) Hex nut and washer supplied with Type 1, Type 2 and Type 3. When correctly sealed. Wire Designation Red Vs Green Output Blue 0V CIRCUIT DIAGRAM CAUTION: Take care when connecting loads. The minimum load impedance should not exceed Vs/max output current. Note: Shorting the output to Vs or 0V will result in irreparable damage to the sensor. ORDER INFORMATION Specify the part number you require.
