PQ50S
■General
PQ50
The PQ series is an interface connector designed to
handle high power/signal connections in industrial
machinery. Available in a water-resistant or non-water-
resistant type, they are capable of handling up to 12.5A/
pin (PQ50S and PQ50W) or 19A/pin (PQ50).
Side locking structure emits a tactile click and produces a secure lock
Clear tactile
click!
■Features
PQ50 and PQ50S Series [ Non water-resistant type ]
1. Side locking spring structure delivers a clear tactile
click.
The left and right buttons disengage the mated lock.
(Side locking system). The easy mating operation delivers a clear
tactile click. (Fig.1)
2. Strengthened cable clamps
Cable clamp strength is 98N or more. (* Actual is 400N or more.)
The structure will prevent the mated connecter and clamp from
detaching against excessive forces.
Easy extraction

3. Different cover options
A robust, enhanced, shielded die-cast shell is available on the PQ50
series or a engineered, light weight plated plastic resin shell for the
PQ50S series.
The die cast shell delivers an enhanced EMI shield on the PQ50
series and the plated plastic resin of the PQ50S series’ cover case
and panel shell ensure ESD and EMI performance.
4. Coding key system provides flexibility with multiple options
The coding key system prevents incorrect mating and has multiple
variations available.
Female Contact
5. Rear mounted panel shell is available.
After attaching the panel shell to the chassis, it is possible to install
or remove the crimp housing. (Fig.2)
Fig.2
Easy and reliable ground connection
6. Reliable ground connection structure.
The crimp contacts can be mounted directly onto the panel shell
with screws which enhances the grounding connections. (Fig.3)
7. Supports NFPA79 compliant cables (with 600V capability).
(PQ50 Series)
Due to restrictions on the AWM cables by NFPA79 revision, the
requirements of listed cables has increased for wires used in
industrial machines in the U.S.A. This product complies with the
restrictions and requirements of NFPA79.

[Water-resistant type] PQ50W Series
Special locking structure with lever
1. Water resistant (IP65)
Rated at IP65 when in the mated condition.
2. Special locking structure.
Special lever and cam structure delivers easier operation and assists
with the insertion and extraction of this connector. (Fig.1)
3. Rear mounted unit offers easy operations.
Male and Female plastic crimp case can be installed not only for
panel side metal shell but also plug side one. (Fig.2)

4. Metal plated cover of engineering plastic resin adds
strength and EMI protection.
This robust connector uses a metal plated material of special
engineering plastic for the cover and panel shell to ensure high ESD
and EMI performance.

Supports mounting from the backside of the panel
5. Independent ground contact structure.
Secure grounding is accomplished by use of the plated plastic cover
and the independent ground contacts. (Fig.3)

Independent Ground Contacts
1. Available contact options
Two styles are available; one with 19A/pin contacts or one with
12.5A/pin contacts.
2. Lance protection structure
The side wall of the contact prevents lance deformation and helps to
prevent tangled wires. (Fig.4)
3. Sequential contacts of different length are available
Two types of different contact length are available for the male
contact. (Fig.5)
Independent Ground Contacts
4. Highly reliable contact structure
The female contact assures a reliable connection by using multiple
contact points and a unique spring structure. (Fig.6)
