Consult factory. 2. 18 is standard. Specify lead length in inches (max. 48). e.g. -FL18 or -FLS30. 3. 18 is standard. Specify lead length in inches (max. 48). e.g. -EL18 or -EL30. 4. 36 is minimum. Specify cable length in inches. e.g. -CAB36 or -CAB120. 5. DIN connectors require -C SPDT circuit. 6. Requires -10A, -G options (50% increase in deadband typical). 7. Options -10A, -G or -RD cannot be combined. 8. Ingress Protection is available only with -FL, -FLS, -ELS or -CAB Electrical Termination choices. Ingress Protection requires Fixed Set Point -FS. 9. Set Point must be within Pressure Range selected in Step 1. Table 1 -- Vacuum Range Codes The deadband values tabulated are for the standard microswitch. With either the -SP of -10A option, the deadband values are typically 50% greater than those listed. With the -RD option, the values will be typically 25% less than those listed. In certain applications deadband can be tailored and controlled to customer specifications. Consult factory for details.
