The D4BL, D4GL and D4NL guard-locking safety switches ensure that movable
guards are locked during operation and cannot be opened until dangerous
conditions have been removed. These switches are intended for use, for example,
where the stopping time of a dangerous movement is longer than the time that a
person needs to reach into the hazardous area (machines with large amounts of
inertia for instance), and for ovens, which may present a danger of burning to
personnel. |

The D4BS and D4DS safety door interlocking switches are intended for machines
with fast shut-down times. They prevent the machine from starting until the
guard is closed and automatically stop the machine if the guard is opened during
operation, protecting the operator against possible danger. These switches
comply with EN1088. |

The D4DH hinge safety switch
and the D4GS miniature safety key switch are designed for use with safety
doors that form the entrance to protected areas in production systems and
machines. The heads of both switches can be mounted in different positions
for installation flexibility.

The D4GS has a special third
contact that enables it to be used as a cross-fault safety switch for
category 4 applications. Its very compact dimensions make the D4GS ideal
for use where space is limited, and its IP67 rating makes it suitable for
operating in extreme environment conditions |

Omron's D4BN, D4DN and D4DR
are general purpose limit switches with a range of actuators for
object over-travel and guard detection. Typical applications include
elevators, escalators and conveyors.
The miniaturised D4F offers up to 4
contacts with the minimum of space in a metal housing.
The switches are equipped with direct opening contacts as defined in
EN60947-5-1 'low voltage switchgear', and the D4DR
is equipped with a manual reset, which is ideal for situations where a
visual check of the problem is required prior to the reset of the switch.
