Safety Technique
SAFEMASTER C
Multifunctional Safety Timer
UG 6960

Product Description

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.
