Tacho generators manufacturer by primary firms may be installed on the encoder: tacho generator model and manufacturer are at customer's choose.
High reliability in a wide temperature range and high-frequency response are assured by use of LED light source (100000 hours minimun operating life), push-pull connection of detecting phototransistors, professional components, accurate design engineering, remarkable mechanical sturdiness thanks to all-metal construction, and several tests at high and low temperatures.
The number of pulses/rev. is from minimum of 1 up to a maximum of 3600 (in according to those available for each model).
Upon request it's possible to match a centrifugal relay to the tacho generator unit.
