Multifunctional safety timer with instantaneous contacts
UG 6960

The multifunction safety timer UG 6960 provides protection of men and machines by enabling and disabling a safety circuit. This is done by the adjusted time delay function. Simply select 1 out of 5 delay functions with a rotary switch – ready. The adjusted time is safe over the complete setting range. The UG 6960 is available for different safety functions. It has safe delayed and instantaneous contacts.
