The 1800 types are fixed timers, while the 1900 models are adjustable via an external resistor. The 1 Form A (SPST-NO) switch is rated 300mA. Adjustable Timing Formula (1900 types) The resistance required to obtain timing within this range is determined by using the formula: Rx = 400K (T/Tmax.) – 40K, where Rx = External Resistance in Ohms, T - Desired Time in Seconds, and Tmax. = Maximum Time (Code). A high quality deposited carbon ±1%, 0.1W (min.) resistor is recommended for external resistance. A typical part number would be 1811–1A–1002. This fixed timing module operates at -55°C to +85°C, has hook terminals, style “A” mounting, and a time delay of 10s. .892 [22.66] 1.32 MAX. [33.53] .406 MAX. [10.31] .040-.047 [1.02-1.19] .809 MAX.

The timing code consists of four digits and gives the time in ms. The first three digits are the significant figures and the last digit is the number of zeros following the significant figures; thus 50 ms would be coded 0500, 1.1 s would read 1101, and 1 m (60 s) would be 6002. Adjustable timers cover one decade, e.g., 62 ms to 620 ms. The upper decade limit is Tmax. in the timing formula and is the the value defined by the timing code in the part number. 1.062 [26.97] BLUE BEAD LOAD POWER Part Numbering System Outline Dimensions .187 MAX.
