NPT version can be sealed with a curing type thread sealant such as "Loctite 565" with primer "N". Do NOT use PTFE tape. When correctly sealed. Do NOT over-tighten as this can permanently damage the sensor. CIRCUIT DIAGRAMS In order to suit any application, these sensors have been designed with various output circuit configurations. They are identified by the 3-digit code at the end of the part number as shown in Order Information. 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 Generate your specific part number using the convention shown below. Use only those letters and numbers that correspond to the sensor and output options you require -- omit those you do not.
