Small Safety Bundle - 1 Channel

HS7A-DMP Non-contact magnetic safety interlock switches perform the same functions as standard mechanical safety interlock switches, but are designed to be used in applications where non contact is desired between the switch and its actuating key. It's also being used where space is at a premium. The slim profile makes it easy to mount in locations out of the way of personnel and machine operation, reducing the possibility of damage or misalignment.

Key Features

• Compact rectangular 25 x 88 x 13 mm

• 1NO+2NC, or 2NO+1NC contacts

• Models with 2m, 5m, and 10 cable length

• Models with LED indicator

• Up to 36 sets can be connected

• IP67 protection

• B10d: 5.0E+07

Machine safety design is a detailed topic addressed by many regulations and standards, and it is also supported by numerous specialty products and practices.

However, this doesn&rsquo t ensure appropriate machine safety measures are always applied. There is a strong tendency among many designers to presume that machinery must come to a full stop when errors are detected. This belief, along with overly conservative interpretations of ISO standards, has led many designers to handle most situations as category 3 or 4, requiring full redundancy. In 2015, ISO 13849 was revised and the requirements for category 2 were updated becoming easier for users incorporate into their machine safety systems.

Instead of mandating full redundancy as with categories 3 or 4, when category 2 is acceptable, only single input connections, less expensive controllers, and single outputs can be used. Design effort is reduced, the safety controllers relay modules are more economical, fewer and less-specialized non-redundant devices can be used, control panel space is saved, and field installation labor is reduced.

Key Features

• The first category 2safety relay module in the industry

• Ideal for low-risk machines

• Safety with non-redundant safety circuit.

• Push-in terminals save installation labor and prevent loosening of wires

• Slim body save control panel space
