IDEM - the UK’s largest designer and manufacturer of Machine Safety Switches have the solution to your application requirements. N ot content being the largest designer and manufacturer of safety switches in the UK, IDEM Safety Switches also design and manufacture the largest Stainless Steel range of machine safety switches in the world covering all industry sectors including food processing, packaging, petrochemical and pharmaceuticals. Some of the harshest environments for instrumentation and machinery are found here. To combat these environments the best metal to use is Stainless Steel 316. With this in mind IDEM produced the world’s first highspec. range of mechanical and noncontact interlock switches with fully Stainless Steel 316 housings. Housings are tested to IP69K with features that ensure high reliability and long life performance. Many switches have mirror polished finishes and are aesthetically designed to reduce or eliminate food traps. high tolerance to misalignment, LED indication of switch status, “antitamper” coded magnetic actuation and various switching circuits to cope with modern industrial control requirements providing up to PLe Cat 4 ISO13849-1 and SIL3 EN62061. The “HYGIEMAG” range of magnetic non-contact safety switches, the sister products to Hygiecode offer noncontact high power magnetic switching up to 230V.ac 2A. They provide guard door interlocking in applications found in food processing, packaging, pharmaceutical and petro-chemical industries. Housing designs, surface finish and aesthetic styling allows them to be used in almost any environment subject to high levels of cleaning following contamination from foreign particles. seal gasket and give highly reliable, repeatable enclosure sealing. All housings, actuators and fittings are Stainless Steel 316. Flexible actuators are available to assist with guard alignment. They have 4 pole contact blocks and the switch head is rotatable to allow up to eight different actuator entry positions. IDEM’s range of Heavy Duty Stainless Steel 316 Emergency Stop safety switches have been developed to provide robust emergency stop operation for machines and conveyors. The “HYGIECODE”’ Non Contact range offers various housing shapes to provide environmental protection to 105°C with suitability for high pressure chemical wash down to IP69K. Housings have mirror polished finishes, full encapsulation using high-spec. materials then sealed with a stainless steel back plate for extra mechanical and environmental durability. The high specification enclosures offer a wide 14mm sensing distance, IDEM’s “HYGIELOCK” range of solenoid operated guard locking switches are designed with unique patented locking mechanisms incorporating two positively guided switch contact blocks providing independent monitoring of solenoid lock and actuator position (guard closed/open). Rugged design and mechanism provide guard holding up to 2000N. (200kg). Two LED’s provide diagnostic indication of solenoid and lock status in a range of solenoid voltages (24/110/230V ac/ dc). The “HYGIECAM” range of traditional Tongue Interlock switches are fully Stainless Steel, designed with double In various sizes they have additional features including double seal lid gaskets and specially designed safety trip mechanisms forcing safety contacts to open if the lid is removed and offered with a choice of 3 or 4 pole contact blocks. Variants include button protection shrouds preventing damage to buttons and padlock holes to allow “lock off” for additional level of protection during maintenance. Rope Pull E-Stops are availab
