In combination with a dual channel safety monitoring relay IDEM’s Guardian Line Series Grab Wire Safety Rope Switch System can be used as emergency stop devices monitored for up to Category 4 to EN 954-1 or PLe ISO 13849-1.

All conform to ISO 13850 and IEC 60947-5-5 and they have a positive mechanical linkage between the switch contacts and the wire rope. The switches have wire breakage monitoring.

On pulling the rope, anywhere along the length, the safety contacts are positively opened and the auxiliary contacts are closed. The switches are mechanically latched and can then only be returned to the operational condition by pressing the blue reset button as required by ISO 13950.

An optional 2 color LED indicator is available to enable switch status to be viewed from a distance.

psa-msa-standalone-coded-non-contact-220x220

They have their own internal monitoring system and use force guided mechanical contacts and will maintain PLe/Category 4 (ISO13849-1) even with switches connected in series.

They are offered in high specification plastic or stainless steel housings and can be used in virtually any environment including high-pressure cleaning following contamination from foreign particles. The housings are compact and easy to fit on less than 40mm frame sections.

The PSA (plastic) switch and the MSA (Stainless Steel 316) switch both have IP69K ingress protection and are suitable for most detergent washdown applications. The MSA (Stainless Steel 316) switch has a Mirror Polished Surface Finish (Ra4) and is suitable for CIP and SIP cleaning applications.

Dual Actuator versions are also available for use with “double door” guards.

The typical sensing distance “on” is 12mm with wide tolerance to guard misalignment after setting.

SAFETY RELIABILITY (ISO 13849-1) PLe Cat. 4:

All standalone switches employ 2 Force Guided Mechanical Relays and incorporate internal checking to ensure both relays are operational after each safety demand. If one relay fails to open or becomes inoperative the switch will lock out safe. Switches can be connected in series to maintain PLe/Category 4 to ISO13849-1.
