Safety Interlock Switches

Transcription

1 r Safety Interlock Switches Compact Universal Tongue- Operated Safety Interlock Switch Strong and versatile the compact size of the strong, glass-filled polyester housing can be used in many applications NEMA 6 enclosure enables these switches to withstand water washdown cleaning Rotatable head gives four possible actuator entry points for versatile installation. A blanking plug is supplied for the unused entry. Small swing radius allows use on doors with a swing radius as small as 64 mm (2. in.) when using the optional flexible 1 actuator with alignment guide Vibration resistant optional catch and retainer keeps vibrating guard doors shut, preventing unwanted opening of guard doors on vibrating machines Long life these switches, with their stainless steel actuators, are designed for a minimum of one million actuations Optional connector makes installation quick and easy An optional stainless steel head is available Specifications Electrical Contact Configurations: Safety Contacts: Switching Ability Safety Contact ap: Auxiliary Contacts: Max Switching Current/Volt/Amp: Minimum Current: Electrical Life: Mechanical Mounting: Mounting Hardware: Actuator Travel for Positive Opening: Min Operating Radius: Break Contact Min Force: Max Actuation Speed: Max Actuation Frequency: Case Material: Actuator Material: Wiring Entry: All Models 2 N/C or 1 N/C + 1 N/O 2 N/C or 1 N/C positive break AC: 00 V 1 A, 20 V 2 A, 100 V A DC: 20 V 0.

2 Safety Interlock Switches Operation Optional Catch & Retainer 12 Blanking plug for unused entry. The head rotates 180 to give 4 possible actuator entry points. The catch and retainer is used to keep guards on vibrating machinery closed. Holding force = 0 N (11.2 lbs.). Actuator alignment guide for use with flexible actuators. Optional Alignment uide & Flexible Actuators Flex 1 flexibility in any direction. Optional SLD Series Optional switch locking devices are available. See accessories section for details.
