E91 is a long block Grade 2 contact, built with 1m of 4-core cable. Internals are sealed with the supplied fly lead exiting from the side. EOL resistors are easy to add for a supervised circuit, using a suitable JB to house the additional wiring. Contact and magnet housings are made from cast aluminium, ensuring a durable and hard-wearing product. For extra durability, see code E92 for a variant with armoured fly lead.
