Selection & installation notes
- The original selection image is used for contact combinations: its B/C/D/F mappings differ from the prose. Confirm the exact order-code circuit diagram before integrating the switch.
- The image defines A as mechanical locking/electromagnetic release and G as electromagnetic locking/mechanical release. They have different loss-of-power behaviour and are not interchangeable.
- The -B LED option is marked AC/DC 10–115 V in the naming image; this is not the 24 VDC actuator supply. The prose conflates these values and also mentions Pg13.5; confirm terminal and cable-entry drawings.
- The published force and life values do not establish a complete-machine safety performance level. Select, wire and validate the guard-interlocking system against the machine risk assessment and exact product documentation.
- Use a matched actuator, verify alignment and stopping conditions, and isolate hazardous energy before mechanical release or maintenance. Do not bypass the guard switch.
