Telemecanique Sensors ATEX KM-SS-Ex Safety Interlock Switch, Keyed Lock Style, 2 NC Safety Contacts, Stainless Steel 204019

IDEM 204019 KM-SS-Ex Safety Interlock Switch is a high-quality explosion-proof device with keyed lock style, stainless steel housing, and IP67 rating, designed for hazardous industrial environments.

This safety interlock switch includes two normally closed (2 NC) contacts rated at 4A and supports both 250V AC and DC voltages. The robust construction from stainless steel 316 provides resistance against corrosion, chemicals, and high temperature washdown, making it ideal for demanding industries such as food processing, pharmaceuticals, packaging, and petrochemical facilities.

The KM-SS-Ex series features positive break contacts certified to IEC 60947-5-1 and has been tested for high functional safety standards ISO 13849-1 and EN62061. The switch has a tamper-resistant key mechanism and eight actuator entry positions, ensuring precise and secure guarding on sliding, hinged, or lift-off machine guards.

The device is ATEX certified and suitable for use in European zones 1, 2, 21, and 22 hazardous areas, complying with IECEx and ATEX EExd IIC T6 standards for gas and dust. It offers protection up to IP67 and includes pre-wired three-meter cable for ease of installation.

The compact design measures 41.6 mm width, 118 mm length, and 44 mm depth. Its rotatable stainless steel head and rugged body provide reliable safety interlock detection in extreme industrial conditions. The switch can be integrated with most safety relays to achieve up to Category 4 PLe according to ISO13849-1 and SIL3 per EN62061.
